APOD 1.8: October 21, 2011. Clouds of Perseus

The October 21 APOD picture shows a Cosmic cloud consisting of dust and gas. This cosmic cloud spans 17 degrees near the southern edge of the heroic constallation Perseus. The Red cloud in the middle of the panaroma is the red NGC 1499 (common name: California Nebula). The striking red color is caused by the atomyc hydrogen gas that is powered by ultraviolet light coming from the lumious blue star called Xi Persei that is in direct proximity of the California Nebula. The various dust clouds in the image reflect starlight from the Miky way, and are hundreds of light years above the galactic plane.
