Apod 1.7


Eclipse at Moonset and Sunrise


Seen from the atop the Chilean coastal mountains looking down upon the pacific ocean under a sea of clouds, is the moon entering into a lunar ellipse. Although the moon is only partially eclipsed in this photo it still gives a wonderful view of the the phenomena that occurred on October 8th, 2014. Lunar eclipses, though not as rare as solar, are not something you get to see ever day. Happening around two to four times a year, a lunar eclipse happens when the moon passes through a portion of the Earth's penumbral or umbral shadows. This process can only occur when the Sun, Earth, and Moon are aligned exactly so that the Earth is in the middle, and the moon is full.
