       Discover the cosmos! Each day a different image or photograph of our   
         fascinating universe is featured, along with a brief explanation

       A starfield is shown that has a bright comet. The comet shows a green   
         head on the lower left and an ion tail with significant structure   
       extending out to the upper right. Please see the explanation for more   
                               detailed information.

      Explanation: Comet Lemmon is brightening and moving into morning   
      northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6   
      (Lemmon) is now the third comet currently visible with binoculars and   
      on long camera exposures. Comet Lemmon was discovered early this year   
      and is still headed into the inner Solar System. The comet will round   
      the Sun on November 8, but first it will pass its nearest to the Earth   
      -- at about half the Earth-Sun distance -- on October 21. Although the   
      brightnesses of comets are notoriously hard to predict, optimistic   
      estimates have Comet Lemmon then becoming visible to the unaided eye.   
      The comet should be best seen in predawn skies until mid-October, when   
      it also becomes visible in evening skies. The featured image showing   
      the comet's split and rapidly changing ion tail was taken in Texas, USA   
      late last week.
