Explanation:
In the constellation of the
swan near the nebula of the
pelican lies the gas cloud of the
butterfly surrounding a star known as the
hen.
That star, given the proper name
Sadr, is visible to the unaided eye but found here
as the brightest object on the upper left.
Sadr, at 1500 light years distant, is near the center of the
Butterfly Nebula (IC 1318) in a bright region given the comparatively staid label
of IC 1318B.
The
fantastic starfield that surrounds
Sadr
contains stars old and young, an
open cluster of stars
(NGC 6910
visible on the image left), vast clouds of
hydrogen gas that glow red,
and picturesque pockets and filaments of dark
dust.
The above image is a digital fusion of several different
color images of the gamma Cygni (Sadr) region
