ESOcast SD

Astronomers using ALMA, in which the ESO is a partner, have revealed an extremely distant galaxy that looks surprisingly like our Milky Way. This video summarises their findings.

Astronomers using ESO's Very Large Telescope have imaged a 'space butterfly', a planetary nebula known as NGC 2899. This video offers stunning views of this object and the science behind it.

The SPHERE instrument on ESO’s Very Large Telescope has captured the first ever image of a young, Sun-like star accompanied by two giant exoplanets.

A ‘fly to’ TYC 8998-760-1

Astronomers have discovered the absence of an unstable massive star in a dwarf galaxy with ESO’s Very Large Telescope. This video offers a summary of the research.

In this ESOcast, we explore some of the many questions interstellar visitors 1I/'Oumuamua and 2I/Borisov have raised including: what are they made of? How did they form? Are they like the comets or asteroids in our Solar System? And finally, what can they reveal about other planetary systems?

Astronomers using ESO telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. This video offers a summary of the discovery.

This video lets you see some of the many things we do not understand in the Universe, and the strange and surreal paradoxes in what we think we understand…

Observations with ESO’s SPHERE instrument on the Very Large Telescope have revealed the telltale signs of a star system being born.

A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth. The black hole is closer to our Solar System than any other found to date and forms part of a triple system that can be seen with the naked eye.

ESO's Very Large Telescope has observed a star dancing around the supermassive black hole at the centre of the Milky Way. The observations have revealed, for the first time, that the star’s orbit is shaped like a rosette and not like an ellipse.

As doctors and nurses are on the frontlines, saving the lives of those infected by COVID-19, others have a role to play to prevent the disease spreading further by staying at home. This goes for ESO staff as well, including astronomers and telescope operators.

What are the strangest exoplanets ever found or studied with ESO telescopes? Watch this ESOcast to find out.

Using ESO's Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation Orion.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation between two stars. Find out more about this stellar fight in this ESOcast Light.
