| This nebula is actually surrounding a large B type star. This star is
a distance of 1600 light years from the sun. B type stars typically have a surface temperature
somewhere in the range of 11,000 - 25,000 Kelvin. In comparison the sun has a
temperature of 5,000 Kelvin. This star forming region has a particle density of
5000 particles per cubic centimeter. The interstellar medium (the space between stars) within
our own galaxy averages 1 particle per cubic centimeter. Compare that
with air near the surface of the Earth which averages 100,000,000,000,000,000,000 molecules per cubic centimeter!
