Astronomers use slime mould to map the Universe's largest structures [heic2003]
10 March 2020

The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.

Milky Way's warp caused by galactic collision, Gaia suggests
2 March 2020

Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water.

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.

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.

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.

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...
