Black hole astronomy definition

WebDirect evidence for a supermassive black hole – a plot of the orbital motion of the star S2 around the centre of the Milky Way. From these observations, astronomers have inferred that a supermassive black hole of about four million solar masses lurks at the centre of our Galaxy. Credit: ESO A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has a great effect on the fate and circums…

Within the event horizon, the escape speed ( vesc) exceeds the speed of the light ( c) and an object is trapped forever. Outside the event horizon, vesc < c … A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions of times the mass of the Sun (M☉).
