This is the first image ever of a black hole. The breakthrough discovery by the Event Horizon Telescope is an image of the supermassive black hole at the center of Messier 87 (M87) in the Virgo galaxy cluster, 55 million light-years away.
The Event Horizon Telescope, a network of eight telescopes spanning the globe, is an international collaboration led by our astrophysicist Sheperd Doeleman of the Center for Astrophysics | Harvard & Smithsonian.
Black holes are extremely compressed, with enormous masses in a tiny region. (This black hole has 6.5 billion times the mass of our Sun.) Its boundary is the event horizon, beyond which nothing—not even light—can escape from the powerful gravitational pull.
Seeing a black hole allows us to test Albert Einstein’s theory of General Relativity under extreme conditions in the universe. It predicts a black hole will cast a circular shadow, caused by the gravitational bending and capture of light by the event horizon. That's what this image of M87 reveals. 📸: Event Horizon Telescope Collaboration

denisecoates3 Please mention the 29 year old woman involved in making this photo. Don't just praise the men. Thank you.

iamrezaghajar Amazing and sad for people around the world killing each other for name of religious and money

jhwilliams1 What generates the light? Other solar masses? I know so little. This is an amazing image.

deborahstone7181 Now, we can say black holes are a fact. Who knows - maybe we will time travel one day.

kskipperfoster How does the algorithm written by Dr. Katie Bouman fit into this story?

flyingkiwichick I knew Lord of the Rings was real. #suaron #lordoftherings
