The Search for Extra Terrestrial Intelligence (SETI) has announced that it is back in business checking out the new habitable exoplanets recently discovered by NASA's Kepler space telescope to see if they might be home to alien civilisations. The cash needed to restart SETI's efforts has come in part from the US Air Force Space Command, who are interested in using the organisation's detection instruments for "space situational awareness".
Spied by NASA’s Kepler space telescope , Kepler-22b marks the best candidate yet for a life-bearing world beyond our solar system, project scientists said Monday. If it has a surface, it ought to have a nice temperature,” said Kepler’s lead scientist, Bill Borucki , during a teleconference Monday.
RELEASE : 11-408 NASA's Kepler Confirms Its First Planet in Habitable Zone of Sun-Like Star MOFFET FIELD, Calif. -- NASA's Kepler mission has confirmed its first planet in the "habitable zone," the region where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count.
Kepler-22b -- Comfortably Circling within the Habitable Zone
Closer to Finding an Earth
NASA scientists have identified a new planet they believe to have several similarities to Earth. Kepler-22b , named for the Kepler planet-hunting telescope it was spotted with, is the first planet to be confirmed beyond our solar system in what the Guardian called the "Goldilocks zone:" not too hot, not too cold, and therefore possibly habitable. The planet is 2.4 times the size of Earth.
The planet, Kepler-22b, is about twice the size of Earth and may have a surface temperature of around 22C - similar to a warm spring day in the UK.
Kepler-22b is an extrasolar planet orbiting G-type star Kepler-22 . [ 7 ] [ 8 ] It is located 600 light years away from Earth in the constellation of Cygnus . It was discovered by NASA 's Kepler Space Telescope and is the first known transiting planet to orbit within the habitable zone of a Sun-like star . [ 7 ] [ 8 ]
