Using ESO’s Very Large Telescope, barium has been detected in the atmosphere of two exoplanets.

The black hole police, a team of astronomers known for debunking black hole discoveries, reported finding a "needle in a haystack". After searching nearly 1000 stars outside our galaxy, they found that one of them has a stellar-mass black hole as a companion. This short video summarises the discovery.

What does it take to capture an image of the black hole at the centre of our galaxy? This video explains how the Event Horizon Telescope (EHT) works, and how astronomers managed to create one massive Earth-sized telescope big enough to “see” at the edge of black holes.

Astronomers have discovered a new type of explosion occurring on white dwarf stars in two-star systems. This video summarises the discovery.

How do the ingredients for life end up on planets? The discovery of the largest molecule ever found in a planet-forming disc is providing clues.

One team found a black hole, the other challenged their results. This is the story of how they got together to find out who was right.
