Outer space+black holes
"Can you bind the cluster of the Pleiades, or loose the belt of Orion? Can you bring out the Mazzaroth in its season? Or can you guide the Great Bear with its cubs?" (Job 38:31-33).
A Fox Fur, a Unicorn, and a Christmas Tree Nebula. A star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae.
This image shows the edge of a giant gaseous cavity within the star-forming region called NGC 3324. The glowing nebula has been carved out by intense ultraviolet radiation and stellar winds from several hot, young stars. A cluster of extremely massive stars, located well outside this image in the center of the nebula, is responsible for the ionization of the nebula and excavation of the cavity.
