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.

       [2]The featured image shows the interacting Cartwheel Galaxy as
     captured in visible and infrared light by the Webb Space Telescope.
          Please see the explanation for more detailed information.

   Explanation: To some, it looks like a wheel of a cart. In fact, because
   of its outward appearance, the presence of a central [7]galaxy, and its
   connection with what looks like the spokes of a wheel, the galaxy on
   the right is known as the [8]Cartwheel Galaxy. To others, however, it
   looks like a [9]complicated interaction between galaxies awaiting
   explanation. Along with the two galaxies on the left, [10]the Cartwheel
   is part of a [11]group of galaxies about 500 million light years away
   in the [12]constellation Sculptor. The large galaxy's rim spans over
   100,000 [13]light years and is composed of star forming regions filled
   with extremely bright and massive stars. The Cartwheel's ring-like
   shape is the result of gravitational disruption caused by a smaller
   galaxy passing through a large one, compressing the interstellar gas
   and dust and causing a [14]star formation wave to move out like a
   [15]ripple across the surface of a pond. [16]The featured recent image
   of the [17]Cartwheel Galaxy by the [18]Webb Space Telescope reveals
   [19]new details not only about where stars are forming, but also about
   activity near the galaxy's [20]central black hole.
