| 'Post-mortem' yields insight into Kepler's supernova Posted: 08 Apr 2013 03:46 PM PDT An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led Suzaku satellite. The findings will help astronomers better understand the diversity of type Ia supernovae, an important class of stellar explosion used in probing the distant universe. |
| How carbon moves within planet plays big role in planetary atmosphere formation Posted: 08 Apr 2013 12:29 PM PDT A new study suggests that the way carbon moves from within a planet to the surface plays a big role in the evolution of a planet's atmosphere. Mars, which likely released much of its carbon as methane, might have been warm enough to support liquid water. |
| NASA selects Explorer investigations for formulation Posted: 08 Apr 2013 02:52 AM PDT NASA's Astrophysics Explorer Program has selected two missions for launch in 2017: a planet-hunting satellite and an International Space Station instrument to observe X-rays from stars. |
| TESS project will launch telescopes to perform full-sky search for transiting exoplanets Posted: 08 Apr 2013 02:50 AM PDT NASA has selected the Transiting Exoplanet Survey Satellite (TESS) project for a planned launch in 2017. The $200 million project will use an array of wide-field cameras to perform an all-sky survey to discover transiting exoplanets, ranging from Earth-sized planets to gas giants, in orbit around the brightest stars in the sun's neighborhood. |
