This artist’s impression shows the magnetic white dwarf WD 0816-310, where astronomers have found a scar imprinted on its surface as a result of having ingested planetary debris. When objects like planets or asteroids approach the white dwarf they get disrupted, forming a debris disc around the dead star. Some of this material can be devoured by the dwarf, leaving traces of certain chemical elements on its surface. Using ESO’s Very Large Telescope, astronomers including UCL researchers found that the signature of these chemical elements changed periodically as the star rotated, as did the magnetic field. This indicates that the magnetic fields funnelled these elements onto the star, concentrating them at the magnetic poles and forming the scar seen here. Credit: ESO/L. Calçada

EHT researchers created around 1.8 million computer models simulating Sagittarius A* and narrowed them down to a handful of best fit models, the best of which is shown in this video. This is what radio telescopes might observe if they had infinite resolution. Credit: Ziri Younsi, Christian M. Fromm, Yosuke Mizuno & Luciano Rezzolla

The first image of the supermassive black hole at the centre of our galaxy has been unveiled by the Event Horizon Telescope Collaboration involving Dr Ziri Younsi (UCL Mullard Space Science Laboratory). Dr Younsi explains the significance of the discovery and why it took five years for the global research team to extract the image from observational data obtained in 2017. Credit: UCL / FILMBRIGHT

Credit: Ryuichi Kanai. Caption: Initial tsunami waves are typically a few centimetres high but nonetheless cause a disturbance in the Earth’s upper atmosphere by pushing up air and creating an acoustic wave that is amplified as it goes higher. This leads to a change in the ionosphere, 300km above the surface of the Earth, in which the density of electrons in the area is reduced.

Jupiter’s mysterious X-ray auroras have been explained, ending a 40-year quest for an answer. For the first time, astronomers have seen the way Jupiter’s magnetic field is compressed, which heats the particles and directs them along the magnetic field lines down into the atmosphere of Jupiter, sparking the X-ray aurora. The connection was made by combining in-situ data from NASA’s Juno mission with X-ray observations from ESA’s XMM-Newton. Credit: ESA/NASA/Yao/Dunn
