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.
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 European Space Agency (ESA) and the Japanese Aerospace Exploration Agency's Institute of Space and Astronautical Science (ISAS/JAXA) have announced their decision to no longer consider the infrared space observatory, SPICA, as a candidate for the upcoming selection as ESA's 5th medium-class mission in its Cosmic Vision...
ESA's Science Programme Committee has confirmed the continued operations of five missions led by ESA's Science Programme: Cluster, Gaia, INTEGRAL, Mars Express, and XMM-Newton, from 1 January 2021 to 31 December 2022. The SPC also confirmed the Science Programme's contributions to the extended operations of Hinode, Hubble Space Telescope,...
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.
The development of ESA's JUpiter ICy moons Explorer (JUICE) is continuing apace and has hit milestones in recent months: the spacecraft's 10.6-metre-long boom is now attached, many instruments have been integrated, and the mission's high-gain antenna has arrived and undergone rigorous vibration testing.
All ten flight model solar panels for ESA's JUICE spacecraft have been delivered to Airbus Defence and Space Netherlands ready to be integrated into solar wings. The solar panels, with a total area of 85 m², are a key element of the mission, providing the necessary power to run the spacecraft and operate the science instruments.
Despite certain operational difficulties caused by the COVID-19 pandemic, the assembly and integration of the flight model for ESA's JUpiter ICy moons Explorer (JUICE) spacecraft has continued with few delays during the first six months of the year.
