      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

     [2]The picture shows a clear night sky from Brazil that is not only
   reflected from standing water but by a person holding a mirror. Please
             see the explanation for more detailed information.

   Explanation: What's that in the mirror? In the featured image of the
   dark [4]southern sky, the three [5]brightest galaxies of the night are
   all relatively easy to identify. Starting from the left, these are the
   [6]Small Magellanic Cloud (SMC), the [7]Large Magellanic Cloud (LMC),
   and part of the central band of our [8]Milky Way Galaxy. All three are
   also seen reflected in a shallow pool of water. But what is seen in the
   mirror being positioned by the [9]playful astrophotographer? Dust
   clouds near the [10]center of our Milky Way -- and the planet
   [11]Jupiter. The composite was [12]carefully planned and composed from
   images captured from the same camera in the same location and during
   the same night in mid-2019 in [13]Mostardas, south [14]Brazil. The
   picture won first place in the Connecting to the Dark division of the
   [15]International Dark-Sky Association's [16]Capture the Dark contest
   for 2021.

     Quiz: [17]What is pictured in the double-reflection below the main
                                   mirror?
