The Galactic Center (or Galactic Centre) is the rotational center, the barycenter, of the Milky Way galaxy. Its central massive object is a supermassive black hole of about 4 million solar masses, which powers Sagittarius A*, a compact radio source which is almost exactly at the galactic rotational center.The Galactic Center (or Galactic Centre) is the rotational center, the barycenter, of the Milky Way galaxy.

Is the middle of the Milky Way a black hole?
The supermassive black hole at the center of our Milky Way galaxy is leaking. The Milky Way's central black hole, known as Sagittarius A* (Sgr A*), has been "leaking" or emitting jet-like superheated beams for several thousand years.
What is in the center of the Milky Way?
At the center of the Milky Way sits a supermassive black hole called Sagittarius A*. With a mass equal to that of four million suns, the black hole, discovered in 1974, can be observed in the sky with radio telescopes close to the constellation Sagittarius.
How many black holes are in the center of the Milky Way?
Most galaxies, and maybe all of them, harbor such a black hole. So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides in the center of our Milky Way galaxy, 28 thousand lightyears away.
Is our universe in a black hole?
Our universe may reside within a vast, black hole. Let's rewind the clock. Before humans existed, before Earth formed, before the sun ignited, before galaxies arose, before light could even shine, there was the Big Bang. This happened 13.8 billion years ago.
Does every galaxy have a black hole?
Spectacular jets are powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A. The jets shoot through space for millions of trillions of miles.
Do all galaxies have a black hole in the center?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way.
What is the closest black hole to Earth?
In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just 1,000 light-years away, only to have other scientists dispute the findings.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Is there a white hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
