In this artist's impression we see the planet HIP 67522 b sending a wave of energy down the magnetic field lines towards the surface of its host star. Where the wave meets the end of the magnetic field line at the star's surface, it triggers a massive flare. Credit: Danielle Futselaar (www.artsource.nl/)

The Weirdest Thing I Learned This Week

Plus other weird things we learned this week.

This image, taken with ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5. These are the expanding remains of a star that exploded hundreds of years ago in a double-detonation – the first photographic evidence that stars can die with two blasts. The data were captured with the Multi-Unit Spectroscopic Explorer (MUSE) instrument at the VLT. MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two layers indicate that the now-dead star exploded with a double-detonation.
