this lwp depict a picture of space nebula wallpaper in color of redand green an emission nebula is a nebula formed of ionized gasesthat emit light of various colors. the most common source ofionization is high-energy photons emitted from a nearby hot star.space nebula wallpaper. among the several different types ofemission nebulae are h ii regions, in which star formation istaking place and young, massive stars are the source of theionizing photons; and planetary nebulae, in which a dying star hasthrown off its outer layers, with the exposed hot core thenionizing them. usually, a young star will ionize part of the samecloud from which it was born although only massive, hot stars canrelease sufficient energy to ionize a significant part of a cloud.space nebula wallpaper. in many emission nebulae, an entire clusterof young stars is doing the work. the nebula's color depends on itschemical composition and degree of ionization.

due to the prevalence of hydrogen in interstellar gas, and itsrelatively low energy of ionization, many emission nebulae appearred due to the strong emissions of the balmer series. if moreenergy is available, other elements will be ionized and green andblue nebulae become possible. by examining the spectra of nebulae,astronomers infer their chemical content. hd space backgrounds.most emission nebulae are about 90% hydrogen, with the remainderhelium, oxygen, nitrogen, and other elements.
