Answer: Black Holes

In 1974, renowned physicist Stephen Hawking proposed a theoretical argument for the existence of a very unique type of black-body radiation emitted by black holes, which can only exist because of quantum effects that occur near the event horizon. The radiation was named Hawking radiation in honor of Hawking’s theoretical work that provided the framework for further study of it.

In June of 2008, NASA launched the Fermi Gamma-ray Space Telescope which, among other tasks, is searching for Hawking radiation and other traces of black holes.
