Our Black Hole Daddy: Sagittarius A* in Milkyway – Space Engine – Beauty Above Us


Just like Earth, and other objects of our
Solar System orbits around the Sun, the sun also orbits around a massive object which
is situated at the center of our Milky Way galaxy. This massive object is a supermassive black
hole, located inside Sagittarius A region. Astronomers haven’t actually seen the supermassive
black hole itself. Instead, they have observed the motion of
stars in the vicinity of Sagittarius A*. After 10 years of observations, astronomers
detected the motion of a star that came within 17 light-hours distance from the supermassive
black hole; that’s only 3 times the distance from the Sun to Pluto. Only a compact object with the mass of millions
of stars would be able to make a high mass object like a star move in that trajectory.
