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.
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [8] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [9] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.
The supermassive black hole Sagittarius A*, ... the radius of Earth's orbit around the Sun is about 150 million kilometers ... (1,000 light years) across and 4.2 ...
The famous first picture of the supermassive black hole at the heart of our galaxy might not be accurate, a new study has claimed. The picture – initially published in 2022, after years of ...
A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Black holes are extraordinarily dense objects with gravity so strong that not even light can escape.
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 ...
As of February 2022, only one isolated black hole has been confirmed, OGLE-2011-BLG-0462, around 5,200 light-years away. [2] The nearest known black hole is Gaia BH1, which was discovered in September 2022 by a team led by Kareem El-Badry. Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus. [3]
The first image of the black hole at the center of the Milky Way galaxy, named Sagittarius A*, has been captured by NASA's Event Horizon Telescope.
