The world will on Friday experience a rare spectacle of the longest lunar eclipse in the 21st century.
The eclipse will last for about four hours and will be visible across Europe, Asia, Africa, South America, Middle East and Australia.
The total eclipse, where the earth will be plunged in total darkness when the earth's shadow completely covers the moon, will last for about one hour and 43 minutes.
The totality in Nairobi will begin at 10:30 pm while viewers in cities like Cairo in Egypt will see it at 9:30 pm.
Partial eclipse, where the moon will be partly covered, will last for 3 hours and 54 minutes.
This will be the first central lunar eclipse since June 15, 2011.
A partial solar eclipse occurred on July 13, 2018.
Part of the Moon's shadow fell near the South Pole, so partial coverage of the Sun was visible in parts of southern Australia.
The eclipse was also visible in Stewart Island in the far south of New Zealand.
Unlike a solar eclipse, a lunar eclipse is safe to watch with the naked eye; you're only looking at the Moon, at night, which is quite safe.
A solar eclipse is potentially dangerous because viewing a solar eclipse involves looking at the Sun, which can damage your eyesight.
The next total lunar eclipse after the one on Friday will take place on January 21 next year.
Other incidences of central lunar eclipses will occur in January 2084, May 2087, September 2090,
June 2094, and April 2099.
Obviously, none of the those who will witness Friday's and next year's spectacle will be alive to see it happen.
