Using ESO’s Very Large Telescope, astronomers have found a metal ‘scar’ imprinted on the surface of a dead star. This video summarises the discovery.

Astronomers have characterised the most luminous quasar observed to date, which is powered by the fastest-growing black hole. This black hole is growing in mass by the equivalent of one Sun per day. The matter being pulled in toward this black hole forms a disc that measures seven light-years in diameter — about 15 000 times the distance from the Sun to the orbit of Neptune.

Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the Universe — black holes and neutron stars. This video summarises the discovery.

Using ALMA, astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us. Never before had we detected a galaxy’s magnetic field this far away. This video summarises the discovery.
