Black holes were discovered in 1972 by Tom Bolton.
When Tom Bolton discovered this, the black hole was 8,200 light years away from the Earth (1 light year is 6 trillion miles).
Black Holes are being found all the time. There are a great many of them out there.
They were discovered when large amounts of high-energy X-Rays and gamma rays emmitted from apparently empty space. As well as this, they observed stars quickly orbitting apparently nothing.
1916, Albert Einstein came up with the theory about Black Hole.
Your use of "the" black hole seems to indicate that you are thinking about one specific black hole. Please clarify which one - there are several known black holes, discovered at different times.
The concept of a black hole was first discovered mathematically in 1916 through the equations of Einstein's general relativity. Using mathematics scientists were able to figure out many of the properties and behaviors of black holes before the end of the 1960s. The first direct psychical evidence of a black hole was not found until the late 1970s.
He discovered that black holes give off radiation.
Roy Kerr, a mathematician from New Zealand, discovered the solution to the equations of general relativity that describes a rotating black hole.
Karl Schwarzschild discovered black holes.
Holes, which include black holes and ozone holes were discovered in the space and atmosphere respectively.The black hole was discovered in the space and ozone holes were discovered above the Antarctica.
Astronauts didn't discover black holes....
The guy that discovered black holes.
Yes. Several quasars have been discovered; they are black holes, and they are quite active.
He did not. He made some theoretical discoveries about how black holes would probably behave; but the concept of black holes was discovered by others before him.
1916, Albert Einstein came up with the theory about Black Hole.
The discovery of black holes was not due to a single person; several people participated, and at first, it was all very theoretical. You can find some of the history behind the theories and discoveries in the Wikipedia article on "Black hole".

There have been a few prominent Indian cosmologists who have worked on black holes but you are probably thinking of Jayant Narlkiar.
