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.

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 colossal black hole lurking at the center of the Milky Way galaxy is spinning almost as fast as its maximum rotation rate.

What the researchers discovered is that the Milky Way’s supermassive black hole is spinning somewhere between .84 and .96, close to the top limit that our current model of black holes allows for.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding supermassive black hole.

By ADITHI RAMAKRISHNAN. NEW YORK (AP) — Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center of our Milky Way galaxy ...

D9 is the first star pair ever found near Sagittarius A*, the supermassive black hole at the centre of the Milky Way. This image shows an emission line of hydrogen mapped by the SINFONI instrument ...
