Q& A: Black Holes
Is the light of the black hole "images" from your web site X-ray
light from inside the black hole?
No light of any kind, including X-rays, can escape from inside
the event horizon of a black hole. The X-rays Chandra observes
from the vicinity of black holes are from matter that is very
close to the event horizon of black holes. Matter is heated to
millions of degrees as it is pulled toward the black hole, so it
glows in X-rays.
