New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought.

Hubble observes aftermath of massive collision [heic2006]
20 April 2020

What astronomers thought was a planet beyond our solar system, has now seemingly vanished from sight. Astronomers now suggest that a full-grown planet never existed in the first place.

CHEOPS observes its first exoplanets and is ready for science
16 April 2020

CHEOPS, ESA's new exoplanet mission, has successfully completed its almost three months of in-orbit commissioning, exceeding expectations for its performance.

Rethinking cosmology: Universe expansion may not be uniform
8 April 2020

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA's XMM-Newton, NASA's Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong.

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.

CHEOPS Discretionary Programme is now open
17 July 2020

Proposals are invited for the CHEOPS Discretionary Programme, an element of the Guest Observers Programme which enables scientists to propose observations of individual targets that have been discovered, or declared to be of high scientific merit, since the close of AO-1 back in mid-May 2019.

JWST Cycle 1 Proposal Schedule Update
1 June 2020

The uncertainties resulting from COVID-19 continue to impact the Cycle 1 schedule. STScI, NASA, ESA, and CSA have decided to delay announcing a formal schedule for JWST Cycle 1 GO/AR proposals. A further update on the schedule is anticipated in mid- to late-July.

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...
