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.
Sagittarius A* was discovered and named on February 13 and 15, 1974, by astronomers Bruce Balick and Robert Brown using the Green Bank Interferometer of the National Radio Astronomy Observatory. [34] They discovered a radio source that emits synchrotron radiation; it was found to be dense and immobile because of its gravitation. This was ...
One of the most studied stars is S2, a relatively bright star that also passes close by Sgr A*. As of 2020 [update] , S4714 is the current record holder of closest approach to Sagittarius A*, at about 12.6 astronomical units (1.88 × 10 9 km), almost as close as Saturn gets to the Sun, traveling at about 8% of the speed of light.
LID-568 has a mass about 10 million times greater than the sun, so 2-1/2 times that of Sagittarius A*. The researchers have not yet determined the mass of its home galaxy.
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which is almost exactly at the galactic rotational center.
Sagittarius’ sun sign is Sagittarius, but you knew that already. As a fire sign, Sagittarius is all about energy, action and motivation . They are often quick to get inspired and make for highly ...

As of 21 May 2015, WISE-J224607.57-052635.0-20150521 is the most luminous galaxy discovered and releases 10,000 times more energy than the Milky Way galaxy, although smaller. Nearly 100 percent of the light escaping from this dusty galaxy is Infrared radiation.
