Life on a Saturn moon? Study finds key ingredient for biological building blocks

The Cassini spacecraft saw that one of Saturn’s moons, Enceladus, shoots out jets from its south pole. Scientists used the Ion and Neutral Mass Spectrometer (INMS) on Cassini to study the compounds in these jets. They found water (H2O), carbon dioxide (CO2), methane (CH4), ammonia (NH3), and hydrogen (H2) in the material that’s ejected. Figuring out the more minor ingredients in the jets…
