The CHEOPS Time Allocation Committee (TAC) met on 11 - 13 May 2022 to review proposals submitted to the third and final annual Announcement of Opportunity (AO-3) for observing time in ESA's CHEOPS Guest Observers Programme during the nominal mission.

Proposals are solicited in response to the third, and final, Announcement of Opportunity (AO-3) for observing time in the CHEOPS Guest Observers Programme during the nominal mission. This AO covers the period from 1 July 2022 to 24 September 2023.

The third annual announcement of opportunity (AO-3) for participation in the CHEOPS Guest Observers Programme was due to open on 9 November 2021. The AO has been postponed and is currently foreseen to come out in early 2022.

The international James Webb Space Telescope has passed the final mission analysis review for its launch on an Ariane 5 rocket from Europe's Spaceport in French Guiana.

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.

Thanks to ESA's star mapping spacecraft Gaia and machine learning, astronomers have discovered 12 quasars whose light is so strongly deflected by foreground galaxies that they are each visible as four distinct images, called an 'Einstein cross'.

The General Observer scientific observations for the NASA/ESA/CSA James Webb Space Telescope's first year of operation have been selected. Proposals from ESA member states comprise 33% of the total number of selected proposals and correspond to 30% of the available telescope time on Webb.

Key technology for ESA's exoplanet-hunting PLATO spacecraft has passed a trial by vacuum to prove the mission will work as planned. This test replica of an 80-cm high, 12-cm aperture camera spent 17 days inside a thermal vacuum chamber.

Proposals are solicited for observations with INTEGRAL in response to the nineteenth Announcement of Opportunity, AO-19, issued 1 March 2021. This AO covers the period January 2022 to December 2022. The deadline for proposals is 9 April 2021, 14:00 CEST.

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).

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.

The optical and infrared instruments of Euclid, ESA's mission to study dark energy and dark matter in space, have passed their qualification and acceptance reviews and are now fully integrated into the spacecraft's payload module.

The 11-Jupiter-mass exoplanet called HD 106906 b occupies an unlikely orbit around a double star 336 light-years away and it may be offering clues to something that might be much closer to home: a hypothesized distant member of our Solar System dubbed "Planet Nine."

Astronomers have caught a rare glimpse of a rapidly fading shroud of gas around an aging star. Archival data from the NASA/ESA Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades.

The motion of stars in the outskirts of our galaxy hints at significant changes in the history of the Milky Way. This and other equally fascinating results come from a set of papers that demonstrate the quality of ESA's Gaia Early third Data Release (EDR3), which is made public today.

New data from the NASA/ESA Hubble Space Telescope provides further evidence for tidal disruption in the galaxy NGC 1052-DF4. This result explains a previous finding that this galaxy is missing most of its dark matter.

Today, ESA is celebrating the 25^th anniversary of the launch of the Infrared Space Observatory, ISO, with a brand new interface to the mission's unique legacy archive.

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.

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.

The NASA/ESA's Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away. Supernovae like this one can be used as cosmic tape measures, allowing astronomers to calculate the distance to their galaxies.
