Nebulosak Zefeo konstelazioan

Dark and bright nebulae in Cepheus

 

 

Chepeus B hodeiaren ertzean (Cepheus hodei molekularreren zatia), Sh2-155 edo Leize-zulo nebulosa Cepheus (Zefeo) konstelazioan kokatua dagoen nebulosa hedatua da, nebulosa igorle, erreflexu eta ilun barne dituen nebulosa konplexu handi baten eremu. Sh2-155 ionizatutako HII eremuda da non izarrak sortzen ari diren, Lurretik 2400 argi-urtera kokatirik.

At the edge of the Cepheus B cloud (part of the Cepheus molecular cloud),  Sh2-155 or Cave Nebula is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. Sh2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth.
