AZUZ: Researchers with the National Science Foundation, a U.S. government agency, say a super massive black hole is more than a Muse song. They say they captured a picture of one and that this is the first direct visual evidence that black holes exist. Some physicists have argued that they don't.
In theory, a black hole is a body whose gravity is so intense that not even a light can escape from it. To capture what they say is an image of one, scientists synced up a global network of telescopes in 2017, and they all zoomed in on a spot in the universe that's estimated to be 55 million light years away from earth.

It took two years for them to combine the data and produce this picture. What they called an M87 black hole is the shadow in the middle and they say the orange glow around it is the material that's creating the event horizon.
The director of the National Science Foundation says pictures like this help scientists understand the mysteries of black holes and reveal the complexities of the universe. Their investigation of M87 continues.
