The star passes very close to the Milky Way’s supermassive black hole and could reveal the black hole’s spin by tracking how ...

A star called S301 passes Sagittarius A* at 8% of light speed, near enough that the black hole's spin should bend its orbit.

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to ...

A telescope has spied the fastest known star in our galaxy, racing around the supermassive black hole at the center of the Milky Way.

Sgr A* is the name we’ve given to the supermassive black hole that sits at the center of the Milky Way. We’ve known about its presence since the 1970s but only managed to image it within the past few ...

The newfound star S301 orbits the Milky Way’s supermassive black hole so closely that its view of the heavens gets twisted ...

If this star was almost anywhere else in the universe, it would be downright mundane. S301, you see, orbits Sagittarius A* (Sgr A*), the supermassive black hole that inhabits the exact geometric ...

Active black holes are easy to detect. Their superheated accretion disks emit bright X-rays, and the jets streaming from ...

Astronomers have discovered the fastest star in the Milky Way zooming at 25,000 kilometres a second around the supermassive black hole at the centre of our galaxy.

Astronomers using the W.M. Keck Observatory and Gemini North Telescope on Mauna Kea have published a study about Wolf-Rayet ...
