Jay Ouellet
sent us this wonderful photograph that shows earthshine, an interesting phenomenon
of twice-reflected sunlight.
 The
bright portion of the Moon, be it full or crescent, is created by reflected
sunlight. But the dark portion can sometimes appear dimly lit when sunlight
reflects off Earth and hits the Moon, then is reflected back to Earth. The effect
is strongest when the Moon is a thin crescent.
The image was made on May
3 in a suburb of Quebec city called Shannon, where Ouellet's Irish ancestors
came to in 1838. He calls the photograph "A
Touch of Ireland." [Skywatcher's
