   We’re celebrating 20 years of Earth Science Picture of the Day during

   past. Thanks to all of our followers (on the blog, Facebook, Instagram
   and Twitter) for supporting us. Thanks also to all of you who’ve
   submitted your photos. We’re most appreciative. This EPOD was
   originally published December 31, 2019.

   The panoramic view above, composed of 4 photos, shows a breathtaking
   set of  anticrepuscular rays as observed just before  sunset at
   Miami Beach, Florida, on November 1, 2019. The camera is facing east
   northeast. Note the  cumulonimbus cloud at the far left. Sunlight
   streaming through the turrets of clouds like this, where  the Sun is
   setting ( opposite of where the camera is facing), may result in
   rays that stretch all the way across the sky. However, a small amount
   of  dust or haze must be present in  the atmosphere for the rays
   to be seen.  Perspective makes them appear to converge in the
   distance. The diagram below, courtesy of Dave Lynch, illustrates how
    crepuscular and anticrepuscular rays are viewed.
