Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The ...

Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the ...

The James Webb Space Telescope has just confirmed a cosmic fugitive: the first known supermassive black hole racing through intergalactic space at roughly 2.2 million miles per hour, fast enough to ...

Most stars in the Milky Way have humdrum lives, tracing slow predictable orbits around the galactic center. But a few have a different destiny. Instead of orbiting, the hypervelocity stars are leaving ...
