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'.
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."
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.
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.
A global collaboration of telescopes including ESA's INTEGRAL high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy – something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery.
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.
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.
