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.
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.
Controllers at ESA's mission control centre are preparing for an Earth gravity-assist flyby of the European-Japanese Mercury explorer BepiColombo. The manoeuvre will be performed amid restrictions ESA has implemented in response to the coronavirus 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. The new adjustments require temporarily stopping instrument operation and data gathering on four Solar System missions: Cluster, ExoMars TGO, Mars Express and Solar Orbiter.
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.
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.
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. The deadline for proposals is 30 April 2020, 12:00 (noon) CEST.
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.
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.
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.
