[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 29 [2] M95: Spiral Galaxy with an Inner Ring Image Credit: NASA [3] , ESA [4] , Hubble [5] , ESO [6] , Amateur Data; Processing & Copyright: Robert Gendler [7] & Roberto Colombari [8] Explanation: Why do some spiral galaxies have a ring around the center? First and foremost, M95 [9] is one of the closer examples of a big and beautiful barred spiral galaxy [10] . Visible in the featured combination [11] of images from Hubble [12] and several ground based telescopes are sprawling spiral arms delineated by open clusters [13] of bright blue stars [14] , lanes of dark dust, the diffuse glow of billions of faint stars, and a short bar [15] across the galaxy center. What intrigues many astronomers, however, is the circumnuclear ring [16] around the galaxy center visible just outside the central bar. Although the long term stability of this ring [17] remains a topic of research [18] , observations indicate its present brightness is at least enhanced by transient bursts of star formation. M95 [19] , also known as NGC 3351, spans about 50,000 light-years [20] , lies about 30 million light years away, and can be seen with a small telescope [21] toward the constellation of the Lion (Leo [22] ).
