    A black hole is an object so compact (usually a collapsed star) that nothing can escape its gravitational pull. Not even light. The escape velocity of a black hole exceeds the speed of light. Since nothing can travel faster than this ultimate speed, black holes suck in everything including light, which makes them utterly dark and invisible. In this image, we can see a black hole, but only because

Its mass dominates the total mass of the galaxy system.

The eclipse in this image affords us a similar view of the corona of the extrasolar planet's star. It also allows us to see detail on the surface of the planet, which is highly volcanic.
