Subj : Daily APOD Report To : All From : Ben Ritchey Date : Wed Jan 30 2019 09:40:48 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 January 30 [2] Wide Field View of Great American Eclipse Image Credit & Copyright: Nicolas Lefaudeux [3] Explanation: Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona [4] , the sun's outer atmosphere [5] , is an alluring sight. But the subtle details and extreme ranges [6] in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured here [7] , however, using over 120 images and meticulous digital processing, is a detailed wide-angle image of the Sun's corona taken during the Great American Eclipse [8] in 2017 August. Clearly visible are intricate layers [9] and glowing caustics of an ever changing mixture of hot gas and magnetic fields [10] . Hundreds of stars as faint as 11th magnitude [11] are visible behind the Moon and Sun, with Mars [12] appearing in red on the far right. The next total eclipse of the Sun [13] will occur on July 2 and be visible [14] during sunset from a thin swath across Chile [15] and Argentina [16] .
