Thanks. Unfortunately I'll have to wait until my "free article" count with NYT resets. Meanwhile there will be new thread on the astrophysics bear.

It's an amazing discovery, just as Einstein predicted.

the only thing I don't understand is the orientation of the black hole in relation to us?

That's one interpretation of orientation: position on the night sky. The other possible interpretation (which is the first thought I had when reading the original Q) is: what is the direction of the BH's spin axis w.r.t the plane of the sky at its location. I am curious to find what that might be. I think I'll have to read the paper, but from the images I see only vague hints.

The discovery paper is open access and there is no preferred orientation for Sgr A*. See this thread viewtopic.php?p=201764#p201764
