Don Bouc Astrophotography
Distance: 6,500 light years
Radius: 5.5 light years
What is it?: This is one of my top5 favorite images. In 1054 A.D., the Chinese noticed a "daytime star" in the sky. Since then, astronomers used the location they described and found this supernova remnant. This is what remains from that explosion almost 1,000 years ago. It continues to expand at almost 1,000 miles/hour. In the middle of this nebula is a neutron star.

What is it?: This supernova remnant was formed when a very large star exploded about 30,000 years ago. A neutron star was created from that explosion.
Neutron stars are unfathomably dense. Imagine a cruise ship compressed to the size of the tip of a ball point pen...that's close to what a neutron star is made of.
The large, red hydrogen region to the upper left is Sh2-249.

What is it?: This monstrous supernova remnant is fascinating.
A huge star exploded about 10,000 years ago causing this nebula.
It is still expanding at about 200,000 miles/hour. Although it can't be seen, a neutron star or black hole is at the center.
I took three images of "pieces" of this remnant and stiched them together for this picture. Those three pieces are on the following pages of this website.

What is it?: As you can see from the previous picture on this website, this nebula is the "top most" nebula of the Cygnus Loop or Veil Nebula.
When the star that exploded to cause this supernova, it would have been bright enough to be easily visable during the day for a few weeks.

Distance: 2,500 light years
Radius: 65 light years
What is it?: As you can see from a previous picture on this website, this nebula is the "centermost" nebula of the Cygnus Loop or Veil Nebula.
The exploding star that caused all this was 20 times larger than our sun.

What is it?: As you can see from a previous picture on this website, this nebula is the "bottom most" nebula of the Cygnus Loop or Veil Nebula.
Supernova explosions, like that one caused this, seed interstellar space with heavy elements that help create new stars and planets.
