Europe Launches Gaia, Its Billion-Star Surveyor
Europe's Gaia spacecraft lifted off from French Guiana Thursday (Dec. 19), carried aloft by a Russian Soyuz-Fregat rocket. Gaia is on its way to a gravitationally stable point about 930,000 miles from Earth, which it should reach in three weeks. Over the next five years, Gaia will precisely map 1 billion Milky Way stars, allowing scientists to create a high-resolution galactic map.

Scientists Plumb Depths of Titan's Hydrocarbon Seas
Saturn's largest moon Titan harbors about 2,000 cubic miles of liquid methane and ethane on its frigid surface, new observations by NASA's Cassini orbiter suggest. The hydrocarbons are contained in an area near Titan's north pole that's just 660,000 square miles in size, a region slightly larger than Alaska.
