Clouds of Perseus ~ contains over solar masses of gas and dust, but the eye is drawn to red NGC Known as the California Nebula, its characteristic glow of atomic hydrogen gas is fueled by ultraviolet light from luminous blue star Xi Persei.
A towering "mountain" of cold hydrogen gas laced with dust is the site of new star formation in the Carina Nebula. The great gas pillar is being eroded by the ultraviolet radiation from the hottest newborn stars in the nebula.

An uncommon view of the Rosette Nebula, revealing the rose's long stem. Located within the constellation Monoceros, the Rosette (NGC is about light years away from Earth. At the center of the rose blossom is an energetic star cluster, Caldwell
is the designation for a region of glowing hydrogen gas surrounding an association of young stars in the Large Magellanic Cloud, a nearby, small companion galaxy to the Milky Way visible from the Southern Hemisphere.
Giant blue stars ionizing hydrogen gas give dwarf galaxy IC 10 its signature blue glow and signal ongoing star formation. IC 10 is in our Local Group which is dominated by the Milky Way and Andromeda Galaxy.
"Central Cygnus Skyscape" - In cosmic brush strokes of glowing hydrogen gas, this beautiful skyscape unfolds across the plane of our Milky Way Galaxy and the center of the northern constellation Cygnus the Swan.
