    As the Greenland Ice Sheet Retreats, Mercury is Being Released From the Bedrock Below

    Scientists have found that Greenland’s bedrock is rich with mercury in some areas — and as the ice sheet rapidly melts, that mercury is being released into local waters.

    MESSENGER Data Reveal Evidence of Ancient Carbon-Rich Crust on Mercury

    Mercury’s dark surface is revealing intriguing new clues about the formation of the solar system, including evidence announced today that the planet closest to the Sun may have formed in part from carbon, a key component of life.

    Soon-to-End Mercury Mission May Hold Clues to Earth’s Evolution

    NASA’s MESSENGER spacecraft has been orbiting Mercury for the last four years, giving scientists an unprecedented look at our solar system’s innermost planet. But now the craft’s fuel supply is exhausted; inexorably drawn in by Mercury’s gravity, it is scheduled to crash in April. Sean Solomon, director of Columbia University’s Lamont-Doherty Earth Observatory, has been…

    Frozen Water on Mercury, NASA Confirms

    Mercury, the planet closest to the Sun, may hold at least 100 billion tons of ice in permanently shaded craters near its north pole, NASA scientists announced Thursday. The findings come as NASA’s MESSENGER spacecraft nears its second year of orbit around Mercury. MESSENGER’s lead investigator, Sean Solomon, is director of Columbia University’s Lamont-Doherty Earth…
