Astronomers have used ESO telescopes to detect at least 70 rogue planets in our Milky Way, the largest group to date. Learn more about these elusive cosmic nomads in this video summarising the discovery!

To learn more about the Milky Way's supermassive black hole, Sgr A*, scientists zoomed in towards our galaxy's centre with the help of ESO's Very Large Telescope Interferometer to watch how stars move around Sgr A*. This video summarises what they found.

ESO’s Very Large Telescope has captured an image of a planet orbiting b Centauri, a pair of stars that can be seen with the naked eye. Find out why this next-door planetary system is extreme in this short video.

Using the ESO’s Very Large Telescope, astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. This video summarises the discovery.

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.

Astronomers have used the ESO’s Very Large Telescope in Chile to image 42 of the biggest main-belt asteroids. Meet some of the 42 in this video summarising the discovery!

A team of astronomers have used ESO’s Very Large Telescope in Chile to shed new light on planets around a nearby star that resemble those in the inner Solar System. This video summarises what they found about the planetary system, called L 98-59.

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 society? Four special guests have answered these questions, so fasten your belt and get ready for a breathtaking discovery journey in the world of big telescopes!

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 new light on how moons and planets form in young stellar systems. This video summarises the discovery.
