#KEPLER GLIMPSES PLANETS VERIFICATION#
The exoplanets were found using a statistical technique called " verification by multiplicity". On February 26, 2014, NASA announced the discovery of 715 newly verified exoplanets around 305 stars by the Kepler Space Telescope. Kepler has also measured the reflected light from some planets already known, discovering planets undetectable with the transit method as well as improving knowledge of the characteristics of planets already discovered. In addition, gravitational microlensing has been proposed as a method of using Kepler to detect compact objects, such as white dwarfs, neutron stars, and black holes. Since the launch of the spacecraft, though, both the Kepler team at NASA and independent researchers have found new ways of detecting planets, including the use of the transit timing variation method and relativistic beaming. Kepler, launched on March 7, 2009, was designed to observe a fixed portion of the sky in visible light and measure the light curves of the various stars in its field of view, looking for planets crossing in front of their host stars via the transit method. Public Kepler data has also been used by groups independent of NASA, such as the Planet Hunters citizen-science project, to detect several planets orbiting stars collectively known as Kepler Objects of Interest. In addition to detecting planets itself, Kepler has also uncovered the properties of three previously known extrasolar planets. In addition, Kepler has detected over 3,601 unconfirmed planet candidates and 2,165 eclipsing binary stars. As of 2018, the Kepler space telescope and its follow-up observations have detected 2,398 confirmed planets, including hot Jupiters, super-Earths, circumbinary planets, and planets located in the circumstellar habitable zones of their host stars. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
