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.
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.
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.
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.
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.
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.
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.
On 10 December 1999, as XMM-Newton launched from Europe's spaceport in Kourou, French Guiana, no one was expecting that the mission would last for two decades.
During its 20 years in space, ESA's XMM-Newton X-ray observatory has made many exciting discoveries. But no one could have predicted that the very first observation of the spacecraft would be one of its most important.
ESA's X-ray observatory, XMM-Newton, has now spent 20 years in orbit. In those two decades it has made many scientific breakthroughs, helping bring X-ray astronomy into the main stream of astronomical investigation.
New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the gamma-ray burst GRB 190114C.
Data from ESA's Cluster mission has provided a recording of the eerie 'song' that Earth sings when it is hit by a solar storm.
Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times on the night sky. This unique sight, created by strong gravitational lensing, helps astronomers get a better understanding of the cosmic era known as the epoch of reionisation.
In celebration of Halloween, this new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face. This observation was made on 19 June 2019 in visible light by the telescope's Advanced Camera for Surveys.
ESA's Solar Orbiter mission has completed its test campaign in Europe and is now being packed ready for its journey to Cape Canaveral at the end of this month, ahead of launch in February 2020.
On 12 October 2019, the NASA/ESA Hubble Space Telescope provided astronomers with their best look yet at an interstellar visitor – Comet 2I/Borisov – which is believed to have arrived here from another planetary system elsewhere in our galaxy.
ESA congratulates 2019 Nobel Prize in Physics laureates Michel Mayor and Didier Queloz, who have been awarded the prestigious prize for the first discovery of an exoplanet orbiting a solar-type star, and James Peebles, honoured for the theoretical framework of cosmology used to investigate the Universe on its largest scales.
Scientists analysing data from the Cassini mission have found evidence of light, soluble and reactive organic molecules in the ice grains ejected by Saturn's icy moon Enceladus, providing another important piece of evidence to investigate its potential habitability.
The NASA/ESA Hubble Space Telescope has produced a new resource for astronomers: the Hubble Catalog of Variables (HCV), which is the first full, homogeneous catalogue of variable sources based on archival data from the iconic observatory.
Scientists analysing the treasure trove of images taken by ESA's Rosetta mission have turned up more evidence for curious bouncing boulders and dramatic cliff collapses.
