Say hello to Pi Mensae c—a small, Earth-like planet located nearly 60 light-years from our Solar System. It’s probably not able to sustain life, but it’ll go down in history as the first exoplanet detected by NASA’s new TESS satellite.
Wolf 503b, a super-Earth exoplanet twice the size of Earth, is discovered orbiting Wolf 503 ru 503 145 light years away by American, German, and Canadian researchers via the NASA Kepler Space Telescope. 2018-09-6 (Context: Discoveries of exoplanets, Earth, NASA, exoplanet)
NASA astronomers use the Hubble and Spitzer space telescopes in research implying that "hot Saturn" (high surface-atmosphere temperatures and gas giant-mass) exoplanet WASP-39b, located 700 light-years from Earth, has a large amount of water molecules in its atmosphere. 2018-03-1 (Context: Discoveries of exoplanets, Earth, NASA, exoplanet)
Scientists observe the signal of iron and titanium atoms in the atmosphere of KELT-9b, an exoplanet located 600 light-years from Earth. 2018-08-15 (Context: Discoveries of exoplanets, Earth, exoplanet)
NASA's TESS exoplanet space telescope, whose launch was initially delayed, is successfully launched from Cape Canaveral Air Force Station by SpaceX on a Falcon 9 rocket. The first stage of the rocket successfully landed on SpaceX's autonomous spaceport drone ship in the Atlantic Ocean. 2018-04-18 (Context: 2018 in spaceflight, NASA, Transiting Exoplanet Survey Satellite)
SpaceX's scheduled launch of NASA's Transiting Exoplanet Survey Satellite (TESS) from Cape Canaveral Air Force Station is delayed until April 18. TESS is designed to search for exoplanets using the transit method and is 400 times more powerful than the "Kepler" space observatory. 2018-04-16 (Context: NASA, Transiting Exoplanet Survey Satellite, exoplanet)
