Sh2-126 Lacerta Nebula

Sharpless 126 (Sh2-126) is a large emission nebula in Lacerta constellation. The source of radiation from the star 10 Lacertae, a blue main sequence star.
This region, also known as the “Great Lacerta Nebula” is part of Lacerta OB1, a giant star-forming region. The blue-green nebula, which forms a "stellar funnel" in the center of the image and meanders away to the right, is labeled LBN 437. It is a molecular cloud, the densest part of which is associated with some bright young stars. Its most striking feature is a symmetric 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 from the star collides with dust clouds.
