What is behind the Veil?
Thousands of years ago, there was a massive supernova explosion in the constellation Cygnus. The remnants of this explosion formed a nebula called the Cygnus Loop. It looks like this:
Cygnus Loop is about 120 light-years across and has a magnitude of +5. It is believed to be around 20,000 light years away from us. The Swan Loop is also called the Veil Nebula. The leftmost filament of the veil is commonly referred to as the eastern veil, the middle part is the central veil, and the rightmost part is the western veil.
The Veil was first recorded by William Herschel in 1784.
The eastern and western sails are both worth a closer look, so here they are:
