»» The Surface of Mars is an Unlikely Place for Life After a 600 Million Year Drought
[Friday, February 3, 2012] Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface

»» First plants caused ice ages
[Thursday, February 2, 2012] New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published today (1 February 2012) in Nature Geoscience.

»» New Super-Earth Detected WIthin The Habitable Zone of a Nearby Star
[Thursday, February 2, 2012] An international team of scientists has discovered a potentially habitable super-Earth orbiting a nearby star. With an orbital period of about 28 days and a minimum mass 4.5 times that of the Earth, the planet orbits within the star's "habitable zone".

»» NASA's Kepler Announces 11 Planetary Systems Hosting 26 Planets
[Thursday, January 26, 2012] These discoveries nearly double the number of verified planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form.

»» Direct Imaging of Extra-solar Planets - Homogeneous Comparison of Detected Planets and Candidates
[Thursday, January 19, 2012] Searching the literature, we found 25 stars with directly imaged planets and candidates. We gathered photometric and spectral information for all these objects to derive their luminosities in a homogeneous way.

»» Biologists Replicate Key Evolutionary Step in Life on Earth
[Tuesday, January 17, 2012] More than 500 million years ago, single-celled organisms on Earth's surface began forming multi-cellular clusters that ultimately became plants and animals. Just how that happened is a question that has eluded evolutionary biologists.

»» Habitability of Earth-type Planets and Moons in the Kepler-16 System
[Monday, January 16, 2012] We demonstrate that habitable Earth-type planets and moons can exist in the Kepler-16 system by investigating their orbital stability in the standard and extended habitable zone (HZ).
