The first true alien Earth may not elude planet hunters for much longer. Last week, astronomers announced that NASA's Kepler space telescope had discovered eight more relatively small planets that may be capable of hosting life as we know it, describing two of the new finds as the most Earth-like alien worlds known. Mission scientists also announced 554 new unconfirmed Kepler "planet candidates"; six of these potential worlds orbit sunlike stars, are close to Earth-size and are possibly habitable. "These candidates represent the closest analogues to the Earth-sun system found to date," said Fergal Mullally of the Kepler Science Office.
This is what Kepler has been looking for. We are now closer than we have ever been to finding a twin for the Earth around another star!
