This Friday you may witness longest lunar eclipse of century. But not in U.S.Staff Writer | July 23, 2018
This week promises to be a special one, for it will be the longest-lasting total lunar eclipse of the 21st century.
Space The time of greatest eclipse will be 2021 GMT on July 27
The "blood moon" eclipse, which takes its name from the red hue the moon takes on, will last four hours from start to finish, with the entire celestial event lasting nearly four hours.
A lunar eclipse occurs when the path of the Earth's orbit lines up directly between the sun and the moon. When this happens, the Earth blocks the light from the moon, darkening the moon with the Earth's shadow.
If the sun's rays are completely blocked, the moon takes on a ruddy red or burnt orange hue, giving it the name "Blood Moon."
The disappointing news for those in North America is the lunar eclipse won't be visible except online. To get a view of the eclipse, you would have to travel to Africa, the Middle East, southern Asia or the Indian Ocean area.
According to space.com, the eclipse will be visible from eastern South America as it is ending and from Australia as it is beginning.
The time of greatest eclipse will be 2021 GMT on July 27, according to EarthSky.org. The total eclipse will last from 1930 to 2113 GMT.
There will also be some time before and after when the moon is in the lighter part of Earth's shadow, which is called the penumbra. Including that penumbral time, the eclipse will last for 3 hours and 55 minutes. ■
