I was listening to Quirks and Quarks the other day and heard a story about the Event Horizon Telescope project where they take a half dozen telescopes from around the world, some atomic clocks and a few computers and take a picture of the black hole at the center of the galaxy. Just a wee fellow with the mass of 4 million suns and 26k light years away. Even while the thing itself is totally black and emits no light it is surrounded by a cloud of billion degree gas that is the brightest thing around. Apparently we will get a look at the shadow of the thing in a year or so.
Mind = blown.
Anyway, my question is how do you see through that cloud of gas?
