There Are No Green Stars, But ‘Green Galaxies’ Are Real

“Stars can be red, orange, yellow, white, or blue: a spectacular but incomplete color palette. Stars shine simply because they’re matter, heated up to a specific temperature. They emit a broad spectrum of light, with light’s spectral peak determining what we see. But where “green” peaks, we observe all the colors; hence they appear white. Similarly, the hottest stars only appear bluish, as even intense violet light is joined by many other colors. But all throughout the cosmos, we frequently observe green light.”

Look out at the Universe, and there’s plenty of green to be seen. From Earth’s aurorae to the comas of comets, to the glowing green halos around planetary nebulae to what are now known as “green pea” galaxies, which appear green in all sorts of telescopes, including Hubble, there are many green objects. But if there are no such things as green stars, how do these cosmic “green” objects get their color? 

Science has the explanation, and it’s not only amazing, but beautiful as well.
