Cloud in outer space (6)

I believe the answer is:

nebula

(Other definitions for nebula that I've seen before include "Bright patch in sky caused by distant galaxy" , "Unable to find patch in the sky" , "Cosmic cloud" , "Unable (anag)" , "Interstellar gas cloud" .)

I've seen this clue in The New York Times.
