Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way. Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius , about 5.6° south of the ecliptic , [ 7 ] visually close to the ...
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.
The black hole, known as Sagittarius A*, appears as a faint silhouette amidst the glowing material that surrounds it. The image reveals the turbulent, twisting region immediately surrounding...
Sagittarius A*, often abbreviated to Sgr A* and pronounced "Sagittarius A star", is a supermassive black hole located at the center of our spiral galaxy, the Milky Way.
Sagittarius A*, supermassive black hole at the center of the Milky Way Galaxy, located in the constellation Sagittarius and having a mass equivalent to four million Suns. The event horizon of the black hole has a radius of 12 million kilometers (seven million miles).
The distance from the center of Sagittarius A* to its event horizon, a measurement known as the Schwarzschild radius, is enormous at seven million miles (12,000,000 kilometers or 0.08 astronomical units). But its apparent size when viewed from Earth is tiny because it is so far away. The apparent Schwarzschild radius for Sagittarius A* is 10 ...
The new image of Sgr A* follows the first-ever image of a black hole, which was obtained by the EHT in 2019. That groundbreaking image was of M87*, the supermassive black hole at the center of Messier 87, a galaxy located 53 million light years from Earth.
The historic image of Sagittarius A* is the culmination of a decades-long astronomical quest—and a crucial step toward a new understanding of black holes, gravity and spacetime
Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, woke some 200 years ago to devour cosmic debris, according to new findings from NASA’s Imaging X-ray Polarimetry Explorer.
Nature - The Event Horizon Telescope network has captured the second-ever direct image of a black hole — called Sagittarius A* — at the centre of the Milky Way.
