Wolf-Rayet star, WR 134
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.
