On the night of January 20-21, for the third time in less than a year, the Moon will become completely immersed in Earth's shadow and create one of nature's most beautiful spectacles: a total lunar eclipse. Last January 31st, the timing of totality favored the lands around the rim of the Pacific Ocean; those in the western U.S. could catch it before moonset. Then, on July 27th,the longest total lunar eclipse until the year 2123 took place over the Eastern Hemisphere, with no part of that celestial event visible from North America.
