"Our world, warm, comfortable, familiar but when we look up, we wonder:" "Do we occupy a special place in the cosmos?" "Or are we merely a celestial footnote" "Is the universe welcoming or hostile?" "We could stand here forever, wondering" "Or we could leave home on the ultimate adventure" "To discover wonders" "Confront horrors" "Beautiful new worlds" "Malevolent dark forces" "The Beginning of time." "The moment of creation." "Would we have the courage to see it through?" "Or would we run for home?" "There's only one way to find out" "Our journey through time and space begins with a single step." "At the edge of space, only 60 miles up just an hour's drive from home" "Down there, life continues." "The traffic is awful, stocks go on trading and Star Trek is still showing" "When we return home, if we return home will it be the same?" "Will we be the same?" "We have to leave all this behind" "To dip out toes into the vast dark ocean" "On to the Moon." "Dozens of astronauts have come this way before us" "Twelve walked on the moon itself" "Just a quarter of a million miles from home." "Three days by spacecraft" "Barren." "Desolate." "It's like a deserted battlefield" "But oddly familiar." "So close, we've barely left home" "Neil Armstrong's first footprints." "Looks like they were made yesterday" "There's no air to change them." "They could survive for millions of years" "Maybe longer than us." "Our time is limited" "We need to take our own giant leap" "One million miles, 5 million, 20 million miles." "We're far beyond where any human has ever ventured" "Out of the darkness, a friendly face" "The goddess of love, Venus." "The morning star." "The evening star." "She can welcome the new day in the east say good night in the west" "A sister to our planet she's about the same size and gravity as Earth." "We should be safe here" "But the Venus Express space probe is setting off alarms" "It's telling us, these dazzling clouds, they're made of deadly sulfuric acid" "The atmosphere is choking with carbon dioxide" "Never expected this Venus is one angry goddess." "The air is noxious, the pressure unbearable." "And it's hot, approaching 900 degrees" "Stick around and we'd be corroded suffocated, crushed and baked" "Nothing can survive here." "Not even this Soviet robotic probe." "Its heavy armor's been trashed by the extreme atmosphere." "So lovely from Earth, up close, this goddess is hideous" "She's the sister from hell." "Pockmarked by thousands of volcanoes" "All that carbon dioxide is trapping the Sun's heat." "Venus is burning up." "It's global warming gone wild" "Before it took hold, maybe Venus was beautiful, calm more like her sister planet, Earth." "So this could be Earth's future" "Where are the twinkling stars?" "The beautiful spheres gliding through space?" "Maybe we shouldn't be out here, maybe we should turn back" "But there's something about the Sun, something hypnotic, like the Medusa" "Too terrible to look at, too powerful to resist" "Luring us onward on, like a moth to a flame." "Wait, there's something else, obscured by the sun" "It must be Mercury." "Get too close to the sun, this is what happens." "Temperatures swing wildly here" "At night, it's minus 275 degrees..." "Burnt then frozen." "The MESSENGER space probe is telling us something strange." "For its size, Mercury has a powerful gravitational pull." "It's a huge ball of iron, covered with a thin veneer of rock" "The core of what was once a much larger planet." "So where's the rest of it?" "Maybe a stray planet slammed into Mercury blasting away its outer layers in a deadly game of cosmic pinball" "Whole worlds on the loose careening wildly across the cosmos destroying anything in their path" "And we're in the middle of it" "Vulnerable, exposed, small" "Everything is telling us to turn back." "But who could defy this?" "The Sun in all its mesmerizing splendor" "Our light, our lives everything we do is controlled by the Sun" "Depends on it" "It's the Greek god Helios driving his chariot across the sky" "The Egyptian god Ra reborn every day" "The summer solstice sun rising at Stonehenge."

"we've got the real thing" "We see it every day, a familiar face in our sky" "Now, up close, it's unrecognizable." "A turbulent sea of incandescent gas" "The thermometer pushes 10,000 degrees can't imagine how hot the core is, could be tens of millions of degrees" "Hot enough to transform millions of tons of matter into energy every second" "More than all the energy ever made by mankind" "Dwarfing the power of all the nuclear weapons on Earth." "Back home, we use this energy for light and heat" "But up close, there's nothing comforting about the Sun." "Its electrical and magnetic forces erupt in giant molten gas loops." "Some are larger than a dozen Earths" "More powerful than 10 million volcanoes." "And when they burst through they expose cooler layers below making sunspots." "A fraction cooler than their surrounding, sunspots look black But they're hotter than anything on Earth." "And massive up to 20 times the size of Earth." "But one day, all this will stop" "The Sun's fuel will be spent." "And when it dies, the Earth will follow" "This god creates life, destroys it and demands we keep out distance" "This comet strayed too close" "The Sun's heat is boiling it away creating a tail that stretches for millions of miles." "It's freezing in here." "There's no doubt where this comet's from, the icy wastes of deep space" "But all this steam and geysers and dust it's the Sun again, melting the comet's frozen heart." "Strange." "A kind of vast, dirty snowball, covered in grimy tar" "Tiny grains of what looks like organic material preserved on ice, since who knows when maybe even the beginning of the solar system." "Say a comet like this crashed into the young Earth billions of years ago." "Maybe it delivered organic material and water the raw ingredients of life" "It may even have sown the seeds of life on Earth that evolved into you and me" "But say it crashed into the Earth now" "Think of the dinosaurs, wiped out by a comet or asteroid strike" "It's only a question of time." "Eventually, one day, we'll go the way of the dinosaurs" "If life on Earth was wiped out, we'd be stuck out here homeless, adrift in a hostile universe" "We'd need to find another home" "Among the millions, billions of planets there must be one that's not too hot, not too cold, with air, sunlight, water where, like Goldilocks, we could comfortably live" "The red planet" "Unmistakably Mars." "For centuries, we've looked to Mars for company for signs of life" "Could there be extraterrestrial life here?" "Are we ready to rewrite the history books, to tear up the science books to turn our world upside down?" "What happens next could change everything" "Mars is the planet that most captures our imagination." "Think of B-movies, sci-fi comics, what follows?" "Martians?" "It's all just fiction, right?" "But what it there really is something here?" "Hard to imagine, though." "Up close, this is a dead planet" "The activity that makes the Earth livable shut down millions of years ago here" "Red and dead" "Mars is a giant fossil." "Wait." "Something is alive" "A dust devil, a big one" "Bigger than the biggest twisters back home." "There's wind here" "And where there's wind, there's air" "Could that air sustain extraterrestrial life?" "It's too thin tor us to breathe." "And there's no ozone layer" "Nothing to protect us against the Sun's ultraviolet rays." "There is water But frigid temperatures keep it in a constant deep freeze" "It's hard to believe anything could live here" "Back on Earth, there are creatures that survive in extreme cold, heat even in the deepest ocean trenches" "It's as though life is a virus." "It adapts, spreads" "Maybe that's what we're doing right now carrying the virus of life across the universe." "Even in the most extreme conditions life usually finds a way." "But on a dead planet?" "With no way to replenish its soil, no heat to melt its frozen water?" "All this dust, it's hard to see where we're going" "Olympus Mons, named after the home of the Greek gods" "A vast ancient volcano." "Three times higher than Everest." "There's no sign of activity." "Since its discovery in the 1970s, it's been declared extinct" "Hang on." "These look like lava flows." "But any sign of lava should be long gone, obliterated by meteorite craters" "Unless, this monster isn't dead, just sleeping" "There could be magma flowing beneath the crust right now building up, waiting to be unleashed" "Volcanic activity could be melting frozen water in the soil pumping gases into the atmosphere, recycling minerals and nutrients" "Creating all the conditions needed for life" "This makes the Grand canyon look like a crack in the sidewalk" "Endless desolation so vast it would stretch all the way across North America." "But here, signs of activity, erosion, and what looks like dried up river beds" "Maybe volcanic activity melted ice in the soil sending water gushing through this canyon." "Underground volcanoes could still be melting ice, creating water" "And where there's water, there could be life" "The hunt for life is spearheaded by this humble fellow the NASA rover, Opportunity." "It's finding evidence that these barren plains were once ancient lakes or oceans that could have harbored life" "Look at those gullies." "Probes orbiting Mars keep spotting new ones." "More proof that Mars is alive and kicking that water is flowing beneath its surface right now" "Water that could be sustaining Martian life" "Now, all we have to do is find it" "Maybe we've already found what we're looking for on Earth" "Some think that life started here and then migrated to Earth" "An asteroid impact could've blasted fragments of Mars and onto the young Earth where they sowed the seeds of life" "No wonder we find Mars fascinating, this could be our ancestral home" "It could be we are all Martians" "The Mars we thought we knew is gone replaced by this new, active, changing planet." "And if we don't know Mars, our next door neighbor how can we even imagine what surprises lie ahead" "Our compass points across the cosmos back in time 14 billion years to the moment of creation." "This is getting scary." "It's like being inside a giant video game" "But these are all too real." "Asteroids, some of them hundreds of miles wide" "This one must be about 20 miles long." "And there, perched on it, a space probe." "Can't have been easy parking on an asteroid traveling at 50,000 miles an hour." "It's a lot of effort just to investigate some rubble." "Rubble that regularly collides breaks up and rains down on Earth as meteorites." "Our ancestors saw shooting stars as magical omens." "And they were right" "Rubble like this came together to make the planets including our own" "Pretty magical." "By dating the meteorites found on Earth we can tell the planets were born 4.6 billion years ago." "These are the birth certificates of our solar system." "For some reason, these rocks didn't form into a planet" "Something must have stopped them" "Something powerful." "Jupiter." "What a monster" "At least a thousand time bigger than Earth so vast you could fit all the other planets inside it" "Something this massive dominates its neighbors" "Its gravity is pulling the asteroids apart" "And it's breathtaking" "But this beauty is a beast." "It's almost all gas." "Land here and we'd sink straight through its layers into oblivion." "And Jupiter's good looks?" "The product of ferocious violence" "It's spinning at an incredible rate whipping up winds to hundreds of miles an hour contorting the clouds into stripes eddies, whirlpools and this, the legendary Great Red Spot" "The biggest, most violent storm in the solar system." "At least three times the size of Earth, it's been raging for over 300 years" "All these churning clouds must have sparked an electrical storm" "Just one bolt is 10,000 times more intense than any at home." "Looks like the safest place to see Jupiter is from a distance" "Up there at the poles those dancing lights, they're like the auroras back home." "But the Geiger counter is going wild" "Even these are deadly, generated by lethal radiation" "Out here, nothing is what it seems." "The universe is full of terrors, traps." "Maybe this is a safe haven, the multi-colored moon, Io" "Wrong" "Very wrong." "Those brilliant colors are molten rock, volcanoes spewing lava." "Our journey across the universe is turning into a struggle for survival" "We've got to hope that if we outlast the dangers we'll be rewarded by wonders beyond imagination" "Four hundred million miles from Earth flying a commercial airliner here would take nearly a century" "What a weird looking place and yet, strangely familiar" "A bit like the Arctic, with all that ice, all those ridges and cracks" "It's Jupiter's moon, Europa." "And maybe, like the Arctic, this ice is floating on water, liquid water" "But we're half a billion miles from the Sun." "Surely, Europa is frozen solid" "Unless, Jupiter's gravity is creating friction deep inside heating the ice into water, allowing life to develop in the water beneath its frozen crust." "We might be feet away from aliens" "From a whole ecosystem of microbes, crustaceans, maybe even squid" "The only thing between us and the possibility of alien life this layer of ice." "But until we send a spacecraft to drill here Europa's secrets will remain beyond reach" "It's captivated our imaginations, haunted our dreams" "And here it is, spinning before our eyes" "Saturn." "Named for the Roman god who reigned over an golden age of peace and harmony" "This planet's a giant ball of gas, so light it would float on water" "Its spectacular rings would stretch almost from Earth to the Moon." "There's the Cassini orbiter" "It's picking up ghostly radio emissions" "Probably generated by auroras around Saturn's poles" "This is the real music of the spheres." "Cassini's telling us where these rings came from." "They're the remnants of a moon shattered by Saturn's gravitational pull" "Incomparable beauty from total destruction" "Billions of shards of ice" "Some as small as ice cubes, others the size of houses." "They collide, break apart, reassemble" "It's like a snapshot of our early solar system as dust and gas orbited the newly born Sun and gravity worked this magic pulling the lumps together until from space trash like this, our home emerged" "We could stay here forever" "But there's so much further to go, so much more to see." "Like this moon wrapped in thick clouds, Titan." "There's an atmosphere down here" "There's wind, rain, even seasons" "Rivers, lakes and oceans" "It looks so familiar, so similar to Earth." "But that's not water, it's liquid natural gas" "Hundreds of times more natural gas than all the Earth's oil and gas reserves" "Maybe, one day, we'll use this energy to fuel a colony." "Assuming there isn't life here already" "The Huygens space probe is here to find out" "It's telling us there's organic material in the soil." "But it's so cold, minus 300 degrees" "There's no way life could develop" "Unless Titan warms up." "The Sun is supposed to get hotter" "When it does maybe life will spring up here just like it did on Earth" "And as the Earth gets too hot for us, maybe we'll move to Titan." "One day, we might call this distant land home" "Home." "We're at least 700 million miles away now." "After this we lose visual contact with Earth." "We're standing on a cliff" "Looking out over a great chasm that stretches to the beginning of time." "Do we have the courage to jump?" "We're in the solar system's outer reaches." "Unseen from Earth, unknown for most of history" "It's like diving into the depths of the ocean" "Those rings make it look like Uranus has been tilted off its axis toppled over by a stray planet" "It's eerie out here."

"Something else must be creating these ferocious winds" "But what?" "We know very little about our own solar system." "After all those balls of gas a solid moon Triton." "Solid but not stable" "Just look at those geysers cosmic smokestacks pumping out strange soot." "And this moon is revolving around Neptune in the opposite direction of the planet's spin." "A cosmic battle of wills that this angry moon is destined to lose" "Neptune's massive gravity is pulling on Triton." "Slowing it down, reeling it in" "One day, it will be ripped apart by Neptune" "And that's it" "No more moons, no more planets in our solar system." "It's getting colder, we're getting further from the Sun slipping from the grip of its gravitational tentacles." "But this isn't a void" "It's teeming with frozen rocks." "Like Pluto."

"A greeting record in different languages" "And a map showing how to find our home solar system" "The great physicist, Stephen Hawking thinks it was a mistake to roll out the welcome mat." "After all, if you're in the jungle, is it wise to call out?" "These comets look like the ones we saw earlier." "There's a theory that the raw materials for life began out here on a rock like this until something dislodged it sending it hurting towards the Earth" "And seeding all this ice, maybe comets carried water to Earth too" "The water in the oceans, in your body all from this distant celestial ice machine." "We're 5 million, million, that's 5 trillion miles from home." "But this is still only a baby step." "Ahead, trillions of miles, billions of stars."

"So bright that when light from the explosion reached Earth 20 years ago it was visible to the naked eye" "And so violent, it triggered a string of nuclear reactions forcing atoms together, creating new elements gold, silver, platinum, blasting them out into space." "The gold in the ring on you finger was forged in a massive supernova like this trillions of miles away, billions of years ago." "Before we left home, the universe seemed desperate something out there, up in the sky." "But now we know better." "We are the universe, and it is within us" "It's comforting to remember as we venture through this abyss." "Further and further" "Faster and faster" "The Andromeda Galaxy two and half million light years away" "It's racing through space everything blown apart, like shrapnel in an explosion." "We're seeing this galaxy as it was when our ape-like ancestors first walked on the African plains" "Further through space, and further back in time" "Hold on." "This doesn't look right" "A whole galaxy exploding?" "The only thing large enough to cause an explosion on this scale is another galaxy." "It looks like the end of the world" "But this galaxy won't die, it will be reborn." "A new shape, perhaps even new stars as dust and gas collide, creating friction, shockwaves triggering the birth of stars." "There's order in this chaos, a pattern behind the infinite variety an endless cycle of birth and death, creation and destruction" "It's a pattern woven through the vast fabric of space that binds each of these galaxies" "There are billions of galaxies each with billions, even trillions of stars." "Maybe more stars than there are grains of sand on all the beaches on Earth." "We're finally beginning to see the big picture and it's grander than we ever imagined" "This galaxy, the huge Pinwheel Galaxy is so far from Earth that if we send a message home now it will take 27 million years to get there." "Who knows whether our species, our planet will still be around to receive it?" "We travel on, back through time" "Past the point where the dinosaurs were wiped out past the moment where the first creatures crawled onto land" "Two billion light years from home." "Closing in on the edge of the universe" "Going back to the beginning of time" "This isn't a galaxy." "It's brighter than a hundred galaxies" "A blinding beam of energy surging for trillions of miles." "Something this big, this bright, must be incredibly powerful" "Experience tells us, out here, power equals danger" "It looks like a quasar, the deadliest thing in the universe" "Our journey could be over" "The deadliest, most powerful thing in the universe." "A quasar." "A swirling cauldron of superheated gas" "This beast has a heart of darkness, a super-massive black hole as heavy as a billion suns." "It's ripping apart whole stars devouring them until they're nothing lost forever from the visible universe" "We think, we hope, we pray we've seen the worst the universe can throw at us." "But no one can know what lies ahead" "We'll need to go further, go faster" "Eight billion light years from home." "More galaxies, but these look different" "Ragged, small, close together" "We're so far back in time we're seeing these galaxies as they were before the Earth was born" "They're still young, still growing." "We're getting close to where and how it all began" "Look at the galaxies now." "They're more like primitive plankton floating in a vast dark ocean" "Clouds of dust and gas dancing, twirling, merging to make embryonic galaxies." "They're disappearing" "We've gone back before the stars were born into a cosmic dark age" "And before that, light, the afterglow from the massive explosion that created the known universe" "This is it." "We've made it" "The edge of universe 80 Billion trillion miles from home 13 and a half billion years ago" "The very instant of the Big Bang the most violent, most creative moment in history." "Everything that's ever happened follows from this moment." "Every religion, every culture, has pondered it" "But we still don't known what sparked this act of creation or why" "This is where our journey ends and the universe begins" "An infinitely hot, small, dense point erupts" "Creating space, time, matter, our universe itself." "First, it's the size of a subatomic particle." "The tiniest traction of a second later it's big enough to hold in the palm of your hand" "Moments later, it's the size of the Earth." "Today, the light from the Big Bang is still spreading out" "You can hear it as a radio hiss" "See it as television static." "All the wonders we've seen on our journey are sparks flying out from the Big Bang." "Galaxies, stars, planets all cosmic debris" "We go forward through time riding the blast wave" "Until we reach another cooling cinder swirling in the afterglow of the Big Bang." "We're back where we started" "Home." "Only now can we really know it." "Smaller, more fragile than we ever imagine" "Destined to die swallowed by a dying sun" "But we shouldn't despair." "We should rejoice" "We've managed to experience the wonders of the universe" "We should celebrate our achievements and enjoy our moment in the sun"
