Monkey Head Nebula (NGC 2174)
NGC
2174 was discovered in 1877 by Jean Marie
Stephan. Also known as the Monkey Head is a large
molecular cloud, whose dominant emission is in
the hydrogen alpha wavelength, which is ionized
by the energy of the bright stars in the star
cluster in its midst, NGC2175. They are thought
to be about 6400 light years away from us. It
lies very close to the border with Gemini, only
two degrees southwest of supernova remnant
IC
443, and four degrees due south of open cluster
M35.
