“Trail from Hydrogen Could Lead to Life” –Saturn’s Enceladus (LISTEN –NPR Science)



New NASA research from the Cassini mission has found new excitement on one of Saturn’s moons: plumes of vapor emerging from Enceladus contain large amounts of molecular hydrogen. More importantly, this hydrogen seems to be the product of hydrothermal activity in the moon’s ocean…and is a strong hint that the moon has conditions favorable to microbial life.

Scott Bolton, a co-investigator for the Cassini mission and co-author on the research, explains why the trail from hydrogen could lead to life, and his hopes for future missions to ocean worlds like Enceladus and Jupiter’s Europa.
