It’s the only body, apart from the Earth, that we know of which has a liquid phase at the surface which will rain out of the sky and form rivers, and pool together in seas and lakes - it’s a marvellous place. Otherwise, what have we been wasting our time doing? How warm could it get before losing its methane lakes and its atmosphere? It’s just on the cusp of being liquid on Titan. Titan is already warm enough for life if you go inside of it to where we’re pretty sure there’s an internal ocean of liquid water because we know the surface is de-coupled from its core and they rotate at slightly different rates. I've heard that Saturn's moon Titan has many of the prerequisite building blocks for life. There IS oxygen on the planet in the form of ice as well as liquid water under the surface – so we could, in theory, generate breathable air. If we’re still around in 5 billion years time, we’ll have ways to travel from one star to another I would hope. To answer the question about what will happen when the Sun warms up towards a red giant, which won’t happen for about 5 billion years so no need to worry. I think if the surface temperature rises by about 5 degrees, that methane will all be lost. TFL and SWtrains causing an environmental hazard, Forest floor threatened by nitrogen pollution, Coronavirus: sex differences in the spotlight. Although all living things on Earth (including methanogens) use liquid water as a solvent, it is conceivable that life on Titan might instead use a liquid hydrocarbon, such as methane or ethane. What are the best links for up to date COVID-19 statistics? My question is this: When our sun becomes a red giant will this warm up Titan and, if so, what will happen to it? So, inside Titan, you could have Earth-like life or the kind of life we get at hot vents around the Earth’s ocean floor even at the present day. Yes, Titan will probably warm up and probably not be swallowed by the Sun so it will still be there. Yet its extreme cold allows methane to exist in liquid form instead of water and helps Titan retain its unique, dense atmosphere. ©The Naked Scientists® 2000–2020 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. To answer the question about what will happen when the Sun warms up towards a red giant, which won’t happen for about 5 billion years so no need to worry. I don’t think we’ll be looking to cling on by evolving into something which can live on Titan. Can We Live On Titan- whatifhub.com The bad news is that Titan doesn’t have any breathable oxygen, which… well… it really isn’t great.. but it seems that things can change. Information presented on this website is the opinion of the individual contributors and does not reflect the general views of the administrators, editors, moderators, sponsors, Cambridge University or the public at large. Water is a stronger solvent than hydrocarbons; however, water is more chemically reactive, and can break down large organic molecules through hydrolysis. Should you get a vaccine if you already had COVID? So, inside Titan, you could have Earth-like life or the kind of life we get at hot vents around the Earth’s ocean floor even at the present day. We’d have to live on the rocky remains of what’s inside which may be buried in too much water. It rather depends on how much of that water is then lost. A life-form whose solvent was a hydrocarbon would not face the risk of its biomolecules being destroyed in this way. Could it become warm enough for life to develop? Make a donation to support the Naked Scientists. It doesn’t need much warming before Titan will lose its methane lakes. How Humans Could Live on Saturn's Moon Titan (Infographic) Titan is probably the least inhospitable place in the outer solar system, but remember to bring oxygen and warm clothing… David Rothery from the Open University explained how we're unlikely to find a home from home on Titan... David - There are many parts to Renee’s question. So, it will have lost its methane. Well before the Sun has swelled up to a red giant and burnt the Earth away, Titan will have lost its liquid methane at the surface and most of the methane then will also be lost from the atmosphere, I expect, because it will be broken down by ultraviolet light into hydrogen which will escape, and carbon which will react with something or other.
