A black hole can be defined as a region in the galaxy where the gravitational pull is so intense such that no object can escape including light. Any matter near it is squeezed and compressed to occupy the smallest space possible. By pulling light to it, the black hole is invisible from the Earth. Some black holes were formed when the universe was created whereas others are created when a star collapses. Black holes differ in sizes with some being small and others massive. In this article, we look at the supermassive black holes (SMBH). The unit of measuring the black holes is in solar masses or in comparison to the mass of the Sun in the solar system.
The Monster black hole is the biggest in the universe. The hole is located at a distance of 250 million light-years away. It is in the galaxy NGC 1277 and is the largest component in the host galaxy. The black hole was by Remco van den Bosch a senior Germany astronomer. This gigantic hole is so huge such that if measured against planet Neptune’s orbit, it is eleven times wider and the mass is the size of seventeen billion Suns combined together. The hole also referred to as the supermassive black hole occupies a total more than 14 percent of the mass of the galaxy where it is located.
Other Massive Black Holes
Ton 618 is also one of the biggest black holes. It is estimated to have a mass of six hundred and sixty times the size of the Sun. It is closely followed by the S5 0014+82. This hole measures four hundred times the mass of the Sun. The fourth largest hole is called the SDSS ji12325.31+514252.0. The hole is estimated to measures three hundred and thirty-one times the mass of the Sun. This mass is as result of quasar Mgll emission and scientists believe it is rapidly increasing due to its high gravitational pull. The Central hole of H1821=643 follows in size at an estimated 300 times the size of the Sun. Astronomers estimate that it also hosts a quasar in its center making the singularity highly dense.
The Fastest Increasing Black Holes
A black hole discovered at the center of the elliptical region of the Phoenix area measures two hundred times the mass of the Sun. This peculiar black hole increases at an estimated rate of 60 meters per annum making it the fastest increasing hole. SDSS J074521.78+7343361 follows in size at 195 times the mass of the Sun. Others are the OJ 287 primary and the Abell 1201 BCG at 130 times larger than the Sun.
Discovering More Black Holes
Astronomers at the Hubble Space Telescope are still sending more sophisticated and advanced satellites to the space and use an array of telescopes to in an effort to discover more black holes. There could be other bigger black holes that will be unearthed since it is believed that there are more than one hundred million black holes. The latest news from NASA dated October 2017 stated that the telescopes have spotted pairs of five big black holes in the space. The astronomers are yet to uncover their identity and size.
