Summary Author: Chris Kotsiopoulos; Jim Foster

The photo above shows a young Moon amidst a sea of “burning” clouds as observed from near Athens, Greece on June 25, 2009 at 8:37 p.m. local time. A few well positioned and reddened clouds, over the darkened portion of this waxing crescent Moon, give the illusion that something nefarious has happened to our reliable companion. At sunset or sunrise the increased path length of sunlight, as compared to when the Sun is overhead or midway between the zenith and the horizon, efficiently extinguishes the shorter wavelengths of light (blues and greens), permitting the sky to be imbued by shades of red, orange and yellow.

Photo details: Canon EOS Rebel XTi; Skywatcher ED 80; shutter speed 1/250; aperture 7.5; ISO 100
