 EPOD - a service of USRA

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
relevant links.


 Lunar Mirage and Cruise Ship

   Summary Authors:  Marco Meniero;  Jim Foster

   Shown above is a lunar pedestal that resulted from a  lunar mirage
   ( Etruscan Vase or  omega mirage) observed over the
    Tyrrhenian Sea, near Rome, Italy. It’s juxtaposed here with a gayly
   painted cruise ship. Mirages such as this are caused by  atmospheric
   refraction that occurs when light traverses an unusually warm layer of
   air lying immediately above the sea surface. In order to view these
   sorts of distortions, however, the temperature variation from the
   surface of the sea to a level perhaps 50 ft (15 m) or so above it must
   be quite remarkable. If you look closely you can also detect
    earthshine. Photo taken on January 17, 2021.

   Photo Details: Eos 1DxmK2 camera; Canon EF 400 lens; 2..8 + 1.4X;
   equivalent focal is 900.
