Don't miss the twist

1 October 2021:   Don't miss the new twist given to the CHEOPS Discretionary Programme through which proposals for observing time on CHEOPS can be submitted throughout the year. The requirement that the target of a discretionary proposal proposal be either newly discovered or newly declared to be of high scientific interest since the closing of the last annual call (1 December 2020) has been waived for proposals let by PhD students (as part of their thesis work) or early career researchers  Further details on the Discretionary Programme can be found at this link.

Unique exoplanet photobombs CHEOPS study of nearby star system

28 June 2021 While studying two exoplanets in a bright nearby star system, Nu 2 Lupi, CHEOPS unexpectedly spotted the transit of the system's third known planet. To find out more about what these observations of one of the closest Sun-like stars and one of only three naked-eye stars found to host multiple transiting planets revealed, see the web article here, and the paper by Delrez et al. 2021, published in Nature Astronomy.

Cheops observes its first exoplanets and is ready for science

16 April 2020: Cheops, ESA’s new exoplanet mission, has successfully completed its almost three months of in-orbit commissioning, exceeding expectations for its performance. The mission passed its in-orbit commissioining review on the 25 March 2020, making the handover of responsiblity for operations to the CHEOPS Mission Consortium, led by the University of Bern. The satellite, which will commence routine science operations by the end of April, has already obtained promising observations of known exoplanet-hosting stars, with many exciting discoveries to come.

A perfect blur; First image From CHEOPS

7 February 2020: CHEOPS acquired the first image of its initial target, a key milestone in the in-orbit commissioning phase. 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 in other solar systems.
