English: Artist's concept of what a future telescope might see in looking at the black hole at the heart of the galaxy M87. Clumpy gas swirls around the black hole in an accretion disk, feeding the central beast. The black area at center is the black hole itself, defined by the event horizon, beyond which nothing can escape. The bright blue jet shooting from the region of the black hole is created by gas that never made it into the hole itself but was instead funneled into a very energetic jet.
