ThunderBird89 writes "NASA hus just released the latest results of the MESSENGER flyby, which indicate that Mercury is just more than the dead rock it was thought to be. Findings indicate a dipolar magnetic field powered by core cooling, massive amounts of water in the exosphere, and a tail of sodium ions 25,000 miles long.
Check out the full mission report here, and the report about water here"
