Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* must be the central supermassive black hole of the Milky Way galaxy. [11] The current best estimate of its mass is 4.297 ± 0.012 million solar masses .

4 days ago · The supermassive black hole at the center of the Milky Way appears to be having a party, complete with a disco ball-style light show. Using NASA’s James Webb Space Telescope, a team of astrophysicists has gained the longest, most detailed glimpse yet of the “void” that lurks in the middle of our galaxy.

3 days ago · An artist’s illustration depicts the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*. It’s surrounded by a swirling accretion disk of hot gas and dust.

1 day ago · The telescope’s Near-Infrared Camera tracked the black hole for a total of 48 hours over the course of a year, observing five to six large flares per day with smaller sub-flares in between.

5 days ago · Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way. They found the ...

4 days ago · Yusef-Zadeh and colleagues had expected to see flares, but the Milky Way's central black hole, which has a mass of around 4.3 million suns, was more active than predicted, launching cosmic ...

Mar 27, 2024 · What we’re seeing now is that there are strong, twisted and organized magnetic fields near the black hole at the center of the Milky Way galaxy.

Aug 29, 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.

Oct 9, 2024 · Stellar-mass black holes are found throughout our Milky Way galaxy and have masses less than about 100 times that of our Sun. They comprise one of the possible endpoints of the lives of high-mass stars.

May 12, 2022 · First image of the black hole at the centre of the Milky Way. This is the first image of Sagittarius A* (or Sgr A* for short), the supermassive black hole at the centre of our galaxy. It’s the first direct visual evidence of the presence of this black hole.
