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.


 Rainbow Flashes

    Rainbow Flahes on Dschubba and Mars

   Photographer:  Dario Giannobile

   Summary Author:  Dario Giannobile

   This photo compilation features an optical effect called  Green
   Flash for the planet  Mars and star  Dschubba. Green ray is a
   phenomenon caused by the  refraction of incoming light as it passes
   through thick layers of the  atmosphere. Shorter wavelengths refract
   more strongly than longer red wavelengths, and color separation gives a
   green hue to the last visible ray of our luminous object. Green ray
   evidence is extremely common on the solar disk but much rarer on the
    Moon and planets. Even more peculiar is a separation of the light
   that can lead to the observation of a  blue-tinted flash. A
   telescope or telephoto lens and camera can help capture this
   tantalizing result of atmospheric refraction when celestial bodies are
   close to the horizon. This one-of-a-kind image shows for the first time
   the phenomenon in its entirety during the rising of the star Dschubba
   of the constellation   Scorpius  (delta Scorpii). Various flashes
   have been created around the star that have taken on the tints of the
   rainbow, shifting from red (in the lower edge of the star) to blue /
   purple in the upper edge. The same phenomenon happened shortly after
   during the rising of Mars which presented different flashes and colors
   mainly of red and green.
