XMM-Newton at 20: The fascinating X-ray universe
9 December 2019

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.

XMM-Newton at 20: The large-scale Universe
9 December 2019

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.

XMM-Newton at 20: Taking care of the science operations
9 December 2019

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.

Hubble studies gamma-ray burst with the highest energy ever seen [heic1921]
20 November 2019

New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the gamma-ray burst GRB 190114C.

Hubble captures a dozen Sunburst Arc doppelgangers [heic1920]
7 November 2019

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.

Exoplanet and cosmology discoveries awarded Nobel Prize in Physics
8 October 2019

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.

Mysteriously in-sync pulsar challenges existing theories
13 September 2019

For the first time, astronomers have detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar some 4500 light years away. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.

Unexpected periodic flares may shed light on black hole accretion
11 September 2019

ESA's X-ray space telescope XMM-Newton has detected never-before-seen periodic flares of X-ray radiation coming from a distant galaxy that could help explain some enigmatic behaviours of active black holes.

Gaia untangles the starry strings of the Milky Way
28 August 2019

Rather than leaving home young, as expected, stellar 'siblings' prefer to stick together in long-lasting, string-like groups, finds a new study of data from ESA's Gaia spacecraft.

Shedding light on white dwarfs – the future of stars like our Sun
17 May 2019ESA's Gaia mission has been busy mapping our Milky Way galaxy since 2014, and just over one year ago released its second batch of data on more than one billion stars. Since then, astronomers have been exploring this catalogue to reveal a huge amount of new information about the cosmos. One type of object that has seen an abundance of new...
Rethinking everything we thought we knew about star clusters
26 February 2019ESA's Gaia satellite is on a mission: to map and characterise more than one billion of the stars in the Milky Way. Many of these stars reside in complex, eye-catching clusters scattered throughout our Galaxy and, by studying these stellar groupings, Gaia is revealing much about the formation and evolution of stars in our cosmic home and...
