Image Description and Details : Sharpless 126 (Sh2-126) is the designation of a large emission nebula in Lacerta, which appears in this image as a red background and exceeds the edges of the image. The source of its ionization is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star.

The nebula, which forms a "stellar funnel" in the center of the image and snakes away to the right, is designated LBN 437. It is a molecular cloud whose densest part is associated with some bright young stars. Its most striking feature is a symmetrical reflection nebula associated with the Herbig Ae / Be star V375 Lacertae. This star is also responsible for the bipolar Herbig-Haro objects within the nebula. Herbig-Haro objects are small nebulae around young stars. They form when gas ejected by the star hits dust clouds.
