- Jul 24, 2013Scientists have found that purple bacteria from Earth can also survive in the presence of extreme 'alien' light simulated in the laboratory. The key to survival lies in how the light arrives at the organism.
- Jul 23, 2013NASA's MAVEN mission is set to launch later this year and will carry an instrument to measure charged gas particles in Mars' upper atmosphere. The data will help astrobiologists understand if Mars' atmosphere was once substantial enough for liquid water to persist at the surface.
- Jul 22, 2013For the first time, a snow line has been imaged in the dusty disc of a far-off, infant solar system.
- Jul 21, 2013Two new studies based on data from NASA's Curiosity rover are helping to explain how Mars lost much of its original atmosphere. Studying the atmospheric history of Mars can provide clues as to whether or not the planet could have been capable of supporting life
- Jul 19, 2013A careful analysis of Kepler-69c indicates that the planet lies just outside the inner edge of the habitable zone around its host star. This means that Kepler 69c is probably more of a Super Venus than a Super Earth.
- Jul 18, 2013A new study takes a deeper look into the fate of water on Earth-like planets that orbit red dwarf stars. Many of these exoplanets quickly become "tidally locked," with one side always facing their reddish star while the other side freezes in permanent night.
