This gorgeous video shows you the journey of a photon from the sun (well, the surface of the sun, I imagine – the journey from core to surface of the sun takes far, far, far longer), out into the solar system and all the way past the inner, rocky worlds until it reaches mighty Jupiter, king of the planets, all taken in real time. The speed of light is fast – the fastest thing we know of (so far, not counting possible existence of supralight particles). So fast, as one writer observed, that most civilisations take millennia to realise light even travels at all. But when you move out into the vast distances of space even the speed of light seems tardy by comparison. It’s some eight minutes and twenty seconds just to reach us on Earth, and we’re only the third rock from the sun. “Riding Light” takes us out beyond the terrestrial worlds – Mercury, Venus, Mars, Earth – then on, avoiding the tumbling asteroid belt, until it reaches magnificent Jupiter, some forty five minutes later:

“That whole time, that’s the time I call ‘sitting on God’s front porch.”
Those are the words of Gene Cernan, naval aviator, engineer and NASA astronaut, on his three days on the Moon as commander of Apollo 17. The last of the spectacular lunar Apollo missions. Gene was, quite literally, the last man on the Moon. Astronauts, cosmonauts, taikonauts, they’re a select cadre, a group who even now, more than fifty years after the first manned space flight by Gagarin, are composed of only a tiny group of people, the few who have flown above the clouds, above the very air we breathe, to enter space, to float around our glowingly blue world and see it as no-one else in the history of the world could have before space flight.
But among that select group the trailblazers of that first era of manned space flight stand out – Gagarin, Glenn, Shepherd, Leonov. These men really did go where no-one has gone before. Spaceflight is incredibly dangerous – you ride into orbit at vast velocity atop what is basically a carefully controlled series of explosions with a thousand things that can go wrong, to enter an environment Earthbound life was never meant to survive in, where a small mistake or fault can lead to death. And in the first years it was all entirely new – nobody even knew for sure if humans could live in space, could you even eat and digest while weightless in your orbiting capsule? Would cosmic rays kill you or fry your electronics leaving you adrift before you could do anything? Could you survive re-entry?
(Above: Cernan poses for an official portrait in his spacesuit; below: Cerna in a less formal pose with his young daughter)
Cernan was there right in the earliest days, one of those elite pilots recruited for the astronaut corps, starting with the Gemini programme, and this film draws principally on his autobiography. Cernan starts as the reserve crewmember but after an awful flying accident to the main crew he is moved up to the mission – rather mixed feelings, to say the least, getting his dream tickets, a chance to soar into space, but getting that first chance because his friend and fellow flyer died tragically. And that part covering the early years of Cernan’s life at NASA , sets the tone for this entire film – this isn’t just about those first astronauts, about the setbacks and the triumphs. Those have been documented many times – deservedly – but here we have a much more personal and importantly a much more emotional film. This is still about those gloriously heady days, pushing to be the first to reach the Moon, but it is just as much about the emotional and psychological cost for the astronauts and their families.
“If you think going to the Moon is hard, you ought to try staying home” – Cernan’s wife on hearing of a flight mishap during Apollo 10.
Cernan, to his credit, does not try to paint himself or his fellow Apollo astronauts who take part in this film as the simple, heroic figures history likes to portray. Which is not to downplay in any way the risks they faced, the amazing science and engineering it involved, the boundaries they pushed, the new frontier they charted. It was heroic. And like most things heroic it is too easy to forget behind those stories there is just a normal person – doing the extraordinary, to be sure, but still a person, like any of us. A person with loved ones around them who have to share that dream with them, who also have to sacrifice, who suffer emotionally. Not just the obvious worry over whether husband/dad/brother will come home safely. We’ve all seen those prim, seemingly serene NASA wives of the period watching the mission on TV with their kids and projecting the expected image of pride and confidence when really they were terrified of what could happen, but would never show it in front of the camera.
Cernan pulls no punches on that front – he comments that in many ways the astronauts were quite simply selfish; oriented totally on their goal, the mission, the training. Meanwhile real life was rolling on and it was the wives who had to make sure the kids were looked after, got to school on time, the bills were paid, household chores and repairs were done. Wives essentially had largely absentee husbands, children absentee fathers; they couldn’t stop training or being focused on the mission, there were only a few flight slots and only the best of the best would get that chance. And so they sacrificed – on the job, Cernan paying his dues flying Gemini then Apollo 10, the last flight before Armstrong’s historic landing, so close he could almost touch the Moon but knowing that first landing was not to be his (his respect for Neil shines through any disappointment at that). And it was a vital part of proving they could get men there and fly home, critical to the success of Apollo 11. As Cernan notes of those preparatory missions – “Not many people remember Apollo 10, but I do. And I’ll tell you someone else who did – Neil Armstrong.”
And later he gets his ultimate reward – and what a reward, what the calls his “personal moment of reckoning”, command of Apollo 17. With cutbacks looming after several successive lunar missions, it will be the final one leaving some who trained and were ready for their mission to never reach that goal. Where Armstrong and Aldarin have a short time on the surface the later missions had several days and the remarkable Lunar Rover, a hi-tech, Space-Age dune buddy for the Moon, so they could travel further and explore more, pick up more diverse samples to study back on Earth. And in an incredibly touching moment Cernan recounts how he parked the Lunar Rover for the last time, a little away from the landing module (LEM) so it could remotely film their take off.
(Cernan on the Moon, by the Lunar Rover, the red commander’s stripes marking this out as his suit; below, the view from the trip round the Moon, the Apollo missions the very first time any human being had been far enough away to see the entire disc of our world, and to to share that image with all of us. We’ve grown up knowing what our entire globe looks like hanging in space, something all the thousands of generations before the late 60s never got to see)
And as he dismounted to walk back to the ship for the final time he paused. And there in the ancient, dusty surface of the Moon he wrote his young daughter’s initials. Which, like Armstrong’s footprints will, in that airless vacuum, essentially remain there forever. As far from home as any humans have ever been, sacrificed so much home and family life to be there, to land on the Moon, and suddenly all he can think of is home and his wee girl. It’s beautifully touching. If any future mission – and who knew back then that almost four decades on we’d still not have returned – lands and visit the Rover, those initials will still be there.
“Walking up the ladder was probably one of the most memorable moments for me, because I looked down at my footprints and I knew I wasn’t coming this way again. Why were we here, what did it mean? I looked over my shoulder: there’s the Earth, there’s reality, there’s home. I wanted to press the freeze button, I wanted to stop time, I really wanted to reach out, take it in my hand, stick it in my spacesuit and bring it home to show to everybody, this is what it looks like, this is what it feels like.”
And the last man to walk on a surface not of our Earth climbed the ladder to the LEM and Apollo 17 headed home. But it still wasn’t over, not really. Hard to recall now, but the early astronauts were global figures, international celebrities in a way the preening media darlings of today could never dream of, with tens of thousands lining routes to wave to them on visit. From Gagarin through to the Apollo crews, they travelled the world – presidents, celebrities, scientists, millions of ordinary people, all wanted to see them, to hear them speak, the glare of media followed them, and as Cernan’s then wife notes it becomes too much. They sacrificed for years for his training and the mission, and now it is over, but still they are in the spotlight – when do they get to be a regular family, have an ordinary life again? Too much for many – some sixty percent of the Apollo astronauts, including Cernan, would end up divorced due to the stresses and strains. The physical return to Plane Earth was relatively gentle, a splashdown in the ocean, but the emotional and psychological effects of having to come back to Planet Earth, to real, daily life, was far bumpier.
(tired and covered in Lunar dust – making history can be dirty)
This emotional core is absolutely central to director Craig’s film here, and it gives a much more satisfyingly rounded and human insight into some of the most remarkable moments in recent human history, and those who made them happen. He doesn’t stint on the astonishing nature of the Moon missions or the glories of Apollo – period film, both NASA and family home movies and photos, all create visuals for both the missions and the families dealing with the effects of training for those historic flights, while some very well-done CG effects are added to the visuals, giving us a view we otherwise simply couldn’t have. But he balances this constantly with what it cost in terms of emotional and family life to do what they did.
And there are some wonderfully emotional scenes from the present day – Cernan returning to the Cape, to the old Apollo launch pad. It looks like the sort of thing any good film-maker would shoot – the subject returning to the scene of their greatest triumphs, where it all happened, where the roar of the awesomely powerful Saturn V rockets lifted men not just into space but all the way to the Moon and back. Except towards the end it is clear Cernan has not entirely enjoyed this stroll down memory lane, looking at the now empty, unused Apollo launch areas and thinking that he really doesn’t like seeing it like this, that perhaps he should not have come back to see it this way.
(Cernan as he is today, re-visiting the Apollo launch pad, where world-changing history was made, now all silent – a bittersweet moment for the astronaut)
And in another immensely touching scene we see Cernan visit the Johnson Space Center, Houston. And there is the capsule from Apollo 17, from that defining, historic mission, the peak of his astronaut career. And it’s a museum piece, viewed by school children not born until decades after he flew in it. He looks at the capsule, still showing the raging fires of re-entry on the shell, and the dummy astronauts inside. Did we really do it, he muses, did we really reach out and do what humans have dreamed of forever, to touch the Moon? What was it all about? How do young people today see this item in a museum and the old man standing by it, looking just like anyone’s grandfather (and indeed he is). Was it all a dream? Did he really once fly in that small spaceship? What will people in another forty years or a hundred or a thousand think looking back at the Apollo days?
I’ve been in love with the idea of spaceflight since I was a very small boy, born at the height of the Space Age; I’ve read and watched so much of the history of those times and those world-changing events. Despite all the documentaries I’ve watched, the books I’ve read, this film still stood out, largely because of that very emotional core, giving a hugely satisfying new insight into those remarkable Apollo days, the human side to the heroic giants who rode fire into the heavens. For fellow space geeks like me this is essential viewing, but for those who just enjoy seeing epic history being presented at a very human level, this is also a remarkable film.
The Last Man on the Moon opens in the UK on April 8th, and there is a special screening with live link up for a Q&A with Gene Cernan on April 11th in many cinemas around the country.

Jim Ottaviani, Leland Purvis,
I’ve long been fascinated with the life and work of Alan Turing, the remarkable British mathematician and boffin (and if anyone deserves the affectionate old British label “boffin”, surely it’s Turing), the ideas, far ahead of his time and the technology available to him, spilling out of that unusual mind like a brilliant river of thought that most of us would struggle to stay afloat in, let alone navigate that river. Ideas which changed the world, although for many long decades some of that astonishing work would be concealed under the Official Secrets Act, wartime work not to be discussed. And it wasn’t; from the eccentric academics with their erratic, lateral-thinking brains tackling seemingly impossible problems to the legions of women who sweated over the operations at Bletchley Park, they kept their mouths closed. Some, like Turing, would go to their graves long before the nature of their work was revealed, the role it played in saving the nation – and arguably the free world – from the dark tyranny of the Nazi onslaught.
And as if helping save the world was not enough, also using those desperate times to push the envelope, advancing ideas and new technologies which would otherwise have taken years or decades more, birthing the proper digital programmable computer (in hastily erected sheds in wartime Britain of all places). Birthing the technological creations which would take us from the Industrial Age into the Information Age, a revolution we’re all mostly still running to catch up with, an idea which, like Gutenberg’s movable type printing press before it was an idea which would branch off into so many other areas, influencing every aspect of our lives, from everyday things like train travel or making a phone call to the exotic, like launching satellites or creating new ways of peering into our bodies to create new treatments. And some of those first ideas come from a young, eccentric and awkward, but brilliant, lad, ideas which may have remained only theories and academic papers and perhaps the odd bit of mechanical or electronic tinkering, if the budget allowed, until the war came.
Ottaviani (who previously brought us a wonderful biography on the great Feynman) and Purvis break this look at Turing’s life and mind into three main parts, starting with his youth – school and college days, home life – then answering the call of duty during the dark days of the Second World War for secret work at the (now rightly famous) Bletchley Park, the desperate, frantic attempts to find ways into the supposedly unbreakable Enigma codes, and then his post-war life, able to show his OBE for services to “king and country” but not to ever tell what that remarkable work actually was. And of course, for those of us already familiar with Turing (I’ve admired him since I sat programming my first home computers, way back in the days when you had to learn programming to make them do anything, long, long before apps and swipes) that last act is a tragic one (potential spoiler alert for those not familiar with that history).
It would have been very easy to focus entirely on those Bletchley Park years, and indeed the material from that period would easily have filled the book. But to Ottaviani Purvis’ great credit they want to show the person, not just the historical figure, and it greatly enriches the book by taking in his younger years first. The awkward lad with a brilliant brain that seems to grasp hugely complex problems easily and solve most of them just in his head (where the rest of us would fill entire journals working on the problem for years and still be scratching our heads), and yet to whom many of the normal everyday social interactional skills were a mystery (these days it’s hard not to imagine Jim Parsons’ wonderful portrayal of Dr Sheldon Cooper when noticing these quirks).
But there are still warm, social connections there despite his awkwardness, from family, from a few select friends, including Chris Morcom, a young, intelligent friend who accepts him as he is, and who other biographers have speculated about – was he perhaps young Turing’s first crush as he realised he preferred men to women? Here that isn’t exactly downplayed, but neither is it highlighted, instead, rather nicely focusing on their friendship and shared interests, sadly doomed to end all to early as Morcom died very young (the scenes following that are both sad and very touching, showing Turing the man, not just a brilliant brain, but a person with feelings).
Some of the book follows Turing himself, showing him at school, college, being invited to America to Princeton where he is in the company of the likes of Von Neumman, Alonzo Church (even Einstein was there during this period), then into the wartime work and realising some of his ideas about “universal machines” could be used to help crack these Nazi cyphers, first by mechanical means (the famous “bombes” rotating and clacking away by the hundred, staffed by service woman often working in their undies due to the heat of the machinery) then (with the brilliant electronic engineering of the GPO’s Tommy Flowers) an actual electronic, digital computer, the first such in world history (although as it was a state secret for decades afterwards textbooks would give that honour to American scientists. Again those who worked on it kept their lips sealed about their much earlier efforts).
At many other points the book deviates from this approach, instead bringing in people who knew him, friends, colleagues, his mother, even his wartime fiance (who accepted even though she knew he was homosexual, because he liked her time with him), taking their turns in the interview chair, introducing parts of Turing’s life that they were involved in, as if in a documentary film. Again this very much helps personalise this story – it isn’t just about an odd but brilliant mind, it’s a person and the people who were around them. I also very much approved of the many nods to others from Bletchley, such as Dilly Knox or the “golden geese” (the servicewomen who worked there – as Churchill called the vital Bletchley decrypts, it was the goose which laid the golden eggs but never cackled. This was an era where one did one’s duties, all in it together, and did not talk about it. Most maintained that silence for decades until their work was declassified). The Bletchley segment is also something of a celebration of the “backroom boys”, the great British Boffin, the sort of chap with a brilliant mind solving amazing problems in time of need, and yet the sort who often forgets to tie his own shoelaces.
And then there is that final act, the tragic act (again spoiler for those who are not familiar with this history and don’t want to know in advance of reading the book). The postwar work, struggling to get resources like they had during the war to continue his early computing work, and the nature of his homosexuality also coming out, no real, continuing romantic relationship, just the odd fling, giving an impression of sadness and loneliness, also of frustration at work he can’t advance as much as he wants. And finally the fling which lands him before the judicial system, because this was 1950s Britain and homosexuality wasn’t just frowned upon, it was actually illegal. His status and service saved him from prison, but cruelly he was put on a probation that included taking female hormones to “cure” him, causing him illness, weight gain and even developing breasts, provoking despair and depression and more isolation. Until this brilliant man, whose work had been absolutely pivotal to the survival of the entire nation, takes his own life with a poisoned apple (beautifully foreshadowed much earlier in the book as he and a college chum go to see the new Disney film, Snow White).
The disgrace of a man who had rendered such service to his country, to be treated so is shocking still, and the question that can never be answered echoes heavily over this last chapter – what else could have come from that brilliant mind? What other innovations would Turing have given to the fledgling computer industry? But despite this terribly sad ending this is not downbeat, this is a celebration of a remarkable man and an astonishing life. Purvis uses some wonderful visual tricks to convey the processes of Turing’s mind – a scene showing the ticker tape for an early thought experiment machine flowing past him as he effortlessly walks on and his friends struggle to keep up with him was rather wonderful, likewise a fantasy scene with Turing talking with the brilliant Ada Lovelace – another innovator of the world we now live in – is beautifully depicted, and there are lovely little cameos, including a young officer from Naval Intelligence, Commander Ian Fleming (later to create the James Bond novels).
It’s a beautifully told story, both for those of us with some familiarity with Turing and that historical period, and to those who are new to it, a reminder also of the enormous debt the present and future always owe to the past and those who came before us, and what they achieved, often in the face of adversity; it celebrates an amazing man and the people he worked with. In 2009 the British Prime Minister issued a posthumous apology to Turing for his judicial treatment, in 2013 the Queen officially granted a royal pardon. Computer scientists, cognitive psychologists and philosophers are still debating Turing’s thought experiments on advanced computing technology actually being able to develop into artificial intelligence, his importance and work are still taught in academia around the globe.

I’ve very much been looking forward to Knockabout publishing Jen Harder’s Alpha, the first of a projected three graphic works which aim to take in one of the grandest themes a book can tackle: life, the universe and everything, from the fizzing, bizarre microseconds around the Big Bang when even the universal laws of physics and nature hadn’t yet taken effect (in fact they didn’t yet exist as we know them) through the slow birth of stars, planets, whole galaxies, then the molten lumps which would grow and reform to become one planet in particular, our own beautiful Earth.
In Alpha Harder takes us on a mind-blowing head-trip through some four and a half billion years (give or take) from the “let there be light” moment to formation of the Earth, the endless ages of changes, the first sparks of life, the astonishing spectacle of evolution, of great geological processes, from the beginning right through to the Anthropocene era, the “human era”. And as a subtle reminder that humans are not as special as we like to think we are, we come in only at the very end of this volume, comparative latecomers in the great book of life on Earth.
The Beta and Gamma volumes are aiming to look at the rise of humans, form primitive ape-like forms to modern humans and establishing civilisations then potential futures, but those are stories for other days, and while I very much want to read those, Alpha offers up more than enough imagery, spectacle, amazement and food for thought for any reader to mentally digest.
“At first only a germ exists, the singularity. From this infinitely hot and dense original state, no bigger than a football, the Universe expands. An inflation commences. The beginning of Space-Time.”
The breadth and scope of Alpha is remarkable, and Jens has the confidence to trust his readers and their own ability and knowledge, frequently giving us entire pages without text, just images, trusting his readers to participate with him, to be an active part of this story telling experiment. And what a story – the great story, the one philosophers, sages, religious leaders and scientists alike have explored since… Well, for as long as humans have been capable of thought. The first section come across very much like a fantastic voyage, spectacular images splashed across our retinas, from the infinitely small world of sub-atomic physics, quarks, of matter and anti-matter springing into being and annihilating one another, then to the much larger scale, to the cosmological scale. Hydrogen gas accumulating, gravity starting to exert its power billions of years before Isaac Newton would lay down his laws. Atoms are formed, stable substances, they start to group together under the influence of gravity.
As they clump together they are changed, enlarged, spinning, turning, growing. From simple dust and gas will come the most massive of structures: swirling gas spins before our eyes, faster, faster, heat generated by the friction, the rotation, pressures building from being so squashed together until heat and pressure pass the point of no return and this accumulation of matter ignite: nuclear fusion takes place at their heart and the first stars burn into existence, fuelling in turn the creation of more elements, while around these new stars more rocks come together, slowly, oh so slowly forming what will become the planets. It will take billions of years, but these cold rocks smashing together will one day become vast, complex ecospheres of their own, especially our own remarkable world.
We move from the cosmic to the Earthly, to a world we wouldn’t recognise, one we couldn’t actually live on – the atmosphere, such as it was, poison to us and to most other life we know of, no water yet, the surface crust just the thinnest covering over raging magma, constantly bombarded by debris from the formation of the solar system. And yet this volcanic hell-world is destined to become the richest and most diverse source of life in our entire solar system. Wind and water start to form on this embryonic planet, shaping it as much as the geological movements do, that spinning metal core starts to generate a magnetic field, deflecting the worst cosmic rays, an invisible umbrella that will encourage and protect the endless variety of life to come.
And that life too will change the form of the Earth, the earliest lifeforms breathing the foul atmosphere and excreting oxygen. We can even still see some of those incredibly ancient lifeforms, such as the Stromatolites off the coast of the great island continent of Australia. We know that mighty oaks come from a humble acorn, but here Jens graphically shows us the almost miraculous formation of worlds, stars and life, from the most primitive bacteria which would eventually lead to swimming creatures, then backbones, eyes, legs. Giant sea scorpions, massive dinosaurs, the rise of the mammals, the waves of extinctions and the new forms which would emerge to take their place, a never-ending cycle of death and new life while around that life the Earth itself, seemingly so solid to short-lived beings like us, is continually changed, altered, mountains rise, erode, entire continents move and reform…
Jens doesn’t just offer up imagery of these events though – throughout the entire book he constantly inserts frames from much, much later, from our own human culture era, into the events. The slow coalescing of gases into the spark of nuclear ignition that forms a living star comes across like a NASA countdown. 5, 4, 3, 2, 1, we have ignition, and appropriately this sequence is intercut with the mighty blast of human-built rockets defying gravity to launch a spacecraft beyond our world. The growing power of the young sun bathing the early planets is intercut with more human imagery, Egyptian pharaohs and their children beneath the all-powerful sun-god Ra (or perhaps it is the Aten sun-god of the heretic king Akhenaten). Early creatures experiencing celluar division are contrasted with mythological beings from Incan and Mayan civilisations.
Sequences depicting the first order out of chaos as the laws of physics establish themselves following the Big Bang are intercut with human desires to impose order on nature, the swirl of the subatomic coming together to form the larger-scale reality intercut with the creation of the great Pantheon and its wondrous dome by the Romans. The embryonic seas form in a sequence intercut with Hokusai’s famous Great Wave artwork. Depictions of continental drift are contrasted with delightfully inaccurate and yet still so beautiful medieval Mappa Mundi, the amazing new life forms of the great beasts contrasted with woodcut images from a bestiary, the era of the giant “terror birds” with Alice meeting Dodo, the evolutionary adaptation of skeletons to move from sea to land with the structure of the mighty Forth Rail Bridge, nature and human culture and invention entwined repeatedly.
It’s a remarkable experience; this journey across unbelievably vast tracts of time and creation is mind-bending. It puts me in mind of The Light of Other Days, a collaboration between Stephen Baxter and the great Arthur C Clarke, in which wormhole technology allows humans to look anywhere in time and space, one character following his own family line back, back, back, his mother, father, grandparents, following them visually all the way back to early hominids and further back. But here, unlike Clark and Baxter, we are moving forward, not back, sailing through space-time and history and evolution.
And while the concepts are as vast and complex as the timescales and lifeforms they depict, this counter-cutting the story of creation with human images puts a scale on it we can understand, while also reminding us strongly that we’re not different, we’re not apart from all of this, we are an integral part of this magnificent chain of creation. It also subtly hints that out of all of those billions of years and different lifeforms, we are the only ones we know of who have established an understanding of these things, and even then only comparatively recently.
It’s only a few hundred years since Hooke explored the microscopic world we never even knew existed before that period, even more recent since we started to understand world-shaping concepts like continental drift or stellar physics or sub-atomic physics or the Darwinian notions of evolution, barely half a century since we discovered DNA or set foot on a surface that was not part of our own world, but another celestial body. And yet all those new discoveries and knowledge are all connected with what went before, standing on the shoulders of giants, our precious knowledge showcased so wonderfully here also part of that same great chain of circumstances across billions of years which allowed the conditions for these things to happen, these creatures to be, these people to exist, to think…
It is both incredibly humbling, putting us in our place, just another part of a long cycle of life, and yet also exalting humanity for being the only life on Earth to be able to comprehend and celebrate this knowledge. Humans are a part of this creation, not aside from or above it, but a part of it, the latest in a long, oh so long chain of events leading to the conditions for life, then for that life to slowly evolve into beings who could regard this universe and start to read it’s history like a book, to start lifting back the heavy curtains of Dark Matter to peer at the very structures of the universe or to explore the book of life through DNA or the extensive fossil record our remarkable world has furnished us with and start putting together those stories. Which are our stories, the stories of all life.
This is a spectacular book, a ride through the creation of everything, leaving the head spinning, flooded with ideas, imagery, offering new lenses to look again at the world around us and marvel at it all. It’s combination of physics, cosmology, geology and evolutionary sciences is like a terrific mixture of Carl Sagan’s Cosmos and David Attenborough’s Life on Earth. Ultimately though, Alpha offers readers something truly special, that beautiful feeling that comes simply from the sheer sense of wonder.
“Don’t ask me and don’t tell me. I was there.
It was a bang and it was big. I don’t know
what went before, I came out with it.
Think about that if you want my credentials.
Think about that, me, it, imagine it
as I recall it now, swinging in my spacetime hammock,
nibbling a moon or two, watching you.
What am I? You don’t know. It doesn’t matter.
I am the witness, I am not in the dock.
I love matter and I love anti-matter.
Listen to me, listen to my patter.
Oh what a day (if it was day) that was!
It was as if a fist had been holding fast
one dense packed particle too hot to keep
and the fingers had suddenly sprung open
and the burning coal, the radiant mechanism
had burst and scattered the seeds of everything,
out through what was now space, out
into the pulse of time, out, my masters,
out, my friends, so, like a darting shoal,
like a lion’s roar, like greyhounds released,
like blown dandelions, like Pandora’s box,
like a shaken cornucopia, like an ejaculation –
I was amazed at the beauty of it all,
those slowly cooling rosy clouds of gas,
wave upon wave of hydrogen and helium,
spirals and rings and knots of fire, silhouettes
of dust in towers, thunderheads, tornadoes;
and then the stars, and the blue glow of starlight
lapislazuliing the dust-grains –
I laughed, rolled like a ball, flew like a dragon,
zigzagged and dodged the clatter of meteorites
as they clumped and clashed and clustered into
worlds, into this best clutch of nine
whirled in the Corrievreckan of the Sun.
The universe had only just begun.
I’m off, my dears. My story’s still to run! ” Planet Wave, Edwin Morgan (excerpt)*
(* = apologies for such a lengthy quote, but Alpha put me in mind so much of the poetry of the great Edwin Morgan, who often showed a fascination for real science and for science fiction in his work, and I had to include the opening of his Planet Wave verse, which celebrates the creation of the universe, the world, people and life, much as Alpha does, although in very different ways. Carcanet have it in his collected poems, should you wish to read the full thing)

Here’s some vintage video of a conversation moderated by the late Magnus Manugsson, between Arthur C Clarke, Carl Sagan and Stephen Hawking, discussing life, god, science, the universe and everything… Let me just say that again: ARTHUR C CLARKE!! CARL SAGAN!!! STEPHEN HAWKING!!! Three of my heroes of science… Has sudden geekswoon… This was recorded in 1988 – strange to think of the four here (including the distinguished Magnus, who used come into my old bookstore from time to time and was always charming when he did), only Professor Hawking is still with us, a man who was told his illness would claim him when he was still just a young man.

Climate Changed: a Personal Journey Through the Science,
Climate change – it’s rarely been far from ours news reports over the last couple of decades, and increasingly so in recent years (freak once in century storms happen repeatedly, is it the climate changing and did we alter it?) and just this week we’ve seen a major UN report on expected climate change and the colossal cost to our civilisation if we don’t actually take action. And that action requires a lot more than people in Western nations changing to energy-saving lightbulbs and doing their recycling more – important though those are. And this month also sees Philippe Squarzoni’s approach to this huge scientific-political-ideological-cultural problem in comics form. In pretty weighty comics form, actually – this graphic science work weighs in at well over four hundred pages. This is not a quick read, nor should it be. We’ve seen an increasing number of graphic works tackling heavyweight subjects in recent years and making them very understandable and accessible to pretty much any reader, in the case of books like this even those with only their basic high school level of science learning.
This is not exactly jumping on the bandwagon though – for starters the book first came out in French from Delcourt a couple of years back, and secondly it is quite clear not just from the length but the detail Squarzoni goes into that this is something he has been working on for years. In fact early one we see that this large, complex work actually grew out of a previous bande dessinee Squarzoni had been working on, a book on French politics. As he researched and drew a section on the environment the author suddenly finds himself coming to a halt. When his partner asks him why, he replies it is because he is using phrases like ‘carbon neutral’ and ‘greenhouse gases’. Common phrases these days, we’re all familiar with those terms, right? His partner points this out. Yes, he responds, but what do they actually mean? I’m using these phrases lifted from bits of research and re-using them in my work but I don’t really know what they actually mean, what they involve and what they portend for the future.
And that is, perhaps, the crux of Climate Changed – many of us know these terms, we even use them sometimes in earnest pub discussions. But how much do most of us really know about the subjects these terms cover (Darryl Cunningham, you are excused this, we know you’ve researched it!)? I mean really understand, not just a vague knowledge assembled from the BBC website articles of the Guardian, but know the various aspects of climate change and how they relate to one another – and there is not just one topic here to get to grips with, this is a real multi-headed monster, a hydra of our own making, and we need, badly need, to understand the problems, and how they interact with one another, before we can even start to consider our response to them. Assuming, of course, we have the luxury of time to formulate a response. And also assuming humanity is wise enough to decide to take relevant action. And let’s be honest, recent events where agreed restrictions on targets like emissions being missed (after already being set fairly low to begin with) or even simply ignored by some nations, that latter part is not looking good right now.
Squarzoni, as you would expect, looks at the science behind climate studies and draws on numerous experts to discuss the observed changes, relating them to historical data gleaned painstakingly from sources such as deep ice cores and tree rings, to give centuries and even millennia of historical context. Because we know the Earth’s environment is always changing – it always has, it probably always will, ours is an incredibly dynamic bio system of overlapping, interacting elements: amount of sunlight reaching the surface, various gases at different altitudes in the atmosphere, currents in the air and the great oceans, the amount of ice at the poles or on glaciers, the amount of vegetation, venting from natural sources such as volcanoes… It’s a massively complex system with each component having effects on the other, which in turn cause further effects, from increased flooding to drought, even to the fabled “mini ice ages” (think of those pictures depicting the ‘frost fairs’ on a solidly frozen Thames). And this is before you factor in human activity…
“We’ve started things we cannot control…”
Despite the nay-sayers (and there are still many out there, often those with a large financial stake in the status quo of consume more, make more, want more) too many of these scientific studies clearly show large increases in output from human causes which are interacting with this incredibly complex environment’s variables – the charts leap following the industrial revolution really getting going in the 1800s and the post-WWII boom accelerates this at an astonishing speed. And it isn’t just as simple as more power stations pumping out CO2, or too many cars belching exhaust gases into the air – Squarzoni also draws on economic, social and cultural elements to this debate. Advertising imagery crops up numerous times, symbolic of our modern, Western, post-WWII urge to increasingly consume, tied to the cultural ethos of a capitalism that assumes we can endlessly consume, expand, consume more, expand – more production, more buying.
But we live in a finite system, there are only so many resources, and we are using them at an alarming rate. Not just the obvious resources such as fossil fuels being depleted (and increasingly so, with developing nations industrialising) but the simple, everyday items we all take for granted. Shiny new smartphone to replace the previous one – hey, it’s tiny, it’s just me, how much difference does that make? But multiply by the number being marketed and sold across the globe, the resources used to create them (rare minerals, metals), and the energy of mining those resources then that of the factory… And you get the picture. And don’t even get started on people who drive massive SUVs around city centres, the dirty looks Squarzoni gives repeatedly to a large Land Rover parked in the middle of Lyons speaks volumes!
“We continue to act like it’s nothing. And the worst thing is … it feels pretty good…”
But this isn’t some anti-capitalist diatribe – as Squarzoni points out neither he or any other person in the West has any desire to cut their use of resources from energy to affordable, plentiful food (and industrial scale agriculture is a major emitter of greenhouse gasses), losing our comfortable lifestyle where we have electricity on tap, central heating, easy transport, affordable range of clothing… He doesn’t really fancy cutting his environmental imprint to that of someone living a malnourished life in an underdeveloped nation without clean water, heating, power… And obviously none of us do. But if we can’t believe the lie of endless expansion and ever increasing consumption how do we square that circle of lowering our impact on greenhouse gases and resource scarcity with maintaining a decent standard of living? Especially as, increasingly from the 1980s on a small cadre of oligarchs and super-rich live a publicly indulgent, opulent lifestyle we’re all encouraged to want to emulate (work hard enough and anyone could be a billionaire in a mansion and yacht!). Plus why, he asks, should we ordinary folk decide to cut down on things like flights to cut pollution if the super-rich are swanning around in a Rolls Royce or a giant yacht?
And then there is the developing world – how do rich nations who created much of the pollution and resource consumption problem tell developing nations, no, sorry, you can’t come up to our standards, the planet won’t take it? He has to wrestle with this personal responsibility when offered a dream post, several months artist in residence in Thailand. But as he is in the middle of working on this book and researching the impact of things such as flying how can he in good conscience accept travelling there? He’d love to, but isn’t that hypocritical of him? But if he doesn’t go, but the guy down the street continues to run round town in his gas-guzzling SUV, what different has his personal sacrifice made? And, as his partner asks him, does that mean that he will never fly again? Does that mean the places they’d love to see together will be off-limits for them? What about green technologies? Are some good or just a bandwagon that some big companies (who have given more than their share of pollutants) a new, image-friendly ‘green’ marketplace to exploit? From large corporate installations to the personal, such as solar panels or wind turbines on the roof of our homes, which are actually effective, which will help do a bit to reduce our impact, and which are really just a salve to our conscience?
It’s one of the aspects of this book that makes it so accessible and easily understandable – for all the expert talking heads (which are frequent, but while slightly repetitive as a method, it is nonetheless a good way of getting information from expert sources across to the reader) talking about the Big Picture – what government, massive corporations and trans-global organisations such as the UN are trying to do (or frequently failing to do, depressingly), the sheer array of different experts required to make sense of it all (climatologists, industrial experts, meteorologists, geologists, disaster relief experts, economic experts and more) he continually comes back to the personal level, both from the personal responsibility side of things (what can we do individually? How do we encourage others to do the same so small change become large differences? Why should we if others don’t?) but it also reminds you constantly that the author himself is not a scientist, that he’s coming to this subject himself as an individual and realising from his research that, just as some of the experts are arguing, this is a subject that requires individual responses and changes in lifestyle, but also collective – this is a global problem and no nation will escape effects.
Even if you are lucky enough to live in a country where, say, temperature rises from greenhouse gases are mitigated because actually it makes your region a bit nicer to live in during winter months, you will still suffer because resources from oil to container vessels full of food come in from all around the world. And some of those areas may suddenly stop being so productive. Or may even be under rising waters. And then there are those rising waters – with a huge chunk of our global population (including massive Western cities of millions) right by the coast there will be problems. Perhaps catastrophes (imagine millions being displaced as environmental refugees, both in the developing world and even in the rich, Western nations – consider the thousands of poorer citizens left behind to face the waters in New Orleans after Katrina, but on an even larger scale).
On the art front there are, as you might expect perhaps for a thick tome dealing with science, a lot of graphs, and a lot of ‘talking heads’ as a series of experts from different fields – climatologists, energy experts, economists and more – to deliver large sections of information. But to stop these being too repetitive he also uses a variety of other visual tricks – his obvious love of cinema comes in handy, with frequent visual references to the iconography of film, for instance, and advertising imagery is used regularly, while he keeps grounding this vast subject in the personal with scenes from his own life with his partner and dog, as well as flashbacks to childhood (comparing his journey through life to the relentless change of the world). This also leads to a touching scene further in, as the years go past and their trusted old dog passes away we see later scenes where Squarzoni goes walking in the snow, accompanied by a ‘ghost’ dog, just the outline of his old pal by his side, not actually drawn in detail, the memory of his dog by his side. His walks through the French countryside include some quite lovely large scenes – we may be doing something bad to our environment, but it is still a quite beautiful world, he is pointing out. And in a book where there are many small, close up panels of people talking or detailed charts and graphs it’s nice to be able to breathe in the fresh air of a large, beautifully rendered scene of lakes and mountains.
It can be quite overwhelming reading – to be honest, despite finding it utterly fascinating and compelling I found it best to limit myself and read it in chunks (the layout of sections actually made this quite a suitable way to approach the book), partly not to simply overload my brain with concepts and figures and arguments, but partly also so I could allow myself time to stop and consider what I was reading. And despite what you may think, it isn’t entirely negative or doom-laden (although there is a strong pessimistic bent) – Squarzoni doesn’t restrict himself to covering everything we’re doing wrong as a species, he marshals many of those same ‘talking heads’ of his expert panel to discuss possible changes. All are adamant we have to change, and the science backs this up – despite some very shoddy media reports – as he points out when some opponents used media claims of dissent between scientists to fuel doubt about climate change a study of a decade of appropriate peer-reviewed scientific journals revealed no such disagreement, compared to about half of articles written by journalists which tried to convey there was doubt about human-made climate change – draw your own conclusions from that. And all point out that such changes are best managed incrementally – none of them want to tip the world back into economic chaos by suddenly imposing major changes without planning viable alternatives, and the quicker we start changing and adapting then the less severe those changes have to be (as opposed to head in the sand, wait till last minute then have to take radical surgery instead of holistic long term treatment approach). And all agree that such change can’t simply be forced, the democratic principle has to be used, people engaged in the debate, informed and give consent (and indeed to pressure) to their political leadership for changes.
It’s a fascinating, thought-provoking work, well-researched (coming with a good bibliography and list of various experts quoted and other resources for learning more), and the graphical approach makes the task of assimilating the mass of complex material much simpler for the reader. Squarzoni is also to be commended for taking in the large range of industrial, economic, social and cultural aspects to climate change and relating them to one another, in addition to the perhaps more obvious issues of just what sorts of waste we’ve pumped out relentlessly into our own biosphere without thinking about what it was doing. This isn’t a single problem, it’s a series of multiple but interconnected problems, some exacerbated by natural causes, but most from human causes which many simply don’t think about much, beyond the afore-mentioned changing to energy efficient bulbs. But as one expert points out in the book, the Earth has it’s own timetable – change is happening and most consider we’ve gone beyond the point where we can stop even more change coming. But we can adapt to it, we can limit the changes, manage them better, if we’re informed and able to make those decisions (and the drive to see them through – actual action, not just fine speeches from politicians or ads telling us how much giant oil companies care about the environment). And as with many problems, reading about them is a fairly good place to start… Don’t be put off by the size of the book or the heavyweight subject matter – as I said Squarzoni does a remarkable job in putting across the subject and also personalising it (it also arrives bearing plaudits and awards from the European scene), and let’s face it, as arguments erupt already over this new UN climate report out this week, we could all do with being more informed on a subject that affects every single person on the planet.
this review was originally penned for the Forbidden Planet Blog
Space has always fascinated me, perhaps not surprisingly as I was born at the peak of the Apollo programme, just a couple of years before Neil Armstrong’s giant leap on the Moon. I had my little astronaut suit to play in, repeats of the original Star Trek, Doctor Who, UFO, numerous other Gerry Anderson shows – space and an optimism in the future and in our ability to learn to use our own brains and science to better humanity were popular topics (sadly so much more pessimistic today for many). I was a child of the Space Age and then grew up in the early Information Age, I had a stack of astronomy books on my shelves even as a kid (reader then, as now). And then there was Cosmos and Carl Sagan on the television. I read and read, by the time I was 9 or 10 I could tell you the difference between a Gemini and a Soyuz and an Apollo capsule, I knew who Kepler was and how his mathematics shaped our understanding of our solar system.
I loved my books, but in Cosmos I could see it all – a history of science here on Earth and how it applied to our expanding knowledge of the universe itself, not just showing fascinating glimpses of distant creation, but putting it into a context of accumulated knowledge. I didn’t realise that aspect of it until I was much older, but subliminally the message was received and somewhere inside my young brain, absorbed and applied and forever after I have taken simple delight and pleasure in finding links between pieces of knowledge, that wonderful moment when you realise that something you are reading or watching relates to some other subject you read previously, connection and connection and connection. I still take pleasure when that happens today, and it was a lesson Sagan taught in the original Cosmos, that knowledge is one thing, but the ability to step back, place that piece of knowledge into context, was even more important, because then you start to assemble the jigsaw that shows The Big Picture. We never actually finish that particular jigsaw, because none of us is omniscient, but there’s so much pleasure to be had from assembling and connecting those pieces…
The original Cosmos also helped me humiliate an utter prig of a senior at my school, who tried to make me and my friend feel small and stupid. Back when there was a single BBC Micro for the whole school we were busy programming on it when this senior barged in with a friend, demanding we stop and they get to use it because their science teacher had an “important” programme that “we wouldn’t understand”. I asked what it was, and in a very condescending tone he told us it was to do with Kepler’s laws and we wouldn’t know anything about that. I proceeded to outline the main points of Kepler’s laws and observations and place them in their historical context for good measure. I would only be about eleven or twelve, he was about fifteen. I watched him deflate and become utterly humiliated as it was clear to all in the room that Mr Superior knew less about this subject than a boy did. Thanks to Sagan and Cosmos, where I learned of it then, me being me, I had followed this up by reading more about it. Learning is our friend. And sometimes we can use it in interesting ways, to beat an intellectual bully. Satisfying in itself, and also taught me a lesson too – there’s always someone who knows more than you do…
Sagan’s books and his Cosmos series had a huge influence on me. I think his series and the programmes of the great Jacques Cousteau taught young me an enormous amount about science and what Sagan called “the awesome machinery of nature.” My brain was never terribly good with maths, so studying science at university was never likely, my thoughts were more wired to the arts and language, and I have no regrets over that because I am forever in love with words, but they, and my piles of related books, left me with a huge fascination for an and appreciation of science and learning. And space exploration and astronomy especially, but again there’s that thing about learning being linked – learning about theories of how the other planets became the way they are prompted me to read some geology to understand this better. As a kid I also loved dinosaurs (which wee boy doesn’t?) and of course that linked with geology, which also lead into theories of evolution, which in turn lead to books about why it is humans can think, have language, create abstract thought, the very faculties that allowed for astonishing things like space exploration. There it is again, link, after link after link, all adding layers of context to what was learned.
And so this evening the much anticipated new Cosmos made its UK debut, with an introduction by President Obama, no less. Of course dear old Carl has been gone for a number of years now, but his influence is still felt, from his own opening narration and choice of similar location to that he used for his original introduction to the use of the ‘spaceship of the imagination’. And the new presenter, Neil deGrasse Tyson also embodies another link to Sagan – a joyfully personal one too, as he recounts at one point how as a seventeen year old student Sagan had invited him to visit. He arrived during heavy snow and Sagan talked to him, showed him his lab and offices at Cornell and presented him with a signed copy of one of his books (which he still has), an encounter which enthused the young man not only to a career in science but to emulate his role model in communicating science to a wider audience, to let everyone share in the knowledge and consider its implications and possibilities, which is important given how such matters often affect all of civilisation.
And so the new show’s first episode this evening… The format is similar to the classic Cosmos, the mixture of astronomy but interspersed with history, both human history of ideas and understanding and the deeper history of our own world, solar system, galaxy and universe. Again, context, links, without which facts don’t mean much. Of course the graphics are vastly superior to the effects the 1980 show could ever hope to create (although back then I still remember marveling at them). But the most important quality, more important than the scientific facts, the history, the learning, was something Sagan gave me in the original, Cousteau did with his shows, Arthur C Clarke did with his books – and that is the quality of sense of wonder. Simple as that – a sense of wonder that makes you feel like a bright eyed child again staring at the stars and imagining and dreaming. And yes, the new show had that sense of wonder.
You can read a short interview with the new Cosmos presenter Neil deGrasse Tyson on the Nat Geo site.
This is simply stunning, brief though it is, a timelapse of footage shot of our world rotating below the International Space Station (ISS), all shot in beautifully crisp HD, creating some wonderfully sharp, clear images of our planet from several dozens miles above the atmosphere. Best viewing experience is to select the fullscreen option and just glory in it for a few brief moments…
Directed Alfonso Cuarón
Starring Sandra Bullock, George Clooney
I’ve been eager to see Gravity for some time – Alfonso Cuarón’s take on PD James novel The Children of Men was a remarkable and powerful movie. This, originally, was to be his ‘quick’ movie after that long slog, but ended up taking several years instead, not least because they had to invent whole new ways of shooting to create the remarkable visual effects. Creating the effect that a person or a ship is in space is not new, of course, it’s been done with varying degrees of success for decades on the big screen, from the realistic approach of 2001 to the scientifically silly but visually wonderful style of Star Wars. Gravity follows more in the realistic mode of 2001 – no deep bass rumbles of mighty ships in the void (where there isn’t any atmosphere to transmit sound) and no sudden and graceful movements of winged craft that fly like planes (even though that is not how you maneuver in space), instead the only sound is inside your helmet or radio, movement is in line with Newton’s laws and the way a body travels in a gravity free, airless environment.
What it does differently from 2001 and other films which tried to portray space exploration as it really is though, is the depiction of being in a zero-gee environment. Cuarón and his team had to really battle to come up with filming systems to allow them to make their actors look like they truly are in a gravity free environment, and ye celluloid gods but it paid off. In fact, and I say this as someone who has been fascinated by space exploration since he was a very small boy, studied it, read about, imagined it, this paid off so well that you could be forgiven for thinking it was actually shot on location in Earth orbit. Yes, it really is that realistic looking. And it is also utterly ravishing, visually, right from an opening shot of a glowing Earth below a team of astronauts from a Shuttle working on the Hubble Space Telescope. Bullock’s specialist, a scientist brought into NASA to work on this particular upgrade because of her technical skills but not really an astronaut (apart from basic training), while Clooney’s veteran astronaut on his final flight is happily trying out a new design of MMU (Maned Maneuvering Unit – a jetpack for space, effectively) and flitting around the team. The glowing Earth below them fills the cinema screen and is simply beautiful, awesome in the proper use of the word.
But while the visual aspect of Gravity is remarkable and stunning (even the 3D, something I generally dislike in live action films, is excellent and worth the usual eye strain and headache) this isn’t just an effect fest, there is a story here and it is one which is incredibly tense and indeed intense, seriously gripping the arms of your chair stuff, right the way through. When Mission Control calls a warning to the team that a satellite has been destroyed and the debris is sweeping around the orbit towards them events rapidly spiral out of control into a desperate, against the odds attempt at survival.
And survival in an environment no human – no creature on our planet at all – evolved to survive in. It’s a deadly environment that we’ve somehow pushed ourselves and our technology to allow us to live and work in over the last half decade (and it’s worth remembering that in thousands of years of human history it is only a few dozen people over the last sixty years who have gone into space). And it anything goes wrong it can be fatal so very, horribly quickly. Even tiny pieces of debris, even just a bolt, travelling at twenty thousand miles and hour will have such kinetic force it can tear through a ship or a space station like an anti-tank round. And all of a sudden an intricate ship or station, assembled from so many precise components and painstakingly engineered and constructed to be just right to support human life in this environment is turned into Swiss cheese…
I won’t ruin it for you by expanding any further on how it develops from this accident. Suffice to say it is edge of the seat stuff, beautifully depicted, while the interaction between Bullock’s damaged scientist and Clooney’s veteran of the space programme, even in desperate straits, is perfectly handled (Clooney projects that image most of us have of the calm, unflappable NASA old school astronaut who takes the most catastrophic failures in his stride). This may be vast scale, big-screen, effects-laden storytelling, but it does not neglect either story or character and I found it profoundly satisfying on the emotional level as well as the spectacle. There are some nice nods to other iconic moments from space films tucked away in among the tense moments – a scene where Bullock floats in an airlock, shimmying out of her space suit recalls Barbarella, Bullock in vest and shorts in the space station reminds me of Ripley in the shuttle at the end of Alien, Bullock again floating, exhausted, in an airlock, the sunrise from space glowing through the window port as he floats in zero gee, curling up almost foetal after surviving one part of her ordeal, the cords around her like an umbilical coil, making her seem at the same time both childlike, a newborn and at the same time recalls the ‘star child’ from 2001 and the transformational power of such experiences and travel. It’s gripping right to the very last and as I said the visuals are simply breath-taking – this is one you want to see on the big screen, not on DVD later on, watch it on a big cinema screen and let yourself be drawn into it until you feel you’re there, floating above the world. An utterly remarkable piece of film-making.
And I have to add, on a personal note, those visuals played right into my life-long fascination with space travel; that screen-filling vista of the Earth revolving made my pulse race, just as it always has since I was a kid, at the thought of going into space. I had the same feeling watching In the Shadow of the Moon a few years ago; those Saturn V rockets lit up and my pulse went with them, the same excitement and longing I’ve had since I was five years old, in my little astronaut playsuit and helmet, sitting in an empty box for a spaceship, with an imagination as big as the universe. And even after watching a film like this showing the dangers I know that if I were offered the chance I would go in a heartbeat, that it’s the trip I have always wanted to make since I was that wee boy in his astronaut suit, playing and dreaming; I’m literally a child of the space age, born at the peak of the Apollo programme, and I’m forever disappointed that I’ll almost certainly never get to experience it first hand…
An infinitesimal dot in a vast space, containing, as the great Carl Sagan once said of another famous image from our exploration of space, the Pale Blue Dot image, every single person you ever knew, your mother, father, brother, your grandfather, his father back to the earliest proto human, every cat, dog, fish, bird, every beggar and king, every famous musician, every humble artisan, all lived on that dot. That’s home. Now Cassini sends us this spectacular image from Saturn, the crown jewel of the solar system, the Earth, a bright, blue dot (arrowed in the pic) glowing in the vast distance, millions of miles away while the magnificent rings of Saturn wheel above.
Every person, everything we’ve ever done is on that dot, from the first single celled creatures through the great dinosaurs to us, all contained inside that glowing dot. And yet look at this picture, look at how far we can reach, further than anyone in thousands of years of human history – look at how far we can reach when we put out efforts and those big brains evolution gave us to some wonderful effort instead of squabbling and fighting among ourselves on that same small dot. When we’re not doing that, this is the kind of thing we can accomplish, and it is magnificent. A little reminder as we see endless bad news of wars, disasters, economic ruin and more every night on the news that actually we are remarkable, our species built this clever probe, worked out a complex flight path around celestial bodies at huge speed, swinging around gravity wells and did so with such precision it can send us back images of our own world as seen from the rings of Saturn and we can share it at almost the speed of light through fiber optic networks of computers across that little globe, instantly.
“The Earth is the shore of the cosmic ocean. Recently we’ve waded a little way out, and the water seems inviting...” Carl Sagan.
During the epic Voyager missions, after one of those innovative little mechanical explorers had finished with its primary mission to give us our most astonishing close up encounters with the most distant worlds in our solar system in a detail that Galileo and Copernicus could never have dreamed possible, it was re-tasked and reprogrammed to turn around to look back into our solar system from the cold, dark edge of our own little stellar neighbourhood. The late, great Carl Sagan was one of those who campaigned for this to happen – no small feat given the codes to reprogramme the distant probe would take hours to reach it even travelling at the light speed of radio waves, so far was it from home now, and there was no true scientific knowledge to be gained from this move.
Sagan, however, always understood that science has to appeal to both the heart as well as the head, emotion and intellect, and be able to make everyone grasp why it was important to us. The spacecraft was turned and took what is now known as the family portrait, a view of most of the planets in our solar system, a perspective no-one in the entire history of humanity had ever beheld before, a real “going where no-one had gone before” moment. In that family portrait is a pale, blue dot, not even an entire pixel in size – our world, the Earth. As Sagan put it, everything any of us has ever known, every person we have read of, every person who built a monument we’ve gazed at, everyone we have ever loved and all those who came before them, right back to the emergence of our ancestors out of ancient Africa’s cradle to start out human journey, every one of them, peasant and king alike, lived on that tiny dot. Joel Somerfield’s animation is very short but celebrates that moment, using the words of Sagan, a moment when emotion and science, heart and intellect, gave our species a new perspective on the majesty of creation and our own place in it, just a tiny mote floating in the glow of the sun, miniscule in astronomical terms, fragile, but never, ever unimportant, but a wonder in a sea of wonders, a haven of spectacularly diverse life. Our home.
