Explanation: If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe of about 100 billion stars, 32 million light-years away toward the constellation PiscesM74 presents a gorgeous face-on view. Classified as an Sc galaxy, the grand design of M74’s graceful spiral arms are traced by bright blue star clusters and dark cosmic dust lanes. The above image covers half the width of the full Moon and was obtained using 19 hours of exposure on the 1.23-meter telescope at Calar Alto Observatory in the Sierra de Los Filabres mountain range in Spain. Spanning about 30,000 light-years across the face of M74, it includes exposures recording emission from hydrogenatoms, highlighting the reddish glow of the galaxy’s large star-forming regions.
