"That is a conservative estimate. There could be more."Scientists focus on M-dwarfs, he said, because the orbit of planets around M-dwarfs is very short,[url=http://www.supratksocietyvip.com/]supra skytop[/url], which allows scientists to gather data on a greater number of orbits in a shorter period of time than can be gathered on Sun-like stars.M-dwarfs are also more common than stars like the Earth's sun, which means more of them can be observed, he said."The average distance to the nearest potentially habitable planet is about seven light years. That is about half the distance of previous estimates," Kopparapau said his analysis suggested. "There are about eight cool stars within 10 light-years, so conservatively, we should expect to find about three Earth-size planets in the habitable zones." "This means Earth-sized planets are more common than we thought, and that is a good sign for detecting extraterrestrial life."</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
