An Element Critical for (Earth) Life is Spewing out of Enceladus - by spacewriter
The search for water is important in the hunt for life—and habitable conditions—on other worlds. The existence of subsurface oceans in multiple solar system locales indicates that habitable worlds can exist beyond the “Goldilocks zone” where Earth lies, according to Glein.
and other materials. Followup analysis of salt-rich ice grains in the plumes showed the presence of sodium phosphates (a form of salt that combines phosphorus with sodium. Phosphorus is a huge part of life on Earth. DNA and RNA wouldn’t exist without it. The element exists in life-carrying molecules, cell membranes, bones, and teeth. It’s found across a range of life from humans to plankton and without it, life wouldn’t be here.That’s what makes it so amazing to find it on Enceladus.
