Remix Nebula - cloud of dust, hydrogen, helium and other gases that attract matter and materials to clump. These so called clumps form stars, planets, and other planetary systems. Nebulae are where the stars are formed!
This image from Nasa's Spitzer Space Telescope shows a stellar nursery containing thousand of young stars & developing protostars near the sword of the constellation Orion. I heart the Spitzer space telescope.
