FaviconTwo planets spotted forming around a young star | ESO News 24 Mar 2026, 9:00 am

Using ESO’s Very Large Telescope (VLT), astronomers have observed two exoplanets forming around the young star WISPIT 2. Both planets are gas giants, more massive than Jupiter, and are carving out gaps in the disc of gas and dust around their host star. The WISPIT 2 system could therefore resemble a young Solar System. This video summarises the discovery.

FaviconAn unexpected shock wave | ESO News 12 Jan 2026, 5:00 am

Astronomers are surprised by a mysterious shock wave around the dead star RXJ0528+2838, studied with ESO’s Very Large Telescope. The dead star moves through space creating a so-called bow shock, as the surrounding material is pushed away. Structures like this one are typically caused by a strong outflow from the star. However, in the case of RXJ0528+2838, no known mechanism could be causing the outflow. A hidden energy source, perhaps magnetic fields, might be the answer to this mystery.

FaviconWhat’s the true shape of a supernova? | ESO News 12 Nov 2025, 2:00 pm

Astronomers have observed a supernova just a day after it was first detected. In the early stages of the blast, the explosion has not yet interacted with the material around the star, retaining its true shape. This initial shape has now been revealed for the first time. This video summarises the discovery.

FaviconRogue planet found growing at record rate | ESO News 2 Oct 2025, 8:00 am

Astronomers have found an intense ‘growth spurt’ in a rogue planet –– a planet that doesn’t orbit a star. Observations with ESO’s Very Large Telescope (VLT) reveal that this free-floating planet is eating up gas and dust from its surroundings at a rate of six billion tonnes a second, the strongest ever found for a planet of any kind. This video summarises the discovery.

FaviconHayabusa2’s next target is smaller and faster than we thought | ESO News 18 Sep 2025, 5:00 am

Astronomers have discovered that the next target for Japan’s Hayabusa2 spacecraft, the asteroid 1998 KY26, is almost three times smaller than previously thought, and spinning much faster than expected. This study was conducted using ESO’s Very Large Telescope, and its results offer important new information for the upcoming mission, just six years out from the spacecraft’s encounter with this tiny asteroid.
