The last place you would except water, much less ice, to exist is on the surface of Mercury. But as NASA announced last week, there’s abundant evidence that water ice exists on the planet nearest to the sun, based on data from the Messenger spacecraft, which is orbiting the planet.
The ice can remain frozen because there are portions of the planet that never see the light of day, particularly some areas deep within craters, as seen in the NASA video above.
“Parts of Prokofiev crater (center) and Kandinsky crater (upper left side of Prokofiev) stay in darkness, making it possible for ice to persist on the surface,” according to the NASA website.
Below are some photos taken of Mercury by Messenger.
