ICON (Explorer 96) →. Wikinews has related news: NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite ( TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [ 6]
CHEOPS (CHaracterising ExOPlanets Satellite) is a European space telescope.Its objective is to determine the size of known extrasolar planets, which will allow the estimation of their mass, density, composition and their formation.
PLATO. PLAnetary Transits and Oscillations of stars ( PLATO) is a space telescope under development by the European Space Agency for launch in 2026. [ 4] The mission goals are to search for planetary transits across up to one million stars, and to discover and characterize rocky extrasolar planets around yellow dwarf stars (like the Sun ...
Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color. [7]
CoRoT. CoRoT (French: Convection, Rotation et Transits planétaires; English: Co nvection, Ro tation and planetary T ransits) was a space telescope mission which operated from 2006 to 2013. The mission's two objectives were to search for extrasolar planets with short orbital periods, particularly those of large terrestrial size, and to perform ...
2026 (Ariane 62) To search for and characterize rocky planets around stars like our own. 4 (+4 goal) years. ARIEL. 2029 (Ariane 62) Observe exoplanets using the transit method, study and characterise the planets' chemical composition and thermal structures. 4 years.
Animation showing exoplanets by year from 1991 until 2022 (March) with a total of 5005 discoveries. [ 1] An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016; no planet discovery has yet come from that evidence. [ 2]
The Kepler space telescope is a defunct space telescope launched by NASA in 2009 [ 5] to discover Earth-sized planets orbiting other stars. [ 6][ 7] Named after astronomer Johannes Kepler, [ 8] the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki.
