Interesting quote:

We previously found that Enceladus’ ocean is rich in a variety of organic compounds ... But now, this new result reveals the clear chemical signature of substantial amounts of phosphorus salts inside icy particles ejected into space by the small moon’s plume. It’s the first time this essential element has been discovered in an ocean beyond Earth.
