The subsurface ocean on an icy moon of Saturn appears to have the ingredients needed for “habitability.'
published Wednesday in the journal Nature, makes Enceladus all the more intriguing in the search for habitable worlds beyond Earth.is based on data from an instrument on board NASA’s Cassini spacecraft, which explored Saturn and its moons for 13 years before engineers sent it plunging into the gas giant’s atmosphere in 2017.
The plumes have sometimes been called “geysers,” but Postberg doesn’t like the term, as it suggests Old Faithful-like eruptions of liquid water. Phosphorus is the “P” in CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur — the sextet of elements that, along with water and energy, are foundational to biochemistry on
