The icy moons of Jupiter and Saturn are home to vast oceans, making them some of the most promising candidates for finding potentially habitable places for life in our Solar System. Dr. Kevin Hand, astrobiologist and deputy chief scientist for solar system exploration at NASA JPL, guides us through these ocean worlds and shows us how Earth’s oceans may hold the key to finding life on other worlds.

The Search for Life in Oceans Beyond Earth was part of Space Science Week 2017, and was originally broadcasted March 29. The webcast is available through the National Academy of Sciences Livestream channel, NAS-Webcast.
