This object also often called the Omega Neblula or rarely the
Horseshoe Nebula. This image is deep enough that the "swan-ness" of the
nebula is lost in the convoluted turmoil of gas and dust. However if
you squint at the screen, you will find that the brightest parts of the
nebula make a convincing bird floating on the water with the head (dark
area) on the left and the wings extending up and to the right.
The body of the Swan is about twelve lightyears long, but that
is only the brightest portion. There are fainter, irregular clumps of gas
that stretch for forty lightyears or more.
The Swan is about 5700 lightyears away towards the constellation of Sagittarius.
