[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 April 13 [2] Rigil Kentaurus and Sandqvist 169 Image Credit & Copyright [3] : Roberto Colombari [4] Explanation: Rigil Kentaurus [5] is the bright star near the top of this broad southern skyscape. Of course it's probably better known as Alpha Centauri [6] , nearest star system to the Sun. Below it sprawls a dark nebula complex [7] . The obscuring interstellar dust clouds include Sandqvist catalog [8] clouds 169 and 172 in silhouette against the rich starfields along the southern Milky Way. Rigil Kent is a mere [9] 4.37 light-years away, but the dusty dark nebulae lie at the edge of the starforming Circinus-West [10] molecular cloud about 2,500 light-years distant. The wide-field of view [11] spans over 12 degrees (24 full moons) across southern skies.
