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.
With all the attention on tonightâs rare super blood moon lunar eclipse, you might be wondering when the next solar eclipse will occur. A solar eclipse occurs when the moon passes between the Earth and the sun, blocking out all or a portion of the sun. The lunar eclipse occurring tonight is when the Earth passes between the moon and the sun, and the Earthâs shadow blocks out part or all of the moon (all of it will be blocked tonight because it is a total eclipse). According to NASA, the next solar eclipse will occur on March 9, 2016.
