Astronomy Picture of the Day

   [1]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.

                               2025 August 20
    [2]A deep sky is shown with the band of our Milky Way Galaxy running
     from the upper left to the lower right. The streaks or many curved
     meteors are seen. In the foreground a beach is seen with an unusual
    rock outcrop that has an opening. Please see the explanation for more
                            detailed information.

   Explanation: What are those curved arcs in the sky? Meteors --
   specifically, meteors from this year's [4]Perseid meteor shower. Over
   the past few weeks, after the sky darkened, many images of [5]Perseid
   meteors were captured separately and merged into a single frame, taken
   earlier. Although the [6]meteors all traveled on straight paths, these
   paths appear slightly curved by the wide-angle lens of the capturing
   camera. The meteor [7]streaks can all be traced back to a single point
   on the sky called the [8]radiant, here just off the top of the frame in
   the [9]constellation of Perseus. The same camera took a deep image of
   the background sky that brought up the [10]central band of our
   [11]Milky Way galaxy running nearly vertically through the [12]featured
   image's center. The limestone arch in the foreground in [13]Dorset,
   [14]England is known as [15]Durdle Door, a name thought to survive from
   a thousand years ago.
