NASA's Messenger craft has been orbiting Mercury for 88 days. Among its findings: a Saturn-like magnetic field, high concentrations of sulfur, and some support for the notion there is water ice in shadowed craters.
The 13th- and 14th-century Mongol invasion of Asia decreased global carbon dioxide by less than 0.1 part per million, researchers have found.
But tomorrow's could be, unless efforts to combat climate change include much more development of carbon-free sources of energy. The findings appear Thursday in the journal Science.
Trojan asteroid 2008 LC18 is orbiting in a fixed spot in Neptune's orbit where the gravitational pull of Neptune and the sun balance out. Its discovery may help shed light on questions about planetary formation.
Researchers determined that the lunar water likely originated early in the moon's formation history, suggesting that it is, in fact, native to the moon.
Top international scientists will take part in an independent review of the Intergovernmental Panel on Climate Change (IPCC) and its reports on global warming, which have been widely criticized recently for inaccuracies.
A new study estimates that animals and plants will have to migrate, on average, nearly a quarter of a mile each year to keep up with shifting climate belts caused by global warming.
