Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. The formation of such a large black hole and how it affects the evolution of its host galaxy are not well
Called Sagittarius A*, the object has captured astronomers' curiosity for decades. Scientists verified the existence of Astronomers spot ancient effects from a supermassive black hole's jets.
In the case of Sgr A*, there is a mysterious absence of the high energy emission (X-rays and UV radiation) often observed from active galactic nuclei. The signal from this galactic giant repeated every hour and this behavior was seen in several snapshots taken before satellite observations were blocked by our Sun in 2011. Recent observations of nearby galaxies reveal that such supermassive black holes are not unique to the MIlky Way. Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Astronomers have found six strange objects orbiting the Sagittarius A* supermassive black hole at the center of the Milky Way, which are unlike anything else in the galaxy. By Meghan Bartels 31 March 2020. Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory.

They are so strange, in fact, that scientists have had to create a new class of celestial object for them, called ‘G objects.’ Observations made with ESO’s Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein’s general theory of relativity. I would suggest the episodes about supermassive At the center of our galaxy is a supermassive black hole in the region known as Sagittarius A.
While the presence of a supermassive black hole at the center of our Galaxy has long been suspected, and while the available dynamical evidence has long been consistent with that suspicion, the data have only recently become unambiguous and compelling that alternative hypotheses are not feasible. Researchers discovered a relation between the mass of all the black holes and the center of their galaxies known as the bulge.
It all went down 11 billion light-years away. Rendering of a star called S0-2 orbiting the supermassive black hole at the center of the Milky Way. Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Astronomers have found convincing evidence for a supermassive black hole in the center of our own Milky Way galaxy, the galaxy NGC 4258, the giant elliptical galaxy M87, and several others.
