Arsia Mons: Is There A Habitable Environment On This Martian Volcano?

The slopes of a giant Martian volcano nearly twice as tall as Mount Everest, called Arsia Mons, were once covered in glacial ice and they may have been home to one of the most recent habitable environments yet found on the Red Planet, according to new research. Arsia Mons is the third tallest volcano on Mars and one of the largest mountains in the solar system. The new analysis of the landforms surrounding Arsia Mons shows that eruptions along the volcano's northwest flank happened at the same time that a glacier covered the region around 210 million years ago. The heat from those eruptions would have melted massive amounts of ice to form englacial lakes — bodies of water that form within glaciers like liquid bubbles in a half-frozen ice cube. read more
