One of the most surprising discoveries in recent years in the outer Solar System is that there are small moons which have oceans inside them. Jupiter’s moon Europa and Saturn’s moon Enceladus are now known to have global […]

The 'Floating Hills' of Pluto: Icebergs In a Frozen Nitrogen Sea

Icebergs on Pluto: the large blocks of water ice float in a "sea" of nitrogen ice and are thought to have broken off from the rugged and mountainous highlands. Image Credit: NASA/JHUAPL/SwRI
