NASA's Gravity Recovery And Interior Laboratory (GRAIL)-B spacecraft successfully executed its first flight path correction maneuver Wednesday, Oct. 5.

Space Observatory Provides Clues to Creation of Earth's Oceans
Oct. 6, 2011
Astronomers have found a new cosmic source for the same kind of water that appeared on Earth billions of years ago and created the oceans. The findings may help explain how Earth's surface ended up covered in water.

An Unusual Multi-Planet System
Oct. 5, 2011
Astronomers have discovered a multi-planet system containing a super-Earth and two Neptune-sized planets. Uniquely, the planets orbit in resonance with each other and around a star similar to the Sun.

The Massive Mountains of Vesta

Mars Atmosphere is Supersaturated with Water
Oct. 3, 2011
A new analysis of data from ESA's Mars Express spacecraft has revealed that the atmosphere of Mars is supersaturated with water vapor. The findings could help astrobiologists determine if Mars once supported habitable environments for life.

Dawn Spacecraft Begins New Vesta Mapping Orbit
Oct. 3, 2011
NASA's Dawn spacecraft has completed a gentle spiral into its new science orbit for an even closer view of the giant asteroid Vesta. Dawn began sending science data on Sept. 29 from this new orbit, known as the high altitude mapping orbit (HAMO).

Heavy Metal Stars Produce Earth-Like Planets
Sept. 29, 2011
Examining the wealth of data from Kepler, astronomers have seen a positive correlation between stellar composition and planetary formation, a correlation that could affect how we search for life in the universe.

Doubts Over Fomalhaut b
Sept. 28, 2011
Formalhaut b has been billed as the first exoplanet to be directly imaged in optical wavelengths. Now, it's identity is being questioned. Determining the effectiveness of planet-hunting techniques is important for astrobiologists who are searching for habitable worlds around distant stars.
