[00:03.72]The longest lunar eclipse of the century will happen late Friday
[00:09.44]or early Saturday, depending on where you live.
[00:14.52]The American space agency NASA
[00:17.60]says the moon will move into the Earth's shadow on Friday night.
[00:23.24]For four hours, it will be partly in the Earth's shadow.
[00:28.00]The total eclipse will last 1 hour 42 minutes and 57 seconds.
[00:37.24]The eclipse will be visible to people in Europe, Africa
[00:42.12]and the Middle East on July 27 between sunset and midnight.
[00:49.76]Those who live in Asia and Australia will be able to see the eclipse
[00:55.36]between midnight and sunrise on July 28.
[01:01.08]The eclipse will turn the light color of the moon to deep red.
[01:06.96]Scientists call this kind of moon a "blood moon."
[01:12.36]Andrew Fabian is with the University of Cambridge.
[01:17.04]He spoke with the Reuters news agency.
[01:20.80]"It's called a blood moon because the light from the sun
[01:25.06]goes through the Earth's atmosphere on its way to the moon
[01:30.40]and the Earth's atmosphere turns it red in the same way
[01:35.60]that when the sun goes down, it goes red."
[01:39.58]Unlike a solar eclipse,
[01:42.00]people can look at a lunar eclipse directly with their own eyes.
[01:48.12]On the same day as the eclipse,
[01:50.88]the planet Mars will be at its brightest as it travels close to Earth.
[01:57.92]The eclipse, however, will not be visible from North America or most of the Pacific.
[02:05.80]The next lunar eclipse of such length will happen in 2123.
