Encyclopedic overview
NGC 1931 is a reflection and emission nebula and around a young star cluster in the constellation Auriga. The nebula shares similarities to the Orion Nebula as it is a mixed emission-reflection nebula that also contains a small Trapezium of hot young stars. At around 2 million years of age, most of the ongoing star formation in the star cluster is hidden away in the nebula. It is believed that the main ionizing source for the dusty molecular cloud is a single, hot B-type star. The distance from Earth is estimated at 7500 light years.
