Crepuscular rays and shadows at sunset near Charlo, Montana, US
Contrails and contrail shadows present themselves in this unique atmospheric optical phenomena, wherein the shadows are created when the sun (or moon) casts a shadow of an aircraft contrail onto a lower layer of clouds or haze. The interplay of light, clouds, and ice crystals, coupled with one's viewing angle, gives rise to a captivating display in the sky, as seen here during sunset over Falls Church, Virginia, US.
