"Four hundred million miles from Earth, exists a mini solar system of over 60 moons rotating around a powerful planet of gas." "Its flowing colors and spots hold strange beauty, but contain violent storms and jet streams." "Could this big, bright ball of weather have been the Star of Bethlehem?" "Could one of its moons harbor life beneath its icy crust?" "We expect that branches of life would exist on Europa, just simply because water is the key feature." "I wanna go ice-fishing on Europa." "Cut a hole, put a submersible, look around, see if anything... if anything swims up to the camera and licks the camera." "That's what I wanna do." "And does our own planet owe its survival to this massive comic magnet?" "Jupiter, the giant planet." "The Universe 1x04 Jupiter the giant planet" "Jupiter is half a billion miles from the Sun." "A giant sphere of intrigue." "This turning ball of gas may look like an artist's rendering, but it's the real thing." "Jupiter has the most exotic weather patterns we had ever seen in the solar system." "Jupiter is 84% hydrogen and almost 14% helium, the two lightest and most abundant elements in the Universe, rolled into a mammoth mass." "This thing is eleven times the diameter of Earth, and you could take a thousand Earths and stuffed them inside Jupiter comfortably." "Jupiter really is the lord of the solar system." "You know, about 70% of the mass in all the planets is in Jupiter." "If you talking about planets, Jupiter is the big boy in the block and it really does rule the roost." "Jupiter is the largest planet in the solar system." "Visible to the naked eye." "A day is only 9.9 hours long." "And it takes 11.86 years to orbit the Sun." "A 150 pound person would weight 350 pounds on Jupiter." "There are thunder clouds made of ammonia, sulfur and water." "Exploring Jupiter would be NASA's most daring mission to date." "It's a hostile place, with temperature extremes, from fridging to firing." "Its electromagnetic radiation is intense." "It could kill a traveler to the planet in an instant." "We would need heavy lead protection and that's very difficult to lift off the ground." "So we have some difficult engineering challenges to actually bring human beings to the planet Jupiter." "A landing on Jupiter is... not going to happen." "Jupiter itself is a very gassy planet." "It's made of gas." "So you... would not have a solid surface on which to land and walk around." "You would just keep descending through the clouds and then be eventually crashed by the pressure of Jupiter's atmosphere." "That make a human trip to Jupiter quite a challenge." "But what if we could go there." "Doctor Andrew Ingersoll is an authority on the planet." "He takes us for a ride." "You need a special kind of balloon, because the Jupiter's atmosphere is hydrogen." "Hydrogen is the lightest gas." "A human balloon would sink." "So the only thing that'll flow in a cold hydrogen atmosphere is hot hydrogen." "And so you need a hot-air hydrogen balloon." "For the past ten years, NASA has been developing ultra-long duration balloons, for robotic exploration." "And as we all know, heating hydrogen is a tricky thing." "But just how this behemoth was born, is a puzzle." "The formation of Jupiter is the greatest mystery associated with the planet." "Some believe Jupiter may have been a failed star." "Like the Sun, it had the right ingredients, hydrogen and helium." "But not enough mass to create the internal pressure and temperature necessary to have nuclear fusion." "So, it became a planet instead." "The theory is that there was this cloud in the galaxy that had the same composition of the Sun." "And it collapsed under its own gravity and some stuff was left behind." "And that stuff became the planets." "And the majority of that stuff became Jupiter." "And the rest, of course, went into the Sun." "And there were a couple of little tiny leftovers, like Earth." "Jupiter's spinning gasses attracted light elements, and overtime grew bigger and bigger in the process." "Almost like an oyster, creating layers around the grain of sand to make a pearl." "What gasses and solids Jupiter didn't ingest, it sped out into space." "So Jupiter is like the big brother in the schoolyard, protecting you from bullies that might wreak havoc on your existence." "I tend to think of it as more of the cosmic Frisbee guy." "It's grabbing things out of space and it's also tossing them back out." "It ends up keeping those objects from the inner solar system, where Earth and Mars and Venus are." "By cleaning some of the debris up, kicking some of it out, shooting some of it into the Sun, where it would be lost forever," "Jupiter cleaned out a path that the other planets could exist in some sort of peace." "So dominant is this Frisbee phenomenon," "Earth may owe its very existence to Jupiter." "It influences the courses of comets and even some meteors and asteroids, so that over the NEOs the effect of Jupiter is there, helps takes care what comes near the solar system." "So really the presence of Jupiter may be one reason why we have life on Earth and habitability and be able to have the Earth nice environment instead of getting pummeled by so many comets." "There is no greater proof of Jupiter's power play than what happened during the seven day period in July of 1994." "A comet called Shoemaker-Levy 9 barreled toward Jupiter." "Once under Jupiter's influence there was no going back." "A missile was on a crash course with a ball of gas." "Jupiter's gravitational pull was so great that it broke the comet into small pieces that came in one at a time." "These pieces assaulted the planet at a speed of 37 miles per second." "When you have a missile going at supersonic speeds you get a shock." "You can see sort of clouds of material being jetted up from beneath where it landed." "One of the fire balls generated by the collision with Jupiter's atmosphere flared 1,800 miles in the space." "Had Earth been in the projectile sights the effects of such a smash up would have been catastrophic to say the least." "Similar to the event that wiped out the dinosaurs." "The energies that were released in those fragments hitting was larger than anywhere of ten or twenty times more powerful than the entire world arsenal of bombs." "Take Jupiter out of the picture, bring this giant comet into the inner solar system, where would it have gone?" "We have no idea." "Might have crashed into Earth." "If that comet had crashed into Earth, things would be a lot different around here." "The experts believe that comet strikes on Jupiter may be 8,000 times more frequent that those on Earth thanks to the Frisbee effect." "But it cut both ways because Jupiter has no value system, when it sees an erring comet it may attract it and swallow it up." "But where it flings is anyone's guess and so erring comets can be flung in towards Earth, they can be flung into the Sun, they can be flung out of the solar system." "There's a reason the planet rejects some of the space junk heading its way." "Jupiter being the biggest object in the solar system has the most gravity." "And so other objects literally flees, they have their own trajectory flying by, are bent from where it would be towards Jupiter and usually with an acceleration." "And that acceleration can cause it sometimes to just be ejected completely." "No earthly Frisbee thrower can match Jupiter's flinging force." "It is much faster than any bullet ever known." "It rejects things at a rate of 30 miles per second." "Jupiter's wonders are hard to fathom." "They've captivated men for centuries." "Prehistoric humans realized that it was moving among the stars and it was one of the planets that they appreciated." "Jupiter was the king of the Gods, after all, in Roman mythology." "And there may be a biblical reference to Jupiter." "Ever since I was like five years old I remember people:" ""Oh, that was the star of Bethlehem!"" "And whether or not it really was, obviously we have no way of knowing, but it's not clear whether the star that was talked about is a single star or whether they met an astronomical alignment of objects in the sky, we don't really know." "It's known as conjunction in scientific terms." "According to researches Jupiter and Venus did appear as one large star-like object in August 3 B.C., and would had been visible in eastern night sky." "But it was Galileo, the father of modern astronomy, who made the first recorded sighting of the Jupiter system." "In the early days of 1610, only about 18 months after the telescope was invented, he got his own telescope and he was on Jupiter." "In 1665 Jupiter's most fascinating feature was discovered." "Its giant "red eye" was actually the eye of an enormous storm." "Unlike any experienced on Earth." "This one has raged for at least 300 hundred years." "This weather disturbance is a meteorologist's dream." "Jupiter's Great Red Spot, is truly huge." "You can take Earth and flare it out and then wouldn't even really cover the Spot." "This storm is the hugest storm in the solar system." "And just to give a feeling about it, it's about 12,000 miles." "And the Earth is only 8,000 miles wide." "And the winds blow quiet fast around the edge." "But it's calm in the center." "It's..." "It's not like a hurricane which has an eye and very fast turbulent winds in the center." "Red Spot is rather calm." "If you're in a balloon, it might be a pleasant ride." "As long as you avoided the small scale stuff like the thunderstorms and the turbulent places." "Even though you'd be going very fast it might be quite calm." "Fast as in 350 miles an hour." "The fastest wind ever recorded here on Earth was 175 miles an hour." "But is it an Earth-like storm?" "It's a giant collection of clouds roiling around, lightning going on..." "So we can only model an imagine of what kind of precipitation but condensation in the form of condensed vapor of various gasses." "This famous Red Spot is a high pressure system that can take 10 days to complete a rotation." "Truly a backwards hurricane is called an anticyclone, that's the name for those circles backwards on the direction of a typical hurricane." "That's not the only curious thing." "Hurricanes, as we know them, need water in order to form." "There's no water engine in the Red Spot." "This never-ending weather system is feeding on something else." "But what?" "Jupiter's Great Red Spot is something like a non-stop hurricane." "It's a colossal storm, complete with violent wind and lightning." "Storm chasers would love to go running after it." "Dr. Tim Dowling of the University of Louisville is in the hot for similar phenomena here on Earth." "The Red Spot is..." "Think of it as a huge extreme... lander egg shape of mass, such as an enormous thing that sort of quiets down the fluid and the presses it down into the hotter interior so you don't get thunderstrokes." "But if you go on the edge of the Red Spot, specially north-west, you get some of the most horrific thunderstorms you're gonna find on Jupiter." "The Spot doesn't have an eye and it isn't fueled by water." "There's no ocean over which it forms." "What then keeps it going and going?" "I've always liken it in my own view as..." "like a mini volcano inside of Jupiter." "Actually an atmospheric volcano." "Dr. Baines believes that warmer gasses rise from heat, deep within the planet." "While trying to escape they create a vortex." "So, for some reason I believe there's extra energy right there." "But it's just a theory." "Science is left without answers to that question and others." "Current theories cannot quite explain why the Spot is so well-formed and why it stays in one place." "The plot thickened over the years as scientists learnt even more." "It became a deeper mystery because instead of everything just sort of smooth going around the Red Spot, we saw there's turbulence and there were smaller scale structures that come and go every day, and it was chaotic and triggering and yet the Red Spot just existed and stayed hold on." "Jupiter's storms aren't limited to the Great Red Spot." "Cloud decks three layers thick hover and cover the planet." "If you were inside the atmosphere of Jupiter you would hear very loud thunders." "In fact we have thunders actually which travel four times faster on Jupiter than it does on Earth." "It's about 3,000 miles an hour." "So rain falls twice as fast on Jupiter." "The charge separation that pulls the positive charges to the top of the clouds and the negative charges to the bottom of the clouds is twice as efficient on Jupiter for that reason alone, because the rain is falling so much faster." "Towers of cumulous convection that you see on Jupiter are three times taller." "They go up 30 miles whereas on Earth they go up 6 or 7 miles." "It would be impossible to survive within the Great Red Spot, with its 350 mile-an-hour winds." "By comparison, hurricane Wilma, which had the highest recorded winds of any earthly storm, slammed into the Yucatan peninsula in 2005 with barely a breath," "175 mile-an-hour blasts." "Our weather is simple, Jupiter's is complex." "Now on Jupiter you just basically have one storm system sort of stacked on another stacked on another with lots and lots of rub." "Basically these are the storms in their natural state." "These storms move relentlessly within Jupiter's other distinct feature, streams of fierce jets that continually circle the planet." "Scientists are only beginning to understand what they are and where they come from." "There is a massive eastward flow of material and that means... the material's flowing more than one and a half football fields per second." "That's really moving, you don't want to be in that." "29 other belts and zones of varying width extend outwards from there." "They are what give Jupiter its characteristic appearance." "They move in alternating directions, some eastward, some westward." "They're much smaller scale the high latitude jets than the equatorial one, as far as in comparison to Earth these are massive, super-fast high-speed winds and yet they're just going back and forth." "The planet's rotation rate has something to do with it." "Jupiter generates a lot of energy because it really moves." "So the very nature of the spinning causes" "Jupiter to not just have one jet stream but many jet streams going in opposite directions along the planet." "And so you can see these zones, so what you have is an exaggerated version of Earth's basic weather pattern." "The spectacular swirls are created in surface clouds where the zones meet." "It's believed that the energy ultimately powering this belt phenomenon comes from intense heat deep within." "It's not unlike something we see every day." "Buy a boiler pot of water on a stove, it'll start bubbling and bubbles come out from the bottom and try to get out trying to circulate that water that currents around, so... same thing inside Jupiter, we have gases and liquids down there" "that are trying to get the heat out." "There are basic questions, basic pieces of physics to go after to explain the massive jets." "Shouldn't we be able to explain that?" "Earth has just one primary jet stream, it moves eastward, and another major flow that blows westward, the trade winds." "Triple that power and you've got the jet streams of Jupiter." "Totally different from Earth." "And yet..." "I should be careful, not totally different from Earth, just Earth on steroids." "And you ask yourself, wow!" "If I understood what's going on on Jupiter," "Earth would be just a piece of cake." "Jupiter's mysteries aren't limited to the planet itself." "Some of its most intriguing elements are circling around it." "Jupiter's got several dozen moons that are big enough to be seen and has probably got a lot more that are too small to be seen with current technology and no doubt in coming years more will be discovered." "Some of the moons almost have the size of some planets." "So really Jupiter has its own little solar system." "Thanks to its incredible gravitational pull, it sucked in asteroids along with other space debris." "For the most part there is order." "But there are some erratic moons in orbit around Jupiter." "It's managed chaos." "Can you imagine a bunch of runners in the track, in their lanes, each runner stays and they won't collide." "It's kind of a celestial mechanics." "Each moon holds its own fascination." "Four of Jupiter's prominent moons were discovered by Galileo." "He first observed that they revolved around the planet." "They are named for Jupiter, the god's lovers." "The first major moon you come into is Io, which is this very active place." "There are lots of volcanoes." "It's almost all the time going off." "Shooting out magma 200 miles into space," "Io is a wonder pop-mark with over a hundred volcanoes, some the size of California which seem to turn themselves on and off." "Ganymede is the largest moon in our solar system." "Five times the size of Earth's Moon." "Callisto is the most heavily cratered." "It has clearly taken a beating in its lifetime." "Then there is Europa, the ice queen to Jupiter's king." "No one knows its make-up for sure." "It looks like a cracked egg." "It really looks like the whole thing had looped water on it sometime it froze and it cracked." "And we believe that these patterns are due to tidal forces that crack it." "As alien as Europa seems it is smooth and glassy in some spots, hilly in others." "In fact it is remarkably similar to one of Earth's frozen wonderlands." "There is a lake in Antarctica called lake Vostok that scientists think is an analogy to what we see on Europa." "Antarctica has a huge thick ice crust and underneath there is this liquid lake." "And we think this may be very similar to the water ice underneath the surface that we see on Europa." "If you go down through the crust you got to the ice and then if you get liquid water." "And we are very convinced that there's liquid water down there." "It's the only place that we know, beside the Earth which has liquid water and large bodies that have been there, we believe for more than a million or two million years." "And where there's water, could there be life?" "Jupiter's moon Europa is bursting with secrets." "It may even have warm thermal vents deep below its frozen crust." "In fact there's an immense ocean that's bigger than the Pacific Ocean worth half liquid water down there." "That is sitting there for things to happen to." "The presence of water means one thing." "We may not be alone." "I wanna go ice-fishing on Europa." "Cut a hole, put a submersible, look around, see if anything... anything swims up to the camera and licks the camera." "That's what I wanna do." "One scientist is planning just such a fishing trip." "At this outdoor lab, near Austin, Texas, hopes are hanging on a little robot." "This is designed for exploration in unknown territory, completely unknown territory, and search for biological live." "It's a deep Phreatic thermal explorer, or "DepthX" for short." "Its proving ground right now is a local quarry." "And there are big plans for its future." "If everything went according the plan we would launch around 2017." "It would be at Europa by 2018... and by 2019 for certain we'll know whether there's life off Earth." "That's the game." "DepthX is the brainchild of engineer Bill Stone." "He and a team of scientists have staked their reputations on it." "They spent 6 years developing the concept and building the prototype." "It's part of an ambitious project that would see it carried into space, sent through 6 miles of ice and into Europa's ocean." "To divide it down into all the various vehicle, you have a a parent vehicle which takes you to orbit around the moon Europa." "There would be a lander... that would land on the ice, then there's a second stage of the lander which melts its way from 3 to 5 kilometers of ice cap and then at that point you kick out the 3rd stage." "We need a fast moving device, that would be sort of torpedo-shaped, most likely nuclear propelled." "And that would drive for thousands of kilometers around the central ocean of Europa." "Is that really feasible?" "NASA thinks so." "The space agency is onboard with the money and its blessing, an investment in the search for life." "If life exists on Jupiter's moon Europa, could it walk, talk or fly?" "It would be little viruses or no, maybe a best bacteria?" "We would expect only to see primitive life forms." "But they might be some more else that we see on Earth, we just don't know." "Scientists are encouraged by the discovering of strange and hardy lifeforms found in the most inhospitable places on Earth." "Two worms, for example, survive and thrive in total darkness." "Extreme pressure isn't a problem." "The creatures were discovered in 1977 several miles below the surface of the Galapagos rift." "They exist in water, near superheated thermal vents." "It's believed that these very conditions, darkness, high pressure and hydrothermal vents, are present on Europa." "If you could have hydrothermal vents kicking out warmth and nutrients down and near the core of Europa, and organisms would have fed off of that material just likely might have in the early Earth." "And while two worms might not be lurking beneath Europa's icy shell, something else could be." "This microbial life is the bulk of life on Earth." "We expect that branches of that type of life would exists on Europa, just simply because water is the key feature." "Finding it consumes scientist Bill Stone." "Its DepthX may answer a question that excites secrets of knowledge." "And we have the robot behavior look for signs of life and then try to collect the samples based of what it's sensing." "Stone's baby is in its infancy." "At the same time it is futuristic and advanced." "It's a high tech toy like no other, that might show our world what another is all about." "Our first contact with extraterrestrial life may be on Jupiter's moon, Europa." "The DepthX robot, or more accurately "Hydrobot", is being designed to ultimately think, move and explore without help from man." "And that is all to be done by the robot itself." "We're not gonna be guiding it to do that." "That's gonna be a big step forward in what we would call robot science autonomy." "It's a real life hell." "The start of a new "Space Odyssey"." "We're literally at the bottom edge let the type look surface and we won't see it again until it tell us what's down there." "DepthX would be able to extract and analyze samples on its own as it navigates the ocean." "This outer tube we see down here is where we pull in water samples and store them in one later bag, we have five of them on-board." "But before it does that it actually powers through a series of micro pumps here on the left and brings it into and on-board microscope." "And that microscope will take images of what's in the water down to about five microns." "So we can see most of the typical types of microbial life, from five to two hundred microns, on screen." "The robot will use that to discriminate to determine if there is life and then grab a sample." "DepthX and its systems must be made smaller to work in space and it still must pass trials under ice floes." "We are testing this in Antarctica to make sure all works totally under ice." "The question of life on Europa is probably the big meal***unknown, because that would change our view of the Universe, basically." "I mean, if this little moon sitting out there in his hostile environment of Jupiter can have life form on it, that means that probably tell us that, that life is almost everywhere." "The sign is there, I mean, I think searching for like is one of the most compelling things that we can do as... as not only as scientist but as a race... as human beings." "It's a giant lead, and not just for mankind." "Nor for robot kind." "Of all Jupiter's imposing features, none is more impressive than the one you cannot see." "It's bigger by far than the Great Red Spot, more dynamic than the bands of jet streams, and as lethal as any killer known to men." "You have one of the most powerful radiation environment in the solar system, beside from the Sun." "The magnetic field of Jupiter is the largest entity, I believe, in the solar system." "It is a bubble, 450 million miles long buzzing with electrically charged particles." "It's Jupiter's magnetosphere." "The Sun's sitting here putting out the solar wind, and the solar wind is charged particle of protons and electrons." "These particles flow along at 1 million miles an hour." "And Jupiter basically capture these sort of protons and electrons." "All these charged particles are electrical current and is has it then in the space circling around Jupiter" "No word in the english language accurately conveys the enormity of this phenomenon." "The magnetosphere of Jupiter is the biggest object is the solar system." "Is a lot bigger than the Sun." "Comparisons are the best measure of this mega-mighty-wonder." "If it were visible in the night sky, it would be many, many times bigger than the moon." "It's enormous." "Even though it's five times as far away from Earth as the Sun is, it still would look immense in the night sky." "If visible it would take a familiar form: a windsock." "There's a rounded section facing away from the planet, in one direction, with a tail flowing out the other." "This windsock reaches the outer orbit of Saturn." "Power plant Jupiter generates up to ten million amps of electrical current." "The biggest planet in the solar system can conduct electricity all the way through and around it." "This conductivity creates a phenomenon we can see, when the excited charged particles escape." "Jupiter has auroras, because when those particles leak in and crash into the upper atmosphere, it glows." "Just as Earth has auroras." "These ghostly auroras are a thousand times more powerful than Earth's northern and southern lights." "They measure up to 1,200 miles across." "If you could stand under them, they'd fill the entire sky, moving at lightning speed, ten thousand miles an hour." "Jupiter's magnetic field is a monster and it roars." "In fact it's speaking to us, right now." "Jupiter..." "The giant of the solar system has something to say, if you're listening." "We can hear what we call "lion roars", 'cause it has this roaring sound." "We can hear whistler modes, we can hear hiss..." "And whistles that are going:" "And these are all indications of dynamics things that are happening in the magnetosphere now." "If you find yourself driving on a dark desert highway, your AM radio might just tune in to the strange sounds of Jupiter's magnetosphere." "The bursts are as short as a few seconds, and as long as a couple of minutes." "They come and go every hour too." "Most of it sounds like static, but every once in a while you pick up something that sounds like a rising tone or a falling tone." "Sound listeners have described audio spasms that sound like woodpeckers or waves crashing on the beach." "The noise is disturbing." "But just why the planet was talking, remained a mystery until Voyager II passed through the outer magnetosphere, in 1979." "Nobody really understood for a long time how those signals were generated." "So that was one of those things that was on my mind when I got interested in Jupiter." "What in the world was going on with these radio emissions?" "It is one of the few secrets finally surrendered by Jupiter." "And that answered some questions but it raised new ones." "And..." "I think that's the way it should be." "If you don't have questions, it gets kind of boring endures." "So..." "I think that the fact that the planets don't give up their secrets easily, or the Universe doesn't, that's part of the game, it's what it makes it interesting." "Jupiter keeps astounding and confounding scientists." "One surprise came in 1979, when it was discovered that Jupiter has a ring." "It's nothing on the order of Saturn's, still, it's another feature that fascinates." "All of the giant planets have rings, probably leftover from when the planets formed, and the moons coagulated out of the gas that was there and then it could be a failed moon." "So, Jupiter's ring comes from material being knocked off of one of the interior moons." "So its dust is collected from material that's coming in from outside moons." "The ring is slowly growing as new material flows into it." "And there's a whole other side of the planet that remains a mystery." "Why do the storm spots keep forming." "There's the Dark Spot, for example." "Glimpses of it were first spied in 1997." "It appeared to be a huge ominous cloud twice the size of Earth, hovering above Jupiter's North Pole." "There's a host of other spots too." "There are other sort of smaller cousins that have come and gone, there were three ovals about half a third of the size of the Red Spot." "And they used to occupy the same latitude end in the southern atmosphere." "And they've been around since the 1930's." "And... amateur astronomers saw them formed and they were around till the late 90's and they... two of them merged with each other, and then the remaining two merged, and now there's one." "And it keeps transforming." "They have turned to red about six months ago, and it's now call it the Little Red Spot, because it turned color and why did they turn color is a big question." "So there's chemistry going on, or some type of vector dynamics is going out it just kicked in and we need to start studying that." "Jupiter is a hostile and restless planet." "Its giant gaseous body and violent storms, make it one of the most alien environments in the solar system." "Even though it is half a billion miles from us, we may have more in common with our cousin planet than we think." "I think the lesson to learn from Jupiter here is..." "Whatever's going on in our climate and our weather patterns here on Earth," "Jupiter has more of it, but Earth is not an island, and they're better examples of what 's going on on Earth than even Earth itself." "For scientists, Jupiter is the king of many questions concerning our solar system, and could possibly hold the answers."
