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."
