- Jul 26, 2013A new study helps explain why so few high-mass galaxies exist. Galaxies grow when they consume gas clouds and produce stars. Now scientists have revealed that star formation also jettisons gas to the outer edge of the galaxy, 'starving' it for a period of time
- Jul 25, 2013What is life? In this interview, Gerry Joyce of the Scripps Research Institute reveals why it’s been so hard for scientists to come up with a definition that encompasses the multiple dimensions of life as we know it.
- 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
