Check out how much this supernova has expanded in 75 years.
I spent over a month capturing images of Messier 1 to compare it to Hubble’s 1999 image and Walter Baade’s 1950 image. By doing so, you can see how much the nebula has expanded in the last 75 years.

This is really cool. Do we have any sense of distance that the plume has expanded and at what speed?
This is pretty great, but also it’s “over”, not “in”, and *so many folks* are going to ignore this over a basic English error
