So ,till 1974 scientist believed that black hole are immortal since they don't emit radiation.But in 1974 a an English theoretical physicist, cosmologist Stephen William Hawking proposed his theory that black holes also emit radiation.
He identity this by combining quantum mechanics and general theory of relativity.
He said that the blank space in our universe are not actually blank but ,collision of virtual matter and its anti matter and they both disappear,.
So ,like other parts of the universe ,at the event horizon there should be virtual masses forming and one goes to the singularity and other pops out from black hole as gamma radiation.so this radiation was termed as hawking radiation,in the honored of his discovery.
f black holes evaporate under Hawking radiation, a solar mass black hole will evaporate over 1064 years.A super massive black hole with a mass of 1011 (100 billion) M☉ will evaporate in around 2×10100 years. Some monster black holes in the universe are predicted to continue to grow up to perhaps 1014 M☉ during the collapse of super clusters of galaxies. Even these would evaporate over a timescale of up to 10106 years.
In June 2008, NASA launched the Fermi space telescope, which is searching for the terminal gamma-ray flashes expected from evaporating primordial black holes. In the event that speculative large extra dimension theories are correct,
At its end time there will be a huge blast of gamma rays takes place.
