The Kepler space telescope is a defunct space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine and a half years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018.
Kepler-7b is one of the first five exoplanets to be confirmed by NASA's Kepler spacecraft, and was confirmed in the first 33.5 days of Kepler's science operations. It orbits a star slightly hotter and significantly larger than the Sun that is expected to soon reach the end of the main sequence. Kepler-7b is a hot Jupiter that is about half the mass of Jupiter, but is nearly 1.5 times its size; at the time of its discovery, Kepler-7b was the second most diffuse planet known, surpassed only by WASP-17b. It orbits its host star every five days at a distance of approximately 0,06 AU. Kepler-7b was announced at a meeting of the American Astronomical Society on January 4, 2010. It is the first extrasolar planet to have a crude map of cloud coverage.
Kepler-22b is an exoplanet orbiting within the habitable zone of the Sun-like star Kepler-22. It is located about 640 light-years from Earth in the constellation of Cygnus. It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. Kepler-22 is too dim to be seen with the naked eye.

William J. (Bill) Borucki is a space scientist who worked at the NASA Ames Research Center. Upon joining NASA in 1962, Borucki joined the group conducting research on the heat shield for Apollo program spacecraft. He later turned his attention to the optical efficiency of lightning strikes in the atmospheres of planets, investigating the propensity that these lightning strikes could create molecules that would later become the precursors for life. Subsequently, Borucki's attention turned to extrasolar planets and their detection, particularly through the transit method. In light of this work, Borucki was named the principal investigator for NASA's Kepler space telescope mission, launched on March 7, 2009 and dedicated to a transit-based search for habitable planets. In 2013, Borucki was awarded the United States National Academy of Sciences's Henry Draper Medal for his work with Kepler. In 2015 he received the Shaw Prize in Astronomy.
Kepler-62f is a super-Earth exoplanet orbiting within the habitable zone of the star Kepler-62, the outermost of five such planets discovered around the star by NASA's Kepler space telescope. It is located about 980 light-years from Earth in the constellation of Lyra.
Kepler-138, also known as KOI-314, is a red dwarf located in the constellation Lyra, 219 light years from Earth. It is located within the field of vision of the Kepler spacecraft, the satellite that NASA's Kepler Mission used to detect planets transiting their stars.
Kepler-438b is a confirmed near-Earth-sized exoplanet. It is likely rocky. It orbits on the inner edge of the habitable zone of a red dwarf, Kepler-438, about 472.9 light-years from Earth in the constellation Lyra. It receives 1.4 times our solar flux. The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. NASA announced the confirmation of the exoplanet on 6 January 2015.
The Nexus for Exoplanet System Science (NExSS) initiative is a National Aeronautics and Space Administration (NASA) virtual institute designed to foster interdisciplinary collaboration in the search for life on exoplanets. Led by the Ames Research Center, the NASA Exoplanet Science Institute, and the Goddard Institute for Space Studies, NExSS will help organize the search for life on exoplanets from participating research teams and acquire new knowledge about exoplanets and extrasolar planetary systems.
Kepler-452b is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope. It is located about 1,400 light-years (430 pc) from Earth in the constellation of Cygnus.
Sarah Ballard is an American astronomer who is a professor at the University of Florida. She has been a Torres Fellow at the Massachusetts Institute of Technology, a L'Oreal Fellow, and a NASA Carl Sagan Fellow.
Kepler-1229b is a confirmed super-Earth exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf Kepler-1229, located about 870 light years from Earth in the constellation of Cygnus. It was discovered in 2016 by the Kepler space telescope. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
Elisa Victoria Quintana is a scientist working in the field of astronomy and planetary science at NASA Goddard Space Flight Center. Her research focuses the detection and characterization of exoplanets in addition to studying how they form. She is best known for the detection of Kepler 186f, the first Earth-sized planet found in the habitable zone of a star other than the Sun.
Aomawa L. Shields is an associate professor of physics and astronomy at UC Irvine. Her research is focused on exploring the climate and habitability of small exoplanets, using data from observatories including NASA's Kepler space telescope. Shields was a 2015 TED Fellow, and is active in science communication and outreach. She develops interactive workshops to encourage self-esteem and teach about astronomy, combines her training in theater and her career in astronomy.
Jessie Christiansen is an Australian astrophysicist who is the Chief Scientist of the NASA Exoplanet Science Institute at the California Institute of Technology (Caltech). She won the 2018 NASA Exceptional Engineering Achievement Medal for her work on the Kepler planet sample.
WASP-39b, officially named Bocaprins, is a "hot Jupiter" extrasolar planet discovered in February 2011 by the WASP project, notable for containing a substantial amount of water in its atmosphere. In addition WASP-39b was the first exoplanet found to contain carbon dioxide in its atmosphere, and likewise for sulfur dioxide.
Kepler-1658b is a hot Jupiter, a type of gas giant exoplanet, that orbits an F-type star called Kepler 1658, located about 2629 light-years away from the Solar System. It is the first planet identified by the Kepler space telescope after its launch in 2009, but later ruled out as false alarm since its transit could not be confirmed. A study published in 2019 established it as a planet, describing it as "the closest known planet in terms of orbital period to an evolved star." Analysis of the Transiting Exoplanet Survey Satellite (TESS) data in 2022 showed that it is gradually spiraling into its star.
LHS 475 b is a terrestrial planet orbiting the star LHS 475 which is about 40.7 light years away, in the constellation of Octans. It was the first extrasolar planet to be confirmed by the James Webb Space Telescope. It completes an orbit every 2 days and is 99% the diameter of Earth. It is also one of the most similar-to-Earth exoplanets discovered, in terms of radius.
