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.

XMM-Newton discovers scorching gas in Milky Way's halo
16 January 2020

ESA's XMM-Newton has discovered that gas lurking within the Milky Way's halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.

Mapping the cosmic journey of phosphorus with Rosetta and ALMA
15 January 2020

Astronomers using the combined powers of ESA's Rosetta mission and the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) have traced the journey of phosphorus – one of life's building blocks – from star-forming regions to comets.

Huygens landing spin mystery solved
14 January 2020

Fifteen years ago today, ESA's Huygens probe made history when it descended to the surface of Saturn's moon Titan and became the first probe to successfully land on another world in the outer Solar System. However, during its descent, the probe began spinning the wrong way – and recent tests now reveal why.

First sighting of hot gas sloshing in galaxy cluster
10 January 2020

ESA's XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster – a never-before-seen behaviour that may be driven by turbulent merger events.

Switching on the CHEOPS instrument
10 January 2020

The science instrument on ESA's Characterising Exoplanet Satellite, CHEOPS, was successfully activated on 8 January, marking the beginning of the mission's in-orbit commissioning.

Hubble Surveys Gigantic Galaxy [heic2002]
6 January 2020

The NASA/ESA Hubble Space Telescope has imaged the majestic spiral galaxy UGC 2885, which may be the largest known in the local universe. It is 2.5 times wider than our Milky Way and contains 10 times as many stars.

Liftoff for CHEOPS, ESA's exoplanet mission
18 December 2019

ESA's CHEOPS mission lifted off on a Soyuz-Fregat launcher from Europe's Spaceport in Kourou, French Guiana, at 09:54:20 CET on 18 December on its exciting mission to characterise planets orbiting stars other than the Sun.

Hubble watches interstellar comet Borisov speed past the Sun [heic1922]
12 December 2019

The NASA/ESA Hubble Space Telescope has once again captured comet 2I/Borisov streaking through our Solar System on its way back into interstellar space. At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen.
