No, we can't detect Hawking radiation, yet. It's too faint. http://physics.stackexchange.com/questions/48032/how-would-you-detect-hawking-radiation http://physi

> Emitted Radiation
When material falls into a black hole from a companion star, it gets heated to millions of degrees Kelvin and accelerated. The superheated materials emit X-rays, which can be detected by X-ray telescopes such as the orbiting Chandra X-ray Observatory.
> In addition to X-rays, black holes can also eject materials at high speeds to form jets. Many galaxies have been observed with such jets. Currently, it is thought that these galaxies have supermassive black holes (billions of solar masses) at their centers that produce the jets as well as strong radio emissions.

- qrendel 11y agoI thought the question was about radiation emitted by the black hole itself, i.e. Hawking radiation, not radiation emitted by matter outside but near the black hole, i.e. accretion disk radiation. It's not really contradictory that stuff outside the event horizon can still escape.
- MichaelApproved 11y agoYou are correct, I was mistaken.
