For the first time, astronomers have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a star in its close vicinity. This video summarises the discovery.
A new finding, made with the ALMA observatory, in which ESO is a partner, is shedding light on how fluorine is forged in the Universe. Find out more in this discovery, and how it is related to our dental hygiene, in this video summary.
Why do we aim for bigger and bigger telescopes, such as ESO’s Extremely Large Telescope currently under construction in Chile’s Atacama Desert? And how does the effort pay back, not only in terms of astronomical discoveries but also to the whole of s
Using ALMA, a team of astronomers have unambiguously detected a moon-forming disc around a distant planet for the first time. The planet is a Jupiter-like gas giant, hosted in a system still in the process of being formed. The result promises to shed
A team of astronomers have released colourful new observations of nearby galaxies obtained with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project
When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new research done with ESO's Very Large Telescope an
Part of the world-wide effort to scan and identify potentially dangerous asteroids and other near-Earth objects, asteroid hunter Test-Bed Telescope 2 (TBT2), a European Space Agency telescope hosted at ESO’s La Silla Observatory in Chile, has now sta
New observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pris
