                                Explanation:

        Once upon a midnight dreary, while I pondered weak and weary,
                O'er volumes of astronomy and forgotten lore,
              I stumbled upon this snapshot, cosmic and eerie,
               A sight that filled my heart with awe and more.

             Two stars, like sentinels, anchored the foreground,
                 Of our Milky Way galaxy, a sight to behold,
              Beyond them, a cluster of Hydra, galaxies abound,
              100 million light-years away, a story to be told.

            Three large galaxies, ellipticals and a spiral blue,
             Dominant and grand, each 150,000 light-years wide,
            But it was the overlapping pair that caught my view,
                Cataloged as NGC 3314, a sight I cannot hide.

                Abell 1060, the Hydra galaxy cluster's name,
         One of three large galaxy clusters close to our Milky Way,
               A universe bound by gravity, a celestial game,
           Where clusters align over larger scales, I cannot sway.

       At a distance of 100 million light-years, this snapshot's size,
              1.3 million light-years across, a cosmic delight,
               A momentary glimpse into the universe's guise,
            But even this shall fade, and be nevermore in sight.
