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.

Because the Milky Way is disk-shaped, astronomers had to look through clouds of dust and debris to peer at the dense heart of our galaxy where the supermassive black hole was thought to lie.

For the first time, astronomers have captured an image of the supermassive black hole at the center of our Milky Way galaxy, confirming the presence of the cosmic object. It is 4 million times ...

For years, the supermassive black hole in the dark center of the Milky Way galaxy has been theorized about and studied — and finally, it's been captured in an image.

Its Milky Way home, a spiral galaxy, is fairly flat, but the center sinks down where the supermassive black hole sits. All around it are stars zipping in varied directions.

Is the Milky Way's supermassive black hole launching a hidden jet? The polarization of light and neat and strong magnetic fields of Sgr A*, and the fact that they closely resemble that of M87*, ...

For example, astronomers have observed unusual motions of stars and unexplained mass distributions within it, which could be the result of the gravitational pull of a central black hole. In other ...

The black hole at the center of the Milky Way is referred to as Sagittarius A*, or Sgr A*, which is pronounced “sadge-ay-star.” It is more than a thousand times smaller than the black hole in ...

The Milky Way's supermassive black hole, known as Sagittarius A* (Sgr A*), is over 4 million times more massive than our sun. Its strong gravitational pull draws nearby stars and gas clouds into ...

Astronomers still do not understand how these supermassive black holes have grown so big. ... The Milky Way’s black hole is a “gentle giant” compared to the one in M87, ...
