Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                               2022 October 16
    [2]The featured image shows a the big beautiful barred spiral galaxy
    NGC 1300 with encompassing spiral arms tinted blue from young stars.
          Please see the explanation for more detailed information.

   Explanation: Across the center of this spiral galaxy is a [6]bar. And
   at the center of this bar is smaller [7]spiral. And at the center of
   that spiral is a [8]supermassive black hole.  This all happens in the
   big, beautiful, [9]barred spiral galaxy cataloged as NGC 1300, a galaxy
   that lies some 70 million light-years away toward the [10]constellation
   of the river Eridanus. This [11]Hubble Space Telescope [12]composite
   view of the gorgeous [13]island universe is one of the [14]most
   detailed Hubble images ever made of a complete galaxy. [15]NGC 1300
   spans over 100,000 [16]light-years and the Hubble image reveals
   striking details of the galaxy's dominant central bar and majestic
   spiral arms. How the giant bar formed, how it remains, and how it
   affects [17]star formation remains an [18]active topic of research.
