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

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 ...

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 ...

This black hole is estimated to weigh around 600,000 solar masses, significantly smaller than the supermassive black hole at the center of the Milky Way, Sagittarius A*, which weighs about 4.3 ...

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 ...

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− ...

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.

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

What's New. Astronomers have observed a binary star system orbiting near the supermassive black hole at the center of the Milky Way galaxy. The discovery of Sagittarius A* (Sgr A*), published ...

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 ...

At the center of every galaxy is an immense cosmic engine known as a supermassive black hole. In the Milky Way, that engine is known as Sagittarius A* and it’s the ultra-massive object—around ...
