Rethinking cosmology: Universe expansion may not be uniform
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.

Hubble finds best evidence for elusive mid-size black hole [heic2005]
New data from the NASA/ESA Hubble Space Telescope have provided the strongest evidence yet for mid-sized black holes in the Universe. Hubble confirms that this "intermediate-mass" black hole dwells inside a dense star cluster.

ESA to conduct BepiColombo flyby amid coronavirus crisis
Controllers at ESA's mission control centre are preparing for a gravity-assist flyby of the European-Japanese Mercury explorer BepiColombo. The manoeuvre, which will see the mission adjust its trajectory by harnessing Earth's gravitational pull as it swings past the planet, will be performed amid restrictions ESA has implemented in response to the coronavirus pandemic.

ESA scales down science mission operations amid pandemic
In response to the escalating coronavirus pandemic, ESA has decided to further reduce on-site personnel at its mission control centre in Darmstadt, Germany.

Iron is everywhere in Earth's vicinity, suggest two decades of Cluster data
Using over 18 years of data from ESA's Cluster mission, scientists have mapped the heavy metals in the space surrounding Earth, finding an unexpected distribution and prevalence of iron and shedding light on the composition of our cosmic environment.

On the origin of massive stars [heic2004]
This scene of stellar creation, captured by the NASA/ESA Hubble Space Telescope, sits near the outskirts of the famous Tarantula Nebula. This cloud of gas and dust, as well as the many young and massive stars surrounding it, is the perfect laboratory to study the origin of massive stars.

6th Announcement of Opportunity for Science Planners in the NASA-led IRIS mission
This 6th Announcement of Opportunity (AO), open to scientists affiliated with institutes located in ESA Member States, solicits proposals for participation as Science Planners in the NASA-led IRIS mission.

Astronomers use slime mould to map the Universe's largest structures [heic2003]
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.

LISA Pathfinder lead scientist awarded prestigious prize
Professor Stefano Vitale, principal investigator of ESA's LISA Pathfinder and currently the chair of ESA's Science Programme Committee, has been honoured with the 2020 Tycho Brahe Medal for leading the ambitious mission that demonstrated technology to detect gravitational waves from space.

Milky Way's warp caused by galactic collision, Gaia suggests
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.
