The search for habitable planets has always run into one big problem: no water on these space bound spheres. Water is a vital source of life, finding it on another planet is always a big boon in the ideas of trying to get out there to colonize another world.
Well, now NASA can add a new planet—albeit a dwarf one—to the list of planets with a form of water on the surface: Ceres. First discovered in 1772 by Johann Elert Bode, Ceres is the largest object in the asteroid belt that sits between Mars and Jupiter. It has a rocky core and now is confirmed to have water ice in one of its many shadowy regions that never see the light of day. These regions are about 350 degrees below zero!
Water ice is common on the dwarf planet, much more than previously thought—there could even be ice volcanoes that spout ice mixed with mud and salt. All of this makes it clear that at some point Ceres had liquid water.
What does this mean for us? Not much now, but as time goes on and space travel gets increasingly more common for us as humans we could find ourselves ready to look into a little planet that has the possibility for liquid water.
