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. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. Called Sagittarius A*, the object has captured astronomers' curiosity for decades.

As stated previously, these black holes exist at the center of every galaxy including the Milky Way, but it was recently discovered that the size of the supermassive black hole’s mass has a direct correlation with the size of its host galaxy’s mass.

Scientists verified the existence of 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. The formation of such a large black hole and how it affects the evolution of its host galaxy are not well Researchers discovered a relation between the mass of all the black holes and the center of their galaxies known as the bulge. 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. Shares. ; IR: NASA/STScI

They are so strange, in fact, that scientists have had to create a new class of celestial object for them, called ‘G objects.’ Like most galaxies, the Milky Way hosts a supermassive black hole at its center.

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.

The black hole’s heartbeat was first detected in 2007 at the center of a galaxy called RE J1034+396 which is approximately 600 million light-years from Earth. Rendering of a star called S0-2 orbiting the supermassive black hole at the center of the Milky Way.

An image of the area surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, in X-ray and infrared light. By Meghan Bartels 31 March 2020. The formation of such a large black hole and how it affects the evolution of its host galaxy are not well understood. 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. I would suggest, if you are really interested, for you (or anyone) to go to the “Science Channel” with the series “How the Universe Works” and watch the episodes that interest you. They are so strange, in fact, that scientists have had to create a new class of celestial object for them, called ‘G objects.’ Called Sagittarius A*, the object has captured astronomers' curiosity for decades.
