Enceladus — the sixth-largest of Saturn’s 146 moons — has a liquid ocean with a rocky floor under its bright, white and frosty surface.
They found them using data from Cassini, a joint NASA-European orbiter that concluded its study of Saturn, its rings and moons in 2017.
The results, which add to the prospect that Enceladus is home to extraterrestrial life, were published on Wednesday in the journal Nature.
Phosphorus is a key ingredient in human bones and teeth, and scientists say it is the rarest bio-essential ingredient in the cosmos.
Planetary researchers had previously detected the other five key elements on Enceladus: carbon, hydrogen, nitrogen, oxygen and sulfur (the last of which has been tentatively detected).
