Pelican Nebula Ionization Front. The light from young energetic stars is slowly transforming the Pelican's cold gas to hot gas, with the advancing boundary between the two known as an ionization front.

Clouds of Perseus ~ contains over 10,000 solar masses of gas and dust, but the eye is drawn to red NGC 1499. Known as the California Nebula, its characteristic glow of atomic hydrogen gas is fueled by ultraviolet light from luminous blue star Xi Persei. Farther along, intriguing young star cluster IC 348 and neighboring Flying Ghost Nebula. On the outskirts of a giant molecular cloud, another active star forming region, NGC 1333, lies near the edge of the wide field of view.
Finnish astrophotographer J-P Metsävainio observed IC 1396, making a gorgeous image of it. But he wasn’t satisfied just doing that. He’d been playing with making 3D images for some time, and decided this might be a good opportunity to make a model of the structure of the nebula, and then create an animated GIF of it.
