NASA found new planets in the ‘habitable zone’ with liquid water on the surface
January 8, 2013
Responsible for the NASA Kepler probe announced, “the finding of 461 new candidates for planets orbiting a star in what is known as a ‘habitable zone’, with a suitable distance to host liquid water on its surface”.
According to Christopher Burke, scientific leading the research at the SETI Institute in Mountain View, California: “from May 2009 to March 2011, the results show a steady increase in the number of candidates for planets of smaller size and the number of stars with more than one candidate. There is no better way to start the beginning of the extended mission of Kepler, which began at the end of last year, which discover possible worlds with life”.
“Since the last catalogue was made public in February 2012, the number of candidates worlds discovered by Kepler increased by 20 and now stands at 2,740 possible planets orbiting 2.036 stars. “The most significant increases are observed in the number of worlds of the Earth size that grew to 43″.
“In addition, the number of discovered stars that may have more than one potential planet in its orbit is 365 to 467. 43 Of the candidates for planets may have other neighboring planets”.
“The Kepler space telescope identified planets candidates by measuring the variation of the brightness of 150,000 stars. If a planet passes or passes ahead of the host star, there will be a variation in brightness. At least three transits are required to interpret the signal as a potential planet”.
According to Steve Howell, scientific project of the Kepler Mission in NASA’s Ames Center: “scientists analyzed more than 13,000 traffic signals to eliminate false positives caused by the instrumentation of spaceships and Astrophysical phenomena.”
Candidates require other observations of tracking and analysis to be confirmed as planets. In early 2012, 33 candidates found by Kepler were confirmed as planets. Currently, there are 105. The question is not if we have a genuine twin of Earth, the question is when. The countdown already began”.
