Water Eruptions on Europa Mean that Conditions Are Ripe for Life

Jupiter's moon Europa is covered in a thick layer of ice, but it has a turbulent ocean that lies beneath. Today astronomers announced that new observations show this water is erupting in massive plumes like water volcanoes. It's a discovery that could have serious implications for Europa's potential to harbor life. » 12/12/13 8:00am 12/12/13 8:00am

It may be easier to find alien life on Europa than we thought

Jupiter's moon Europa is one of the more intriguing candidates for extraterrestrial life in our solar system. New models suggest that its ice-covered waters are turbulent near the lower latitudes, giving rise to its chaotic equatorial landscapes. Intriguingly, these warm waters may make it easier for life to make it… » 12/03/13 9:55am 12/03/13 9:55am
