Kepler Marks Five Years In Space
Five years ago today, on March 6, 2009, NASA’s Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds.
Since then, Kepler has unveiled a whole new side of our galaxy — one that is teeming with planets. Because of Kepler we now know that most stars have planets, Earth-sized planets are common, and planets quite unlike those in our solar system exist.
By analyzing Kepler data, scientists have identified more than 3,600 candidates believed to be planets, and verified that 961 of those candidates actually are planets, many as small as Earth. Discoveries made using Kepler now account for more than half of all the known exoplanets.
“During the last five years, Kepler has produced results needed to take the next big step forward in humankind’s search for life in our galaxy— providing information needed for future missions that will ultimately determine the atmospheric composition of Earth-sized exoplanets to discover if they could be habitable,” said William Borucki, Kepler principal investigator at NASA’s Ames Research Center in Moffett Field, Calif.
