The combination of colors in this bubble nebula is amazing. However do not let the pretty colors and the bubbly nature fool you. The center of the bubble is an O star. Because of their high temperatures the luminosities of main sequence O stars range from 10,000 times the sun to around 1,000,000 times, giants from 100,000 times the sun to over 1,000,000, and supergiants from about 200,000 times the sun to several million times! This nebula in particular lies 11,000 ligth years away from the constellation Cassiopeia.
