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 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.
The Webb observations mark the longest, most detailed look researchers have been able to make around the Milky Way’s central black hole, called Sagittarius A*, building on past evidence of its ...
To conduct this study, the team used the telescope’s infrared imaging capabilities, observing Sagittarius A* for 48 hours during the course of a year and tracking the black hole’s changes.
Supermassive black hole Sagittarius A* imaged by the Event Horizon Telescope in radio waves. The central dark spot is the black hole's shadow, which is larger than the event horizon . Bright X-ray flares from Sagittarius A* (inset) in the center of the Milky Way, as detected by the Chandra X-ray Observatory .
In this image of M87* taken on 11 April 2017 (a representative example of the images collected in a global 2017 EHT campaign), the shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape.

A view of M87* black hole in polarised light Sagittarius A*, black hole in the center of the Milky Way. The Event Horizon Telescope (EHT) is an active program that directly observes the immediate environment of black holes' event horizons, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observing the black hole ...
