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."

Solar Orbiter's latest results show that the mission is making the first direct connections between events at the solar surface and what's happening in interplanetary space around the spacecraft. It is also giving us new insights into solar 'campfires', space weather and disintegrating comets.

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.

The ESA-NASA Solar and Heliospheric Observatory (SOHO) is celebrating its twenty-fifth launch anniversary.

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.
