NASA is ready to reveal the latest discoveries by the powerful Kepler space telescope which scans for planets outside our solar system. The space agency says it will stream its news live on Monday, June 19, at 11am EDT. Launched in 2009, the Kepler telescope has led the search for Earth-sized planets in or around the habitable zone of other stars. So far the observatory has unearthed thousands of planets across a range of sizes. Speculation is mounting as to what NASA is preparing to announce next week, with Twitter users placing extraterrestrial life and another habitable planet on top of their wishlist. Last year, NASA announced the discovery of nine planets orbiting the star TRAPPIST-1, three of which lie inside the star's habitable zone. NASA plans to study the seven worlds using the James Webb Space Telescope.
