The search for extraterrestrial life in the water worlds close to home

Liquid water is considered a necessary attribute of a habitable planet. The recent discovery of seven exoplanets believed to be carrying water around a star 40 light years from our Sun has hence raised the possibility that they could harbour life.

But there's evidence to suggest that we might not even need to venture outside of our own solar system to find extraterrestrial life. Two moons that orbit Jupiter and Saturn - Europa and Enceladus respectively - are both covered by icy oceans. Ongoing research into the adaptability of arctic microorganisms on Earth has found that there is a possibility they could survive on Europa and Enceladus. Life on these moons may be possible, but how likely is it?


Matt was joined by Andrew McMinn, Professor of Antarctic Science at the University of Tasmania, to discuss the likelihood of life elsewhere.
