The moon will transform into a blood red hue this Friday night, July 27, during the longest lunar eclipse of the 21st century.
People around the world, except in North America, will be able to catch at least some of the celestial sight. On the same day, Mars will appear at its brightest directly below the moon.
What is a Blood Moon?
Traditionally, astronomers don’t use the term, but ‘blood moon’ has come to refer to the deep red hue of the moon during a total eclipse.When light from the sun passes through the earth’s atmosphere to the moon, the earth’s atmosphere turns the moon red, in the same way the sun turns the sky red during a sunset, according to Andrew Fabian, professor of astronomy at the University of Cambridge.
When the moon moves into the conical shaped shadow of the earth, it goes from being illuminated by the sun to being dark. Some light, though, will still reach the moon because it is bent by the earth’s atmosphere.
“If you were standing on the moon in this eclipse, you would see the sun and then the earth would come in the way and blot out the sun,” said Fabian. “The rim of the earth would be glowing because light is being scattered by the earth’s atmosphere.”
When can you see it?
The blood moon will be visible in Australia, Asia, Africa, Europe, and South America, as long as the skies are clear. A partial eclipse will proceed and follow the total eclipse.-In the UK, the total eclipse will take place between 9:20 p.m. and 10:13 p.m. on Friday night -In Africa, the moon will be red between 10:30 p.m. and 12:13 a.m. -In India, the moon will be red from 1 a.m. on Saturday morning until 2:43 a.m. -In Beijing, China, it will occur from 3:30 a.m. until 5:13 a.m. -In Australia, the total eclipse will occuer between 5:30 a.m. and 6:30 a.m. on Saturday morning
For those missing out on this celestial event, the next total lunar eclipse will be on Jan. 19, 2019. This one will be visible across the United States.
