The EHT picture of the black hole in M87 looks blurry, but the object is VERY far away. Some computation shows that the Airy disk is about 18 micro-arc-seconds. (They claim 20 micro-arc-seconds.) To put that in perspective, here's a picture of Neil Armstrong's Footprint as seen from Earth with the same angular resolution:

Sadly, they used radio waves, and probably a years long exposure, so I don't think they could actually get this picture, but :bugeyes::bugeyes:


(Dear Mods - is it possible to change the second word of the thread title to "think"? Thank you, Matt)
