A supermassive black hole has been caught in the act of fleeing its home galaxy, racing through intergalactic space at ...

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 ...

A black hole the mass of at least ten million suns is tearing through space, fast enough to escape its home galaxy. As it ...

The James Webb Space Telescope has just confirmed a cosmic fugitive: the first known supermassive black hole racing through ...

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 ...

This illustration shows a star exploding as a supernova and subjecting its binary companion to the explosion’s brute force. If conditions are right, the binary companion can be ejected from the galaxy ...

The most massive black hole ever measured may be an intergalactic hitchhiker that escaped from one galaxy before getting captured by another. If this scenario, laid out in a paper posted February 18 ...

A mysterious black hole—that has yet to be discovered—in one of our galaxy's spiral arms appears to have hurled a star across the Milky Way, an international team of astronomers has said. The ...

Hot blue stars kicked out of their cradles may explain a mysterious ultraviolet glow that surrounds the disks of many spiral galaxies. A new computer simulation demonstrates that these runaway stars ...

In 1988, the astrophysicist Jack Hills at Los Alamos National Laboratories wondered what might happen if a binary star system were to wander too close to the supermassive black hole at the centre of ...

An artist's impression of S5-HVS1's ejection by Sagittarius A*, the black hole at the center of the galaxy. The black hole and the captured binary partner to S5-HVS1 are seen far away in the left ...
