Subj : Daily APOD Report To : All From : Ben Ritchey Date : Tue Nov 06 2018 06:54:22 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 November 6 [2] NGC 1499: The California Nebula Image Credit & Copyright: Bray Falls [3] Explanation: There's even a California in space. Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud [4] by chance echoes the outline of California [5] on the west coast of the United States [6] . Our own Sun [7] also lies within the Milky Way's Orion Arm [8] , only about 1,500 light-years from the California Nebula [9] . Also known as NGC 1499 [10] , the classic emission nebula is around 100 light-year [11] s long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen [12] atoms recombining with long lost [13] electrons, stripped away ( ionized [14] ) by energetic starlight. The star most likely providing the energetic starlight [15] that ionizes [16] much of the nebular gas is the bright, hot, bluish Xi Persei [17] just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted [18] with a wide-field telescope under a dark sky toward the constellation of Perseus [19] , not far from the Pleiades [20] .
