Astronomers Discovered Thousands of Black Holes at the Center of Milky Way

Astronomers announced the discovery of thousands of black holes last months, at the center of the Milky Way. The data was provided by NASA’s Chandra X-ray Observatory. “This black hole bounty consists of stellar-mass black holes” which are estimated to be five to 30 times the mass of our Sun. These new black holes were discovered within three light years of the supermassive black hole at our Galaxy’s center, called Sagittarius A*.

A Star Passes Black Hole: At last Scientists Have Chance Testing Einstein’s Theory of General Relativity

Scientist were waiting to this special moment about many years. Continuously for several months astronomers are planning to focus on their telescopes to Sagittarius A*, the Supermassive black hole at the center of our galaxy. A Star is cycling by closely orbiting star, which is probably considering that it is testing Einstein’s theory of general relativity. S-02 Star, which is the name of this star, closely orbits Sagittarius A*. However, S-02 is unique because it is one of the two stars that zoom in the closest to the supermassive black hole in its elliptical orbit, that is to say it is likely to show the effects and results of black hole’s enormous gravitational pull.

The Biggest Black Holes are Outgrowing Their Galaxies

The biggest black holes are growing faster than the rate of stars being formed in their galaxies, in accordance with two new studies using data from NASA’s Chandra X-ray Observatory and other telescopes. More than many years, astronomers have collected data on the arrangement of stars in galaxies and the growth of the biggest black holes (that is, those with millions or billions the mass of the Sun) in their centers.

Scientists Discovered Black Hole 12 Billion Times Larger than The Sun

Scientists from Peking University in China and from the University of Arizona announced their findings the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The discovery of this quasar, named SDSS J0100+2802, marks an important step in understanding how quasars have evolved from the earliest epoch 900 million years after the Big Bang, thought to have happened 13.7 billion years ago. The quasar, with its central black hole mass of 12 billion solar masses and the luminosity of 420 trillion suns, is at a distance of 12.8 billion light-years from Earth.

Birth of the Black Holes

Black holes are celestial objects which are so dense, that not even light can escape they intense gravitational pull. Their gravity is not sufficient to overpower the atomic and nuclear forces of their interiors, which resist compression. But in more massive objects, gravity ultimately wins. This phenomenon occurs when a dying stars runs out of fuel and collapses under the weight of their own gravity. According to scientists, there might be three types of black holes : stellar, supermassive, and miniature black holes – depending on their mass. Astronomers can measure the mass of black holes by studying the material that orbits around them.
