Image: Image of HD 70843, the star chosen as the first target for Cheops, ESA’s Characterising ExOPlanet Satellite. The star, located around 150 light years away in the constellation of Cancer, is visible at the centre of the image, surrounded by fainter stars in the background. The peculiar shape of the stars in the image […]

A perfect blur – First image by exoplanet watcher Cheops
ESA’s exoplanet-observer Cheops acquired the first image of its initial target star, following the successful telescope cover opening on 29 January 2020. The intentionally blurry image is a product of the specially designed telescope optics, which are deliberately defocused to maximise the precision of Cheops’ measurements and enable its unprecedented study of exoplanets, or planets […]
Rosetta and the chameleon comet
A grand synthesis of Rosetta data has shown how its target comet repeatedly changed colour during the two years it was watched by the spacecraft. The chameleon comet’s nucleus became progressively less red as it made its close pass around the Sun, and then red again as it returned to deep space. To source

Solar Orbiter operations simulations
Video: 00:03:15 ESA’s Solar Orbiter is getting ready for its launch on an Atlas V rocket provided by NASA and operated by United Launch Alliance from Cape Canaveral, Florida. Once in space, and over the course of several years, the spacecraft will repeatedly use the gravity of Venus and Earth to raise its orbit above […]
Solar Orbiter launch to the Sun
Video: 00:02:27 ESA’s Solar Orbiter mission takes a closer look at the Sun than any European satellite before. The sophisticated probe, carrying ten instruments for imaging the surface of our star and measuring the properties of the environment in its vicinity, can be seen in this animation going through parts of the launch and activation […]
Cheops launch preparations
Video: 00:03:14 This timelapse video shows the preparations for the launch of ESA’s Cheops, the Characterising Exoplanet Satellite, at Europe’s Spaceport in Kourou, French Guiana. The video spans about three weeks, starting on 28 November 2019 and ending on 18 December with the liftoff. Over this period, the fully integrated and fuelled spacecraft was fitted […]
Cheops opens its eye to the sky
Six weeks after the launch of Cheops, ESA’s Characterising Exoplanet Satellite, the telescope cover was opened as part of the mission’s in-orbit commissioning. To source
Solar Orbiter solar array deployment
Image: Artist’s impression of Solar Orbiter following launch and separation, with its solar arrays deployed. The instrument boom and antennas have not been deployed at this stage. Solar Orbiter is a space mission of international collaboration between ESA and NASA. Its mission is to perform unprecedented close-up observations of the Sun and from high latitudes, […]
