Hints: telescope NGC 1068 Andromeda Dressler Nuker John Kormendy 1’15’处有一冒号（: ）

When the results came down from the telescope he saw something that was completely unexpected. The picture from the active galaxy where he hoped to find a black hole was unreadable. NGC 1068 was just too far away for the telescope to get a clear picture. The surprise came from Andromeda, the quiet, normal galaxy right next to us.
I was astonished when I found what I was looking for, but not where I was looking for it. This jog in this dark band shows that on one side the stars are moving very rapidly away from us at 150 kilometers a second which is 500,000 kilometers an hour.
Dressler thought there could only be one thing that would cause the stars to move this fast: a supermassive black hole and he wasn't alone. Fellow Nuker John Kormendy had found exactly the same thing.
