Their conclusion: life could exist, but it wouldn't look anything like we expect here on Earth. But scientists are still currently puzzled by the amount of methane that persists in Titan's atmosphere. Titan's atmosphere is mostly nitrogen but there are also methane and many other organic compounds. Could there be oceans of methane on or under the surface? Methane is a by-product of the metabolism of many organisms. Such organisms would inhale hydrogen in place of oxygen, metabolize it with acetylene instead of glucose, and exhale methane instead of carbon dioxide. Organic compounds form when sunlight destroys methane. While humans (and all other forms of Earth life) would have a hard time coping in this chilly, waterless environment, researchers believe that life could still be possible on Titan. Cassini had revealed something..

According to one exotic theory, long ago, the impact of a meteorite, for example, might have provided enough heat to liquify water for perhaps a few hundred or thousand years. Titan, Saturn's largest moon, is a mysterious place. Could this mean there is life on Titan? It says that life may exist in liquid methane bodies on Titan in the same way as life exists on Earth in water bodies. Titan is not a pleasant place for life. Is life on Titan possible? Titan's surface is -180°C. It has lakes of liquid methane, and even weather. Titan is not a pleasant place for life. On Earth today, it is life itself that refreshes the methane supply. Given the differences, scientists ponder the best places to look for Titan life. The liquid that fills Titan's lakes and rivers is not water, but liquid methane, probably mixed with other substances like liquid ethane, all of which are gases here on Earth. Studying its potential for life could help us learn about the beginnings of life here as well. If sunlight is continuously destroying methane, how is methane getting into the atmosphere? According to one exotic theory, long ago, the impact of a meteorite, for example, might have provided enough heat to … Titan, the cloudy moon of Saturn, is one of the least hostile places (for humans) in the outer solar system. It is far too cold for liquid water to exist, and all known forms of life need liquid water. On Earth, the simplest biological sources, such as those associated with peat bogs, rice fields and ruminant animals, continuously supply fresh gas to replace that destroyed by oxidation. Its thick atmosphere is rich in organic compounds. How do they form on Titan?

Will they help us to discover how life began on Earth? Life — in the sense of things which metabolise, grow, and reproduce — could well exist on the surface of Titan, but would need to be based on chemistry different to Earth life. You have already liked this page, you can only like it once. Some of them would be signs of life if they were on our planet. It is far too cold for liquid water to exist, and all known forms of life need liquid water. You couldn’t take Earth organisms to the surface of Titan and expect them to live. However, it is unlikely that Titan is a site for life today. Titan's surface is -180°C. One of the most fascinating hypotheses for Titan's habitability came in 2015, when chemical engineers in the US created a template explaining how life on Titan – and other places in the Universe – could be methane-based and oxygen-free.
