KOI-872
(Preview)
KOI-872: Timing is Everything It's no surprise that the techniques we're using to look for moons around exoplanets should start turning up new planets on their own. We're still looking for that first exomoon, but a team of researchers working with the Hunt for Exomoons with Kepler (HEK) project ha...

HD 10180
(Preview)
Discovery of a new planetary system similar to the Solar System A group of European astronomers has discovered a planetary system with at least five planets, but it could have two more, around a sun-like star, HD 10180. The number of planets and their distances from the star makes this system resemb...

Runaway Planets
(Preview)
Runaway Planets Zoom at a Fraction of Light-Speed Seven years ago, astronomers boggled when they found the first runaway star flying out of our Galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: If a star can get tossed outward at such an extreme velocit...

First Earth-sized planets spotted Astronomers have detected the first Earth-sized planets, which are orbiting a star similar to our own Sun. In the distant past they may have been able to support life and one of them may have had conditions similar to our own planet - a so-called Earth-twin - accordi...
