Other more than 550 of the newly discovered planets are thought to be rocky. The last answer about how many potentially habitable planets are in the galaxy was amazing: “tens of billions of potentially habitable, Earth-like planets out in the galaxy,” Natalie Batalha, a Kepler mission scientist at NASA’s Ames Research Cente said. Kepler still has more than 2,000 candidates to analyze, about 1,300 of which are classified as “more likely planet.” The $600 million Kepler mission launched in March 2009, tasked with determining how common Earth-like planets are throughout the Milky Way. Kepler conducted its original planet hunt until May 2013, when the second of the telescope’s four orientation-maintaining reaction wheels failed. Now, the astronomers have to analyze the collected data. Kepler itself is still studying the heavens after a correction of the method was applied.
