Most Planetary Systems are 'Flatter than Pancakes'
Oct 18, 2012 (SPX)
Our solar system looks like many others, "flatter than pancakes," report UCLA astronomers who were able to statistically determine the properties of planetary s...
Nearest Star Has Earth Mass Planet
Oct 17, 2012 (ESO)
European astronomers have discovered a planet with about the mass of the Earth orbiting a star in the Alpha Centauri system - the nearest to Earth. It is also t...
Ultra-Compact Planetary System Is A Touchstone For Understanding New Planet Population
Oct 16, 2012 (SPX)
