NGC 2023
This nebula surrounds a large B type star at 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 Kelvins. In comparison the sun has a temperature of 5,000 Kelvins. 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!
