Kepler Spacecraft Has Found a Trove of New Alien Planets

KISSIMMEE, Fla. — NASA’s Kepler spacecraft has bounced again properly from the malfunction that ended its unique exoplanet hunt greater than two years in the past.

Kepler has now found greater than one hundred confirmed alien planets throughout its second-probability K2 mission, researchers introduced Tuesday (Jan. 5) right here on the 227th Assembly of the American Astronomical Society (AAS).

The $600 million Kepler mission launched in March 2009, tasked with figuring out how generally Earth-like planets happen all through the Milky Approach galaxy. Kepler has been extremely profitable, discovering greater than 1,000 alien worlds so far, greater than half of all exoplanets ever found. [Gallery: A World of Kepler Planets]

The spacecraft finds planets by the "transit technique," noting the tiny brightness dips induced when a planet crosses its host star’s face from Kepler’s perspective. This system requires extraordinarily exact pointing, a capability Kepler misplaced in Might 2013 when the second of the observatory’s 4 orientation-sustaining response wheels failed.

However the Kepler workforce shortly found out a option to hold the telescope secure, utilizing photo voltaic radiation strain as a type of third wheel. That meant the spacecraft might eye totally different patches of the sky for round eighty days at a time to seek for planets and different cosmic our bodies and phenomena. That is what Kepler has been doing in its K2 mission, which NASA greenlit in Might 2014.

Researchers had expressed hope that K2 might decide up some further exoplanets and fascinating buildings within the sky. The prolonged mission has definitely delivered, recognizing a number of dozen confirmed planets, and now the tally will bounce dramatically.

The primary 5 K2 campaigns, which every checked out a special a part of the sky, "have produced over one hundred validated planets," Ian Crossfield, an astronomer at College of Arizona, stated Tuesday throughout a presentation on the AAS assembly. "This can be a validation of the entire K2 program’s capability to seek out giant numbers of true, bona fide planets."
