Explanation: Have you seen the Moon lately [5] ? On April 18, its waxing
sunlit crescent moved through planet Earth's night across a background of
stars in the Hyades [6] . Anchored by bright star Aldebaran, the nearby,
V-shaped star cluster and complete lunar orb appear in this telephoto image.
The engaging skyview [7]  is actually digitally composed from a series of
varying exposures. Recorded in 1/60th of a second, the shortest in the series
captures the Moon's bright crescent in sharp detail. Longer exposures, ranging
up to 15 seconds, capture fainter background stars as well as earthshine,
visible [8]  to the eye as the earthlit lunar night side [9] .
