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.
[27] [28] The Aerobee rocket launched from White Sands Missile Range on 7 July 1967 yielded further evidence that the source of Virgo X-1 was the radio galaxy M87. [29] Subsequent X-ray observations by the HEAO 1 and Einstein Observatory showed a complex source that included the active galactic nucleus of M87. [30] However, there is little ...
Sagittarius A*: 4.3 × 10 6 [111] (8.54 × 10 36 kg) The black hole at the center of the Milky Way; second black hole directly imaged (after Messier 87) Messier 32: 1.5 × 10 6 – 5 × 10 6 [112] A dwarf satellite galaxy of the Andromeda Galaxy. NGC 4395: 3.599 × 10 5 [113] May be the smallest supermassive black hole.
On January 5, 2015, NASA reported observing an X-ray flare 400 times brighter than usual, a record-breaker, from Sagittarius A*. The unusual event may have been caused by the breaking apart of an asteroid falling into the black hole or by the entanglement of magnetic field lines within gas flowing into Sagittarius A*, according to astronomers.

The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
Sagittarius and Aquarius bring the brains to work. Together, they create a dynamic and intellectually charged team. They love to work independently but can come together to innovate. Aquarius ...
A Sagittarius-Sagittarius friendship is full of fun. These two love to party and share adventures. This duo will thrive in social settings so make sure to invite them to the party — any party.
The Sagittarius A* cluster is the cluster of stars in close orbit around Sagittarius A*, the supermassive black hole at the center of the Milky Way (in the Galactic Center). The individual stars are often listed as " S-stars ", but their names and IDs are not formalized, and stars can have different numbers in different catalogues .
