VISTA unveils a new image of the Large Magellanic Cloud
ESO’s VISTA telescope reveals a remarkable image of the Large Magellanic Cloud, one of our nearest galactic neighbours. VISTA has been surveying this galaxy and its sibling the Small Magellanic Cloud, as well as their surroundings, in...
Interstellar 2.0
Astronomers have spotted an object that looks likely to be a very rare visitor from outside our Solar System. If confirmed, this unusual body would be only the second interstellar object ever detected passing through our...
Exciting exoplanet
Hubble finds water vapour on habitable-zone exoplanet for the first time, paving the way for future discoveries by the James Webb Space Telescope and the Ariel mission
First Earth observation satellite with AI ready for launch
A few months from now will see the launch of the first European satellite to demonstrate how onboard artificial intelligence can improve the efficiency of sending Earth observation data back to Earth. Dubbed ɸ-Sat, or PhiSat, this...
Unexpected periodic flares may shed light on black hole accretion
ESA’s X-ray space telescope XMM-Newton has detected never-before-seen periodic flares of X-ray radiation coming from a distant galaxy that could help explain some enigmatic behaviours of active black holes.
Destination Mars
