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

Lunar Mirage and Cruise Ship

April 01, 2021


Photographer: Marco Meniero
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.
