Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

Sagittarius A* has been seen by human eyes with an "image produced by a global research team called the Event Horizon ...

making it twice as long as the width of the Milky Way. Even more surprisingly, the black hole that powers the quasar from which this jet erupts, designated J1601+3102, is relatively small.

As far as supermassive black holes go, the one at the center of the Milky Way is relatively sedate. But, even in its supposed quiescent state, Sagittarius A* is prone to the occasional belch or ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

Sagittarius A* is the supermassive black hole at the center of the Milky Way. As supermassive black holes go, it is fairly quiet. It’s not creating any galaxy-wide tantrums that should worry us.

In the heart of our Milky Way galaxy, two gigantic "bubbles" extend roughly 50,000 light-years above and below the galactic ...

The Event Horizon Project on May 12, 2022, released the first image first look at the Milky Way black hole, Sagittarius A*. Researchers on Thursday said they discovered black hole jets from the ...

stretching at least twice the length of the Milky Way galaxy. Scientists added, however, that the black hole fueling the quasar producing the jets is small compared to other black holes ...
