NYT: there's phosphorus on one of Saturn's moons
Enceladus — the sixth-largest of Saturn’s 146 moons — has a liquid ocean with a rocky floor under its bright, white and frosty surface. Ice volcanoes spew frozen grains of material into space, generating one of the many rings circling the planet.
Now, a team of researchers has discovered that those icy grains contain phosphates. They found them using data from Cassini, a joint NASA-European orbiter that concluded its study of Saturn, its rings and moons in 2017. It is the first time phosphorus has been found in an ocean beyond Earth. The results, which add to the prospect that Enceladus is home to extraterrestrial life, were published on Wednesday in the journal Nature.
“We weren’t expecting this. We didn’t look for it,” said Frank Postberg, a planetary scientist at the Free University of Berlin who led the study. He described the realization that they had found phosphates (chemicals containing the element phosphorus) as a “tantalizing moment.”
Well, when the planet runs out of phosphorus, I guess that we can go to Enceladus?
