Mars sports massive hidden plume of searing rock

A plume of searing hot rock as wide as the continental U.S. is rising up from near the core of Mars and might help explain recent volcanism and earthquakes seen at the Red Planet, scientists say.

Most volcanism on Mars occurred during the first 1.5 billion years of its history, leaving behind giant monuments such as Olympus Mons, the tallest mountain in the solar system. However, scientists had largely thought Mars cooled since then, becoming essentially dead for the past 3 billion years or so. But in recent years, scientists have seen hints of geologic activity after all, and now scientists have found a mushroom-shaped pillar of scorching, buoyant rock below a region called Elysium Planitia that might explain recent findings.
