I could have phrased that better, such as "the supernova was observed on July 4th, 1054 AD." But you are of course correct. Point taken, John; thanks.

The nebula is several thousand light years away, however, so the supernova actually occurred several millennia BCE. People so often seem to forget that the universe we see today is only an image of the universe as it existed thousands or millions of years ago, depending on what you're looking at. It's the closest thing we have to an ability to travel back in time.
