ESA Science & Technology - Exoplanets
A brief introduction to exoplanets
Unique exoplanet photobombs CHEOPS study of nearby star system
While exploring two exoplanets in a bright nearby star system, ESA's exoplanet-hunting CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet "with no known equivalent", say the researchers.
ESA's exoplanet watcher CHEOPS reveals unique planetary system
ESA's exoplanet mission CHEOPS has revealed a unique planetary system consisting of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star. The sizes and masses of the planets, however, don't follow such an orderly pattern.
Ariel moves from blueprint to reality
ESA's exoplanet mission Ariel, scheduled for launch in 2029, has moved from study to implementation phase, following which an industrial contractor will be selected to build the spacecraft.
First results from CHEOPS: ESA's exoplanet observer reveals extreme alien world
ESA's new exoplanet mission, CHEOPS, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates CHEOPS' unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.
James Webb Space Telescope to launch in October 2021
The launch of the NASA/ESA/CSA James Webb Space Telescope (Webb) on an Ariane 5 rocket from Europe's Spaceport in French Guiana is now planned for 31 October 2021.
Exoplanet and cosmology discoveries awarded Nobel Prize in Physics
ESA congratulates 2019 Nobel Prize in Physics laureates Michel Mayor and Didier Queloz, who have been awarded the prestigious prize for the first discovery of an exoplanet orbiting a solar-type star, and James Peebles, honoured for the theoretical framework of cosmology used to investigate the Universe on its largest scales.
CHEOPS AO-2 Programmes
Observing time on CHEOPS in the Guest Observers Programme has been awarded to nine proposals received in response to the CHEOPS second Announcement of Opportunity (AO-2).
CHEOPS Discretionary Programme is now open
Proposals are invited for the CHEOPS Discretionary Programme, an element of the Guest Observers Programme which enables scientists to propose observations of individual targets that have been discovered, or declared to be of high scientific merit, since the close of AO-1 back in mid-May 2019.
