After spending most of an hour describing the evolution of life on Earth, it was time to turn toward alien terrains and chemistries—to a place that, while not so very far away, could host some very, very strange lifeforms. Ask an astrobiologist about the prospect of finding life on Titan, and they’ll say the shrouded, orange moon is the place to go if you’re looking for bizarre life. In the 1990s, the Hubble space telescope offered hints of a wet world, but it wouldn’t be until NASA’s Cassini mission that scientists got a good look at the moon.
Powering metabolism is tricky at those temperatures, though, which is one of the reasons why some scientists are hesitant to focus on sending a probe to Titan.
Second, the scene with Tyson in the spacecraft shows a craggy, chaotic seafloor, with things that look like hydrothermal vents. Turns out, we know quite a lot about Titan’s seashores, and slightly less about its seafloors.
Getting the depth profile meant that scientists could estimate how much liquid hydrocarbon rests in Ligeia Mare: As much as 100 times more than the oil and gas reserves on Earth combined.
What happens if there is a spark, such as a retro-rocket; will the entire place go up in flames ( or explode)? Hey can liquid water can be present below Titan’s frozen crust due to effect of gravity of Saturn which heats up the core due to contraction an relaxation as Titan revolve around the Saturn in eliptical orbit.

Get a first look at the stunning new science series hosted by astrophysicist Neil deGrasse Tyson. When checked, Shutterstock's safe search screens restricted content and excludes it from your search results. As with the legendary original series, the new Cosmos is the saga of how we discovered the laws of nature and found our coordinates in space and time.


The series invents new modes of scientific storytelling to reveal the grandeur of the universe and re-invent celebrated elements of the original series, including the Cosmic Calendar and the Ship of the Imagination.

If it does, it promises to be unlike anything we’ve ever seen before,” Tyson says, in the episode.
Methane and ethane, compounds that are gassy on Earth, are liquid on Titan’s frigid surface. Lunine has spent years studying Titan; at one point, he and his colleagues designed a spacecraft that could land on the moon and float in one of its hydrocarbon seas [pdf].
In the 1970s, Carl Sagan and chemist Bishun Khare, then at Cornell University, were already publishing papers describing the organic chemistry that might be taking place on the Saturnian moon. In 2004, the spacecraft began peering beneath Titan’s cloudy shroud; in 2005, Cassini sent the Huygens probe parachuting through the haze to a spot on Titan’s equator. Nonetheless, astrobiologists are studying the reactions and pathways that life might use to gain some traction on Titan—including things like breathing hydrogen and eating acetylene.
First, if I were a weird life form on Titan, would I be able to see Saturn through Titan’s hundreds of kilometers of haze?
Until now, scientists had mostly used seashore shapes and surrounding topography to infer what the seafloors might be like. Peering into the depth of Kraken Mare, which covers an area of at least 400,000 square kilometers, or approximately equal to the size of Germany.
The moon has plenty of water, and while it is solid at the surface, it may be liquid in the interior. Scientists do think Titan has a subsurface water ocean that could *possibly* sustain life, but gets pretty complicated. This is her space to talk about space -- from other worlds to exploding stars to the fabric of the universe. Phenomena is hosted by National Geographic magazine, which invites you to join the conversation. The series brings to life never-before-told stories of the heroic quest for knowledge, transporting viewers to new worlds and across the universe for a vision of the cosmos on the grandest, and the smallest, scale. The most profound scientific concepts are presented with stunning clarity, uniting skepticism and wonder, and weaving rigorous science with the emotional and spiritual into a transcendent experience. Toward the end of the episode, Neil DeGrasse Tyson eases his spaceship into one of the moon’s dark, oily seas. Life that, instead of being water-based, uses those slick, liquid hydrocarbons as a solvent.


At that point, though, the large bodies of liquid on the moon’s surface hadn’t yet been spotted, so Sagan and Khare were thinking about the types of reactions that might be taking place in the moon’s atmosphere (in 1982, Sagan and Stanley Dermott proposed that such lakes might exist).
Data sent back to Earth revealed a world that looks very much like ours—just with a completely different chemistry. Or would the most spectacular planetscape in the solar system be hidden behind that smoggy curtain?
But in May 2013, the Cassini spacecraft aimed its radar at the depths of Ligeia Mare, the second largest sea on Titan (Kraken Mare, which Tyson took a swim in, is the largest). Our best fit model that also works chemically is to have a warm dehydrating silicate core underlying the subsurface water ocean, with a very thin or possibly broken high pressure ice layer in between. ???????????? ?? ??????????? ?? ?? ?????? ??????????, ??? ???????? ?? ??? ??????? ???????????? ?????? ??????????? ??? ?? ?????????? ?? ?? ?????????????? ????????, ?? ?????????? ????????? ?? ??????? ??? ???????????? ???????? – ??? ??? ?????? ??? ??????.
The regional premier comes just three days after its National Geographic Channel launch, which was the channel’s largest global launch ever for a television series. He wanted to see what was down there—more specifically, what kind of life might be down there.
It’s so cold that water ice is rock-hard—in fact, the rocks littering the moon’s surface are made from water. Life that, if we find it, would demonstrate a second genesis—a second origin—and be suggestive of the ease with which life can populate the cosmos. Later, Sagan and Khare would show it was possible to make amino acids using the elements found in the moon’s haze. Using the radar data, the team created a map of the sea’s floor—its bathymetry—and saw that Ligeia Mare plunges to a depth of 160 meters (524 feet). ??? «COSMOS: A SPACETIME ODYSSEY» ?? ???????????? ????? ??????? ????????????? ???????? ??? ?? ??? ?????? ?? ???????????? ?? ???????? ??? ????????? ???? ??? ??? ?????????? ??? ??????????? ????????! In fact, Titan is the only place in the solar system, besides Earth, with stable liquids on its surface. Water is everywhere on Titan, but it’s locked in a state that’s inaccessible for life-sustaining chemistries. The northern seabed is gentler and smoother than the southern, which is riven with flooded valleys and punctuated by steep peaks. The old story that the ocean is perched between two layers of thick ice really doesn’t seem to explain all the data very well. Those liquids flow through rivers and streams, pool into lakes and seas, sculpt shorelines and surround islands, just like on Earth.
