The Spider and The Fly
Explanation: Will the spider ever catch the fly? Not if both are large emission nebulas toward the constellation of the Charioteer (
Auriga). The
spider-shaped gas cloud on the left is actually an emission nebula labelled
IC 417, while the smaller fly-shaped cloud on the right is dubbed
NGC 1931 and is both an emission nebula and a reflection nebula. About 10,000
light-years distant, both nebulas harbor young, open star clusters. For scale, the more compact
NGC 1931 (Fly) is about 10 light-years across.
