I really don't understand this at all, a black hole emits nothing, the only thing we can actually "see" is light, so how can you have a photograph of a black hole? Never mind the fact that this one is supposed to be 55 million light years away, imagine the distortions this image (without light) must have had in that time. By the way the people who did this say it isn't actually a picture of a black hole more like of its shadow.
