Witch Head Nebula - IC 2118

Sorgin Buru Nebulosa - IC 2118

 

 

Witch Head Nebula (IC 2118) is a faint reflection nebula in the Eridanus constellation at about 900 light years. Still to be determined, its believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in Orion. Blue color is determined by the nature of the dust particles contained in the nebula by reflecting better blue than red. Radio observations confirmed substantial carbon monoxide emission throughout parts of the nebula, an indicator of the presence of molecular clouds where stars are forming.

Sorgin Buru nebulosa (IC 2118) Eridano konstelazioan 900 argi-urtera dagoen distira ahuleko islada-nebulosa da. Oraindik argitzeke dagoen arren gertu dagoen Orion konstelazioko Rigel izar erraldoiak argiztatzen duen, aintzinako supernoba baten hondarrak edo izar hodeia dela uste da. Kolore urdina nebulosaren partikulen izaerak ematen dio, kolore urdina gorria baino hobeto islatuz. Irrati uhin bidezko behaketek karbono-monoxidozko emisio nabarmena baieztatu dute nebulosaren gune zehatzetan, non izarrak sortzen ari diren hodei molekularren presentziaren adierazle.
