First quarter Moon. The lunar phases arise as the Earth-Moon-Sun angle changes as the Moon orbits the Earth. This waxing Moon is 7 days into its 28-day cycle (first quarter). On a waxing Moon, the day-night line (terminator) marks the lunar dawn as sunlight advances over the Earth-facing side of the Moon. This image, published in 2015, uses data from the Lunar Reconnaissance Orbiter. The image is part of a sequence of lunar phases (see images C030/3708-3714), orientated for the northern hemisphere. | |
