Wolf-Rayet 134

Wolf-Rayet 134

This is a special kind of rare dying star called a Wolf-Rayet that lives about 6,000 light years away in the constellation Cygnus.  I was able to capture it in RGB color with Hydrogen and Oxygen to enhance the nebula regions.  These rare stars are in the dying phase of their star life and begin to run out of hydrogen and begin forming heavier elements.  They shed their outer layers in these intense but faint bubbles that we are able to capture.  It is predicted that these rare stars are leading to a supernova event for the ending of the star.  Only about 500 of these rare stars are currently cataloged.
