This faint emission nebula lies about 12,000 light-years away in the northern constellation Auriga. Doubly ionized oxygen dominates the core of this region. Notable near the 2 o'clock position in this view are two relatively dense streamers of material trailing toward the nebula's central regions. These "tadpoles" are sites of ongoing star formation. Each one is about 10 light-years long.

The complexity of this nebula displays well in Ha alone as shown here.
