I found something amazing when comparing my 2926 data to Hubble’s 1999 image of Messier 1 – Crab Nebula. In 26 years the Nebula has grown a substantial amount! In this video I talk a little about what M1 is and then around the 1:58 minute mark I show you an overlay of Hubble’s image vs my own. In the image you’ll see stars that were once outside of the nebula have now been covered by the rapidly expanding walls of the supernova.

Very cool! The nebula was created in 1054 and had 1045 years to reach the size in the 1999 Hubble image. 27 years later would, at constant expansion velocity of the leading edge, imply a size increase of 27/1045 = 0.026. That estimate looks llke its in the ballpark of what you see, maybe a bit bigger? (Due to effects of gravity?)
