Plane Crossing Crescent Moon
Explanation: No, the Moon is not a bow, and no, it did not shoot out a plane like an arrow. What is pictured is a chance superposition. The plane's
contrail would normally appear white, but the large volume of air toward the rising Sun preferentially knocked away blue light, not only making the
sky blue, but giving the reflected trail a bright
red hue. Far in the distance, well behind
the plane, the
crescent Moon also appears slightly reddened. Captured early last month from
Bolton,
UK, the featured image was taken so soon after sunrise that the plane was sunlit from below, as was its contrail. Within minutes, unfortunately, the impromptu sky
show ended. The plane moved out of sight. The
Moon kept rising but became harder to see through a brightening sky. And the
contrail gradually dispersed.
