About the Nebula:

At a distance of 1200 light years, the Horse Head Nebula is located in

the constellation Orion.  Designated as IC 434 it can be found just

below the lower star in Orion’s belt, Zeta Orionis.  Although the

nebula itself is invisible through most telescopes, it shows up on long

time exposures.  The red glowing gas results from hot young stars

which give off ultraviolet radiation.  This radiation ionizes the

surrounding gas cloud causing it go glow red.  The horse head shape

results from a dark gas cloud in front of the red gas cloud.
