A team of astronomers has managed to calculate the speed of a distant supermassive black hole’s spin thanks to the object’s chance meeting with a star—which it promptly destroyed.
A new image of our galaxy’s central black hole reveals the magnetic field surrounding the object in polarized light. The image reveals how gas and superheated matter in the immediate vicinity of the black hole move around it. But aside from that, it’s a great way to visualize the extreme physics happening at the…
