Mercury's Poles May Be Icier Than Previously Thought

The scorching hot surface of Mercury seems like an unlikely place to find ice, but research over the past three decades has suggested that water is frozen on the first rock from the Sun, hidden away on crater floors that are permanently shadowed from the Sun's blistering rays.

Mercury is Tectonically Active

It's small, it's hot, and it's shrinking. New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet.
