Acrylic Galaxy Nebula Painting

[@jclars8324]

the “white stripey bits” are actually different things if they’re in a galaxy versus a nebula. in a galaxy, the white bits you see correspond to areas with lots of hot, young, blue stars. blue stars are the hottest and brightest stars, and even though they’re blue, when clumped together in high densities, they make the surrounding area look more white. you see this a lot in the centers of galaxies and along the arms of spiral galaxies. in nebulas, different colors correspond to different types of gas and dust in the nebula. since most images of nebulae are false color, this isn’t aways the case, but oftentimes white shows the presence of oxygen, which actually releases green light, though we very often see it as white. anyways, i love this, it reminds me of the veil nebula! i want to try it next time i paint something :) p.s. this is jessie from your class two years ago, if you remember me :)
