The radiation presumed to be given off by a black hole by quantum mechanical processes.
Examples
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how this radiation would be changed with quantum corrections to Einstein's theory of gravity.
Although Hawking radiation is too small to be observed, it remains an important discovery that allows physicists to peer into what unification may look like.
Google for Hawking radiation, black hole evaporation, the wikipedia has a lot of nice, high school-level formulas for it.
If Hawking radiation is proved to be true won't black holes lose entropy which is against laws of thermodynamics?
Stellar-mass or larger black holes receive more mass from the cosmic microwave background than they emit through Hawking radiation and thus will grow instead of shrink.
