NASA announced Enceladus, Saturn's moon, could support life thanks to the presence of hydrogen discovered.
Known as an "ocean-world," Enceladus has been spewing off hydrogen from a plume, said Linda Spilker Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California during the press event.
So far, Enceladus has shown to have the existence of nearly all of the elements of habitability (primarily carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur), except for phosphorus and sulfur. Scientists expect they are present due to Enceladus' rocky core, which is thought to be chemically similar to meteorites, which contain both phosphorus and sulfur.
