                           Astronomy Picture of the Day   
      
       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.

       The featured image shows Jupiter in infrared light as captured by the   
       James Webb Space Telescope. Visible are clouds, the Great Red Spot --   
         appearing light in color -- and a prominent ring around the giant   
         planet. Please see the explanation for more detailed information.

      Explanation: Why does Jupiter have rings? Jupiter's main ring was   
      discovered in 1979 by NASA's passing Voyager 1 spacecraft, but its   
      origin was then a mystery. Data from NASA's Galileo spacecraft that   
      orbited Jupiter from 1995 to 2003, however, confirmed the hypothesis   
      that this ring was created by meteoroid impacts on small nearby moons.   
      As a small meteoroid strikes tiny Metis, for example, it will bore into   
      the moon, vaporize, and explode dirt and dust off into a Jovian orbit.   
      The featured image of Jupiter in infrared light by the James Webb Space   
      Telescope shows not only Jupiter and its clouds, but this ring as well.   
      Jupiter's Great Red Spot (GRS) -- in comparatively light color on the   
      right, Jupiter's large moon Europa -- in the center of diffraction   
      spikes on the left, and Europa's shadow -- next to the GRS -- are also   
      visible. Several features in the image are not yet well understood,   
      including the seemingly separated cloud layer on Jupiter's right limb.
