TOTAL LUNAR ECLIPSE TO OCCUR ON WEDNESDAY,8TH OCTOBER,2014


Early risers across much of the world are in for a treat on Wednesday morning – a total lunar eclipse, also known as a “blood moon” due to the coppery, reddish colour the moon takes as it passes into Earth’s shadow.
The total eclipse is the second of four over a two-year period that began on 15 April and concludes on 28 September 2015. The so-called tetrad is unusual because the full eclipses are visible in all or parts of the United States, according to the retired Nasa astrophysicist Fred Espenak.
Weather permitting, Wednesday’s eclipse should be visible to skywatchers in North America, Australia, western South America and parts of East Asia. The eclipse should reach totality just before sunrise, at 6.25 am EDT (1025 GMT).


An eclipse occurs when the moon passes through Earth’s shadow, called the umbra. As for the reddish hue, Tony Phillips, an astronomer with SpaceWeather.com, says to imagine yourself on the moon: “Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is under way. You might expect Earth to be utterly dark, but ... the rim of the planet is on fire.”
“You’re seeing every sunrise and every sunset in the world, all at once,” Phillips wrote in an article on Nasa’s science website.
The light beams into Earth’s shadow, filling it with a coppery glow that colours the moon red, he said.
The entire eclipse will be visible from the Pacific Ocean, regions immediately bordering it and the north-western section of North America. Farther east, the later phases of the eclipse occur after moonset. The eclipse will not be visible from Europe, Africa and the Middle East, Nasa said.
