The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

Supermassive black hole mergers occur when entire galaxies merge together. Bumps and kinks in the Milky Way's disk indicate it likely collided with at least a dozen galaxies during the past 12 ...

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 ...

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

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.

An illustration comparing the Milky Way with 2MASX J23453268−0449256. Bagchi and Ray et al. / Hubble Space Telescope. The extreme black hole is not the only unusual feature of 2MASX J23453268− ...

We know black hole mergers occur because we can detect the resulting gravitational waves. But when trying to piece together ...

Two stars may be orbiting each other near a supermassive black hole in our Milky Way galaxy The celestial sighting is interesting and unusual, and more research is needed to be certain of what the ...

Astronomers have detected a mid-infrared flare from the supermassive black hole at the heart of the Milky Way galaxy for the very first time, and it’s shedding new light on the complex physics ...

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 ...

Supermassive black hole mergers occur when entire galaxies merge together. Bumps and kinks in the Milky Way's disk indicate it likely collided with at least a dozen galaxies during the past 12 ...

NEW YORK — 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. Nearly every large galaxy has a ...
