It's Henize's N119 nebula in the LMC.  On long-exposure pictures the 
"spiral" becomes an "8" centered on the star cluster SL360 (which hosts 
S Dor).  It also shows up on unfiltered CCD images.

The origin of the nebula's shape is uncertain.  Theories I've heard of 
mention simultaneous supernovae, or intense stellar winds, or bipolar 
outbursts.
