Subj : Daily APOD Report To : All From : Ben Ritchey Date : Mon May 13 2019 07:20:37 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. 2019 May 13 [2] Rho Ophiuchi Wide Field Image Credit & Copyright: Mario Cogo [3] (Galax Lux [4] ) Explanation: The colorful clouds surrounding the star system Rho Ophiuchi compose one of the closest star forming regions. Rho Ophiuchi itself [5] is a binary star system [6] visible in the blue reflection nebula just to the left of the image center. The star system, located only 400 light years [7] away, is distinguished by its multi-colored surroundings [8] , which include a red emission nebula [9] and numerous light and dark brown dust lanes. Near the lower left of the Rho Ophiuchi molecular cloud system [10] is the yellow star Antares [11] , while a distant but coincidently-superposed globular cluster [12] of stars, M4 [13] , is visible just to the right of Antares. Near the image top lies IC 4592, the Blue Horsehead nebula [14] . The blue glow that surrounds the Blue Horsehead's eye -- and other stars around the image -- is a reflection nebula composed of fine dust. On the featured image [15] right is a geometrically angled reflection nebula cataloged [16] as Sharpless 1 [17] . Here, the bright star near the dust vortex creates the light of surrounding reflection nebula [18] . Although most of these features [19] are visible through a small telescope pointed toward the constellations of Ophiuchus [20] , Scorpius [21] , and Sagittarius [22] , the only way to see the intricate details of the dust swirls, as featured above, is to use a long exposure [23] camera.
