In November 2004, a team of astronomers reported the discovery of a potential intermediate-mass black hole, referred to as GCIRS 13E, orbiting 3 light-years from Sagittarius A*. This black hole of 1,300 solar masses is within a cluster of seven stars.
29 Αυγ 2013 · The center of the Milky Way galaxy, with the supermassive black hole Sagittarius A* (Sgr A*), located in the middle, is revealed in these images. As described in our press release, astronomers have used NASA’s Chandra X-ray Observatory to take a major step in understanding why material around Sgr A* is extraordinarily faint in X-rays.
Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
12 Μαΐ 2022 · Learn about the size, mass, distance and observation of Sagittarius A*, a dormant cosmic titan at the center of our galaxy. See the first image of the black hole captured by the Event Horizon Telescope in 2022.
12 Μαΐ 2022 · These speedy stars also serve to clearly demonstrate that Sagittarius A* is indeed a black hole, as other arrangements like a dense clump of dead stars would result in different orbits.
9 Οκτ 2024 · Narrated by Caltech’s Katie Bouman, this video explains how she and her fellow teammates at the Event Horizon Telescope project managed to take a picture of Sagittarius A* (Sgr A*), a beastly black hole lying 27,000 light-years away at the heart of our Milky Way galaxy.

12 Μαΐ 2022 · The Event Horizon Telescope captures the light around the supermassive black hole at the center of the Milky Way galaxy, revealing a glowing, donut-shaped ring. The image confirms Einstein's theory of general relativity and the similarity of all black holes.
