Sobre Cave Nebula
Descrição
The Cave Nebula (Sh2-155) is an emission nebula and dim HII region in Cepheus, about 2,400 light-years away. It lies at the edge of the Cepheus B molecular cloud and contains active star formation.
Dicas de Observação
A challenging visual target requiring dark skies and at least an 8-inch telescope. An OIII or UHC nebula filter is essential. The nebula appears as a faint, irregular glow with a dark intrusion. Best observed in autumn evenings when Cepheus is near the zenith.
História
Cataloged by Stewart Sharpless in his 1959 catalog of HII regions as Sh2-155. The name "Cave Nebula" comes from the dark lane that appears to cut into the bright emission region.
Curiosidades
The Cave Nebula sits at the boundary between a hot ionized bubble blown by massive stars and a dense molecular cloud. This interface triggers new star formation.
