- NGC_2023 abstract "The reflection nebula NGC 2023 is in the constellation Orion. It is one of the brightest sources of fluorescent molecular hydrogen, and at 4 light-years wide it is one of the largest in the sky. It is powered by the B star (B1.5) HD 37903, the most luminous member of a cluster of young stellar objects illuminating the front surface of the Lynds 1630 molecular cloud (Barnard 33) in Orion B.NGC 2023 forms a cavity in the surface of the cloud, some 450 parsecs from Earth. It produces a bright visual reflection nebula and an ultraviolet-excited photodissociation region. It is about a third of a degree from the Horsehead Nebula and is often included (but not indicated) in images of that object.".
