The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and

   Summary Author:  Zdenek Bardon:  Jim Foster

   During an observing session from the  ESO Observatory in Chile one
   night this past November, in addition to various nebulae and star
   clusters, I also captured a patch of light, at center, called the
    Gegenschein or counterglow. Particles of dust and ice in the path
   of Earth’s orbit around the Sun scatter sunlight both forwards and
   backwards, depending upon their size. The  backward scattered light
   is scattered (by smaller particles) with reduced intensity, so the
   resulting dim glow is only visible (to the naked eye) in extremely dark
   skies -- seen at the point in the night sky that’s opposite of the Sun
   ( antisolar point). As with nearly all faint objects, you’ll have
   better luck viewing it if you use  averted vision. Photo taken on
   the night of November 27, 2022.

   Photo details: Nikon D810Da camera with ZEISS Otus 1.4/55 lens; stack
   of 27 images, each with an exposure of 60 seconds.
