WebBecause this jump is fairly common, HII regions give off a lot of red light. In a tri-color image using red, green and blue filters, HII regions appear pink. (BUT: SDSS tri-color images use the green, red, and near infrared filters to make color images - confusing, no? In SDSS images, HII regions appear light blue instead of pink.) WebHII regions are emission nebulae created when young, massive stars ionise nearby gas clouds with high-energy UV radiation. They are composed primarily of hydrogen, hence …

WebJun 28, 2014 · You probably recall that emission nebulae are commonly referred to as "HII regions". Electrons that have been stripped from the hydrogen atoms can rejoin atoms and resume the process of Balmer decays all over again. This ongoing process is what gives us the reddish-colored nebulae. So that's the technical explanation. You were warned!
