Ceres' homemade organic materials

Researchers analyzing data from NASA’s Dawn spacecraft have found signs of organic compounds that arose on the surface of Ceres, a dwarf planet one-fourth the diameter of our moon in the asteroid belt between Mars and Jupiter. The compounds’ origins may provide clues about how life on Earth got started.

MESSENGER mission ends with a bang, and more data

After 11 years in space and more than 4,100 laps around Mercury since entering orbit in 2011, NASA’s MESSENGER spacecraft was decommissioned in heroic fashion on April 30, slamming into the planet’s surface at more 14,000 kilometers per hour after it had run out of propellant. Fittingly, it gouged a 16-meter-wide crater of its own amid the myriad others it observed there.

Sun shapes Titan's atmospheric makeup

Saturn’s largest moon, Titan, has a thick atmosphere composed of 98 percent nitrogen and about 1.4 percent methane, as well as small amounts of other gases. In a new study published in the Journal of Geophysical Research: Space Physics, astronomers have identified fluctuations in methane levels in Titan’s thermosphere that appear to be in tune with the 11-year solar cycle.

Red Planet Roundup: March 2015

NASA’s Curiosity rover found evidence that one or more large and long-lasting lakes probably filled Gale Crater in the planet’s warmer and wetter early history. While investigating the lower slopes of Mount Sharp recently at an outcrop called the Murray Formation, the rover photographed thick rock stacks featuring numerous layers of lithified sediment. Such stacks are typical of lake environments, where sediments slowly settle to the bottom and transform into rock over time.
