Supernova Factory in NGC 2770 (APOD 18 Jan 2008)
I am somewhat new to this.......when the picture caption says an event "recently" occurred, does that mean we recently saw it or that it actually just occurred? If the galaxy is 90 million light-years away, does that mean that the recently viewed supernova occurred 90-million years ago?
