Monkey Head (NGC 2174) is an emission nebula strong in Hydrogen alpha about 6,400 light years away in the constellation of Orion. In the same field of view is the Jellyfish nebula (IC443 or SH2-248), a supernova remnant, about 5,000 light years away just over the border in the constellation of Gemini.
