Currently crossing the skies above Earth, Comet C/2020 F8 (SWAN) has the potential to become a more prominent naked eye object by late May or early June. Yet it wasn't discovered by someone looking up at the night sky.
Science instruments aboard the European-Japanese Mercury explorer BepiColombo are in excellent condition to gather high-quality data during the spacecraft's long cruise to Mercury despite not having been designed for this purpose, teams collaborating on the mission learned during the spacecraft's April flyby of Earth.
The NASA/ESA Hubble Space Telescope has provided astronomers with the sharpest view yet of the breakup of Comet C/2019 Y4 (ATLAS). The telescope resolved roughly 30 fragments of the fragile comet on 20 April and 25 pieces on 23 April.
The NASA/ESA Hubble Space Telescope’s iconic images and scientific breakthroughs have redefined our view of the Universe. To commemorate three decades of scientific discoveries, this image is one of the most photogenic examples of the many turbulent stellar nurseries the telescope has observed during its 30-year lifetime.
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, ESA's new exoplanet mission, has successfully completed its almost three months of in-orbit commissioning, exceeding expectations for its performance.
The ESA/JAXA BepiColombo mission completed its first flyby on 10 April, as the spacecraft came less than 12 700 km from Earth's surface at 06:25 CEST, steering its trajectory towards the final destination, Mercury.
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.
Proposals are solicited for observations with INTEGRAL in response to the Eighteenth Announcement of Opportunity, AO-18, issued 2 March 2020. This AO covers the period January to December 2021. The deadline for proposals has been postponed to 4 May, 14:00 CEST.
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.
First measurements by a Solar Orbiter science instrument reached the ground on Thursday, providing a confirmation to the international science teams that the magnetometer on board is in a good shape following a successful deployment of the spacecraft's instrument boom.
