This is one of my favorite objects: the supernova remnant know as the West Veil Nebula, or sometimes, the Witch's Broom Nebula. The supernoa took place before recorded history, but the blast wave continues to ripple through space. The red gas is hydrogen, the blue green is oxygen. Above the lower streamer, you can see Pickering's Triangle, which is part of the Cygnus Loop. The Cygnus Loop is the supernova remnant of which the West Veil is just a part.
