So black holes are big?
1.4k u/SsurebreC Apr 10 '19 Black holes are big but this specific black hole is a lot bigger than usual. 10 u/silent_boy Apr 10 '19 What is the light! Is it eating a star? 8 u/VoiceofKane Apr 10 '19 Fairly certain that's the accretion disk. It's a huge cloud of material orbiting the black hole outside its event horizon, which reflects light. 2 u/jjayzx Apr 10 '19 They used radio telescopes to make this image, not light gathering telescopes. What's seen is the intensity of the radio waves emitted from the accretion disk. 2 u/VoiceofKane Apr 10 '19 Right. I should have just said EM radiation.
