XMM-Newton reveals giant flare from a tiny star
20 February 2020

A star of about eight percent the Sun's mass has been caught emitting an enormous 'super flare' of X-rays – a dramatic high-energy eruption that poses a fundamental problem for astronomers, who did not think it possible on stars that small.

First Solar Orbiter instrument sends measurements
17 February 2020

First measurements by a Solar Orbiter science instrument reached the ground on Thursday, providing a confirmation to the international science teams that the magnetometer on board is in a good shape following a successful deployment of the spacecraft's instrument boom.

Liftoff for Solar Orbiter, ESA's mission to face the Sun up close
10 February 2020

ESA's Solar Orbiter mission lifted off on an Atlas V 411 from Cape Canaveral, Florida, at 05:03 CET on 10 February on its mission to study the Sun from new perspectives.

A perfect blur – First image by exoplanet watcher CHEOPS
7 February 2020

ESA's exoplanet-observer CHEOPS acquired the first image of its initial target star, following the successful telescope cover opening on 29 January 2020.

ESA starts definition phase for Comet Interceptor
6 February 2020

Following an internal assessment of the results of the phase 0 studies, the European Space Agency is moving forward starting the Definition Phase (phase A) for the F-class mission Comet Interceptor.

Rosetta and the chameleon comet
5 February 2020

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.

CHEOPS opens its eye to the sky
29 January 2020

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.

Global Gaia campaign reveals secrets of stellar pair
21 January 2020

A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.

Building blocks of life spotted on Rosetta's comet hint at composition of its birthplace
20 January 2020

Observations from ESA's Rosetta spacecraft are shedding light on the mysterious make-up of Comet 67P/Churyumov-Gerasimenko, revealing a mix of compounds thought to be essential precursors to life – including salts of ammonium and a particular type of hydrocarbons.

XMM-Newton maps black hole surroundings
20 January 2020

Material falling into a black hole casts X-rays out into space – and now, for the first time, ESA's XMM-Newton X-ray observatory has used the reverberating echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself.
