afro-dominicano: NGC 7822 Processing: Francesco Antonucci; Data: WISE IRSA Archive A young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 pc distant, with the younger components aged no more than a few million years.
Pinner writes: "NGC 2264 is a young triangular-shaped open cluster of stars embedded in a star-forming cloud, located around 2600 light-years away in the north-eastern corner of the constellation of Monoceros."
IC 405 is named the Flaming Star Nebula,The material that appears as smoke is mostly interstellar hydrogen, but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible near the nebula center, is so hot it is blue, emitting light so energetic it knocks electrons away from surrounding gas. When a proton recaptures an electron, red light is frequently emitted, as seen in the surrounding emission nebula.
Witch's Broom Nebula: The Witch's Broom Nebula is also part of the famous Veil Nebula complex, this being the western portion. The entire complex is the remnant of a powerful supernova explosion which occurred thousands of years ago, sending elements forged in the destroyed stars core into space. The bright star is 52 Cygni.
Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan, popularly called the Tulip Nebula with a glowing cloud of interstellar gas and dust. - Image Credit & Copyright: J-P Metsävainio (Astro Anarchy)
NGC 7635: Bubble Nebula, an H II region emission nebula in Cassiopeia. The 'bubble' is created by the stellar wind from a massive hot, 8.7 mag. young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble itself being excited by the hot central star, causing it to glow. The star SAO 20575 is thought to have a mass of 10-40 Solar masses Wikipedia
