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 April 23
    [2]A skyscape is shown over a rocky landscape. In the starry sky are
   the central band of our Milky Way Galaxy on the left, a meteor trail on
      the right, the dim band of zodiacal light in the center, and the
     photographer holding a light just below the center. The path of the
     light is shown as a bright streak in the bottom part of the frame.
          Please see the explanation for more detailed information.

                          An Almost Everything Sky

   Explanation: This surprising sky has almost everything. First, slanting
   down from the upper left and far in the distance is the [4]central band
   of our [5]Milky Way Galaxy. More modestly, slanting down from the upper
   right and high in [6]Earth's atmosphere is a [7]bright meteor. The dim
   band of light across the central diagonal is [8]zodiacal light:
   sunlight reflected from [9]dust in the inner [10]Solar System. The
   green glow on the far right is [11]aurora high in [12]Earth's
   atmosphere. The bright zigzagging bright line near the bottom is just a
   light that was held by the scene-planning [13]astrophotographer. This
   "[14]almost everything" sky was captured over rocks on [15]Castle Hill,
   [16]New Zealand late last month. The featured [17]finished frame is a
   combination of 10 exposures all taken with the same camera and from the
   same location. But what about the astrophotographer himself? He's
   pictured too -- can you [18]find him?
