A brief introduction to exoplanets
12 September 2018The first discoveries of exoplanets in the 1990s completely changed our perspective of the Solar System and opened up new areas of research that continues today. With the steady rise in the number and type of known exoplanets, there is a lot to learn as we move from an era of detecting planets around other stars to one of characterising them.



First results from CHEOPS: ESA's exoplanet observer reveals extreme alien world
28 September 2020

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.

Exoplanet and cosmology discoveries awarded Nobel Prize in Physics
8 October 2019

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.

Hubble finds water vapour on habitable-zone exoplanet for the first time [heic1916]
11 September 2019

With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone by University College London (UCL) researchers in a world first.

How CHEOPS will investigate planet-hosting stars
18 July 2019As launch approaches for ESA's Characterising Exoplanet Satellite, CHEOPS, scientists are rounding off the observing plans for the mission, with the science themes of the core programme announced recently and proposals for guest observations for the first year of CHEOPS operations under evaluation.
Delivery of first detectors for PLATO's exoplanet mission
11 April 2019The first batch of charge-coupled devices, or CCDs, to be flown on ESA's PLATO space observatory was accepted by ESA last month. This is an important milestone on the road to creating a groundbreaking spacecraft that will detect Earth-sized exoplanets in orbit around nearby stars.



CHEOPS Second Announcement of Opportunity (AO-2)
4 November 2020

Proposals are solicited in response to the second Announcement of Opportunity (AO-2) for observing time in the CHEOPS Guest Observers Programme. This AO covers the period 26 March 2021 to 25 March 2022. The deadline for proposals is 1 December 2020, 13:00 CET/12:00 GMT.

CHEOPS Discretionary Programme is now open
17 July 2020

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.

CHEOPS AO-1 Programmes
24 July 2019Observing time on CHEOPS in the Guest Observers Programme has been awarded to 12 proposals received in response to the CHEOPS first Announcement of Opportunity (AO-1).

Spacecraft Testing

Spacecraft Testing

#17: Practice makes perfect for CHEOPS inflight operations
25 June 2019It takes collaboration and teamwork to operate a spacecraft. As the CHEOPS launch approaches, a Europe-wide team is preparing to take control of inflight activities once the satellite is in space.
#16: CHEOPS is ready for flight
11 March 2019Recent months on the CHEOPS mission have seen the completion of spacecraft testing and the conclusion of a very important review, which determined that the satellite is ready to fly.
#15: A jigsaw falling into place: CHEOPS end-to-end testing complete
12 February 2019After a successful series of tests, the team that will operate the CHEOPS mission is ready for the activities to follow the satellite launch later this year.
#14: CHEOPS - withstanding the sound of launch and avoiding radio interference
17 October 2018For the CHEOPS mission, September was a busy month of acoustic noise testing and Electromagnetic Compatibility (EMC) testing at ESA's technical centre in the Netherlands.
