According to NASA, the next total lunar eclipse will be on January 31, 2018, and will be seen in Asia, Australia and North America. Penumbral lunar eclipses will occur on March 23, 2016, September 16, 2016, and February 11, 2017. Penumbral eclipses are more difficult to observe because only part of the moon is eclipsed.
