The waters of Enceladus are a tantalizing place in the search for life. Phosphorus, a key ingredient for life on Earth, has been found in the subsurface oceans of Saturn’s icy moon — the first time phosphorus has been found in an ocean beyond Earth. Chris Glein, a lead scientist involved with the detection, joined this week’s Planetary Radio to talk about the discovery and its implications for the search for life.
