Okay there was nothing visible in that dimension of space on 4/7/08. Three days later, Japanese astronomers spotted a 7th magnitude NOVA which by all indications, is huge.
I know it doesn't look exciting, until you realize what you're looking at. See the upper light, the brightest light in this picture? That's a star that was already there, in an area of outer space called Cygnus. See the other one? That wasn't there before, now it is. It's a NOVA and this shot was captured by two Italians in New Mexico with a rented scope. The new star is brightening, isn't this wondrous? Isn't life so awesome and inspiring?
