Quote :
Black holes may be one of the universe’s most bizarre phenomena. They’re literally divide-by-zeros in the sky
Um, no they're not.  Literally.

Quote :
“This is going to be a seminal observation in the history of mankind,” Grant Tremblay, observational astrophysicist from Yale University, told Gizmodo. “This image [of Sagittarius A*], whatever it shows, will be in the top ten images ever taken.”
Scientists in search of funding aren't known to exaggerate, are they???

Black holes are considered "black" for a reason.  You can see their effects, but never the black holes themselves.  "Look, a blank spot on the negative!" Woo! Ahhh!

Stuff accumulates near the event horizon, and a lot of energetic action goes on there. So you don't exactly see the black hole itself, but you certainly aren't looking at a blank spot in space, either.
