Wednesday's rare total lunar eclipse promises to be 100 minutes long. The full event can be seen from from the eastern half of Africa, the Middle East, central Asia and western Australia, according to NASA. Parts of it will be seen in Europe, Asia, and Australia.
None of it can be seen in North America. Viewers, however, can watch a live webcast here, which starts at 18:33 GMT.
A lunar eclipse of Wednesday's duration is rare. The last time a comparable one occurred was in July 2000. The next time something like that will occur is in July 2018.
During total lunar eclipses, the earth blocks the moon from direct sunlight with the narrow and dark part of its shadow (called the umbra). The indirect sunlight that will hit the moon, distorted by the earth's atmosphere, will be beautiful shades of orange and red.
Normally, the directly and undistorted sunlight that hits the moon looks white.
