Description

It is a large emission nebula located about 1,200 light years from Earth in the constellation Lizard (nestled between the constellation Andromeda, Cassioppea, Chepeus and Cygnus). The "red" part is Sharpless-126 (Sh2-126). The source of its ionization is intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star visible to the naked eye. This type of star is rare: it is estimated that there are no more than 20,000 in the whole of the Milky Way. The molecular cloud representing a lizard is LBN437. At the level of its "head" are many bright stars formed from the cloud. Still at the level of its "head", there is a whitish X-shaped structure, it is a Herbig-Haro object associated with the young star V375. These objects are the birthplace of stars and are formed when gas ejected by the star collides with clouds of gas and dust nearby.
