A Two Percent Moon

A young crescent moon can be hard to see. That’s because when the Moon shows it’s crescent phase (young or old) it can never be far from the Sun in planet Earth’s sky. And even though the sky is still bright, a slender sunlit lunar crescent is cleary visible in this early evening skyscape. The telephoto snapshot was captured on August 24, with the Moon very near the western horizon at sunset. Seen in a narrow crescent phase about 1.5 days old, the visible sunlit portion is a mere two percent of the surface of the Moon’s familiar nearside. At the Canary Islands Space Centre, a steerable radio dish for communication with spacecraft is titled in the direction of the two percent Moon. The sunset sky’s pastel pinkish coloring is partly due to fine sand and dust from the Sahara Desert blown by the prevailing winds.
