This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. WR 134 is the brightest star below the center of the image. It is a Wolf-Rayet star, which is a very hot, massive star that is blowing off its outer layers. The layers are blown off at very high speeds. Part of these layers can be seen as the blue arc in the upper-left part of the image. The arc was created when the outer layer collided with the ambient nebula surrounding the star. The image was generated with observations in Hydrogen alpha (red) and Sulphur [SII] (blue) filters. In this image, North is left, East is down.

Made with narrow and broad band filters, this colorful cosmic snap shot covers a field of view about the size of the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 50 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernovae enrich the interstellar material with heavy elements to be incorporated in future generations of stars.
