Sharpless 112, Emission Nebula
This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. Sharpless 112 is an emission nebula. It is glowing deep red because the hydrogen gas in the nebula is energized by the star BD +45 3216 embedded within. This star is much more massive than our Sun, and emits copious amounts of ultraviolet (UV) light that causes the gas to glow. The image was generated with observations in B (blue), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is right, East is up.
