       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.

       A starfield is shown above a grassy field with hills on the horizon.   
       The band of our Milky Way Galaxy arches across toward the right. Many   
       streaks appear emanating out from a place on the Milky Way just above   
      the horizon. Please see the explanation for more detailed information.

      Explanation: Where are all of these meteors coming from? In terms of   
      direction on the sky, the pointed answer is the constellation of   
      Perseus. That is why the meteor shower that peaks tonight is known as   
      the Perseids -- the meteors all appear to come from a radiant toward   
      Perseus. In terms of parent body, though, the sand-sized debris that   
      makes up the Perseids meteors come from Comet Swift-Tuttle. The comet   
      follows a well-defined orbit around our Sun, and the part of the orbit   
      that approaches Earth is superposed in front of Perseus. Therefore,   
      when Earth crosses this orbit, the radiant point of falling debris   
      appears in Perseus. Featured here, a composite image taken over six   
      nights and containing over 100 meteors from 2024 August Perseids meteor   
      shower shows many bright meteors that streaked over the Bieszczady   
      Mountains in Poland. This year's Perseids, usually one of the best   
      meteor showers of the year, will compete with a bright moon that will   
      rise, for many locations, soon after sunset.
