The incredible 100 minute-long eclipse will be visible from the eastern half of Africa, the Middle East, central Asia, and western Australia, according to PCMag. Eastern Asia, eastern Australia, and New Zealand will miss the final stages of the eclipse because they occur after moonset.
“The last eclipse to exceed this duration was in July 2000,” astrophysicist Fred Espenak wrote in NASA’s eclipse guide for 2011.
Four partial solar and two total lunar eclipses are set to take place in 2011, which NASA said is “rather rare” That many eclipses in a year will only happen six times in the 21st century—in 2011, 2029, 2047, 2065, 2076, and 2094. Another eclipse will occur on Dec. 10 of this year, and will set over North America.
During a lunar eclipse, the Earth comes between the sun and the moon so that all or part of the sun's light is blocked from the moon, according to NASA.
