Black Hole?


You’re looking at the “model” layer – if you flip back to the “image” layer,
you’ll see that this is a giant bright star, so bright that you’d be able to see with your own unaided eyes. Super bright stars cause a bunch of problems for our image processing, so things are often a bit messed up in those areas!


Black holes themselves are fundamentally unseeable. There’s no way to bring back light from beyond the event horizon—the point at which light itself is irrecoverably lost to the object’s gravity. The only way we know of their existence is to observe their effects on light and other objects. Supermassive black holes are usually smaller than a pixel in distant galaxies because the whole galaxy is a million times larger than the black hole itself. We can also detect black holes by detecting the ripples in space-time created when two of them crash into each other. From that signal, we can tell how massive the black holes were, how far away they were, and how fast they were traveling when they collided.
