NASA announced today that it has discovered large concentrations of water ice in impact craters at Mercury’s north and south poles.
Areas in red may contain ice. (Why would you pick red, NASA? Maybe not so clever after all.) NASA also explained the unexplainable:
Given its proximity to the sun, Mercury would seem to be an unlikely place to find ice. However, the tilt of Mercury’s rotational axis is less than 1 degree, and as a result, there are pockets at the planet’s poles that never see sunlight.
In other NASA news, THIS.
