What are supermassive black holes?
Supermasive black holes are gravitational features located in the middle of many galaxies, including the Milky Way. Supermasive black holes can be thought of galactic sun: in the same way as planets on the solar system orbits in the Sun, 200–400 billion solar systems on the mammary path in orbit. Superma -mass black holes contain 10

(hundreds of thousands and tens of billions) solar materials.SuperMassive Black Hole Our Galaxy is suspected of a compact object called Sagittarius and*, which contains 3.7 million solar masses in volume with a radius not more than 6.25 light hours (45 AU) or about 4.2 billion miles. They will join and create one object in less than 100 years. Sometime around 2015–2025, the technology of the astronomical interferomet enables to directly display the horizon of the event Sagittarius and*.
In very distant galaxies, astronomers observe the process of birth of supermassive black holes. These galaxies are called active galaxies and can release energy equivalent to hundreds of average galaxies together, with the clarity of one trillion the sun. Quales are a type of active galaxy and is one of the most distant objects that astronomers can detect. Others are crazy, which is one of the most annoying phenomena in space, converting 100 suns into a relativistic beam of radiation every year.
At least 30 suspicious supermassive black holes were observed in other galaxies except for the Milky Way. Supermasive black holes are part of an unresolved problem in astrophysics: where are the black holes an intermediate? Numerous stella-black holes R-Mass are known, with materials ranging from 1.44 solar materials up to 14 sun masses. They are created when the cores of massive stars can no longer support their own weight and create gravitational singularity.There are several candidate phenomena for medium black holes, but none is definitive from this point.
