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 Butterfly Cluster (M6) and Lambda Scorpii.
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.
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [11] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [12] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.
NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the center of our Milky Way galaxy, observing a steady ...
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope. [32] The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.
At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. But since NASA's James Webb Space Telescope came online in ...
At the center of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that some scientists have called a gentle giant because of its ...
Below: supermassive black hole devouring a star in galaxy RX J1242−11 – X-ray (left) and optical (right). [98] Unambiguous dynamical evidence for supermassive black holes exists only for a handful of galaxies; [99] these include the Milky Way, the Local Group galaxies M31 and M32, and a few galaxies beyond the Local Group, such as NGC 4395.
