At the core of the galaxy, about 26,000 light-years away in space, is Sagittarius A*, a supermassive black hole about 4 ...

Observations from the Event Horizon Telescope may reveal a secret merger in our supermassive black hole's past, potentially explaining the cosmic monster's unusual spin.

— New view of the supermassive black hole at the heart of the Milky Way hints at an exciting hidden feature (image) — In the last 25 years, black hole physicists have uncovered the unimaginable ...

The supermassive black hole at the center of our Milky Way galaxy is leaking. The Milky Way's central black hole, known as Sagittarius A* (Sgr A*), has been "leaking" or emitting jet-like ...

The black hole known as Sagittarius A* (Sgr A*) is situated in the middle of the Milky Way, just 26,000 light years from Earth, according to NASA.

The Milky Way 's supermassive black hole, known as Sagittarius A* (Sgr A*), is over 4 million times more massive than our sun.

At 4 million times the mass of the Sun, the black hole at the center of the Milky Way Galaxy is rather humdrum, as far as supermassive black holes go. But a new analysis reveals that it’s a lot ...

Astronomers already knew that the Milky Way hosts a central black hole, weighing some four million suns. From Earth, this black hole is a dense, tiny thing in the constellation Sagittarius, only ...

A black hole (one illustrated) with a mass equal to about 68 suns has been found in the Milky Way, researchers say. That dark mass is much heavier than other similar black holes.

But the Milky Way’s black hole, Sagittarius A*, is actually much smaller than the first and was more difficult to see, since it required peering through the hazy disk of our galaxy.

In a first, astronomers think they’ve used those telltale signals to identify the closest, lightest-mass black hole in the entire Milky Way, so far. Here’s the story of this cosmic unicorn.

This illustration shows the Milky Way’s central, 4-million-solar-mass black hole, along with the structures around it, such as a swirling disk of gas and dust and a possible radio-emitting jet.
