Eclipse 2018: What is the term Super blue blood moon?

Almost 152 years later, the trifecta celestial event dubbed as the Super Blue Blood Moon will occur again just before sunrise January 31, 2018. BLOOD because of the reddish hue cast during the eclipse when the Earth moves between the moon and the sun. As the earth's shadow begins to obscure the moon, it may turn a shade or hint of red. This is a combination of three celestial phenomenon, a supermoon, a blue moon, and a lunar eclipse.

But unfortunately for the United Kingdom, much of the spectacle won't be visible from our shores, because the eclipse is taking place at about 1pm when it's daylight. The farther west you live, the more of the eclipse you'll see.

This proximity, or perigee, makes it appear 14 percent bigger than normal and 30 percent brighter. The moon will leave the umbra at 7:11 a.m. PST.

The eclipse will enter its total phase after the moon has set along the East Coast of the U.S.

The timing of the peak of the eclipse is at 8:29 a.m. ET, however it will be cut short for anywhere east the Mississippi River, due to when the Moon sets. When a full moon occurs twice in one month, the second one is called a blue moon. It says a blue moon was more traditionally the third full moon in a season when there were four of them, instead of the usual three. The lunar eclipse would end at 7:37 pm.

People in eastern Russia, Middle East, Asia, Australia, and New Zealand will also get a chance to see the lunar eclipse during January 31's moonrise. The original definition is the third Full Moon in an astronomical season that has four Full Moons. This is caused by the earth's atmosphere bending red light into the planet's shadow while scattering the blue wavelengths.

NASA's Ames Research Center is working on plans to send a rover to one of the moon's poles - previous missions have targeted areas near the equator. "The blue moon has nothing to do with the color and has only to do with the calendar, and blood moon is not always an apt description - it's not always blood red".

The world is about to witness a "super blue blood moon" on Wednesday morning, the first since September 2015. This month we are book ended by full moons, we started 2018 with one and we end the month with another. Commonly nowadays when that happens the event is referred to as a blue moon, although Space.com reckons that's not technically quite right.
