Mercury's 400 C Heat May Help It make Its Own Ice

Mercury's North Pole Ice Deposits

It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun likely helps make some of that ice.

Mercury's Interior

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it -- very, very carefully.

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.
