Blood Moon to bring the longest lunar eclipse in a century

Blood Moon

Blood Moon

A lunar eclipse, commonly referred to as a "blood moon", graces the night sky.

The total eclipse is set to last for 1 hour and 43 minutes. This also outstrips the Super Blue Blood Moon combination that occurred in January of this year by almost three-quarters of an hour. That's just a few minutes shorter than the maximum possible eclipse, and the length of an average movie, for those who'd rather get outside and look at the skies, rather than stare at a screen indoors. Europe and Africa will witness the eclipse during the evening hours, sometime between sunset and midnight on July 27, according to the reports.

The next total lunar eclipse on January 21, 2019, will last 1 hour and 2 minutes.

"Sometimes called an apogean full moon, or micro-moon or mini-moon, this smaller and slower-moving full moon takes more time to cross the Earth's shadow than does a full moon that's closer to Earth and moving faster in orbit", McClure said.

For those that may not be in the know, a blood moon is a very rare astronomical phenomenon that takes place because of a lunar eclipse, which happens when the earth comes in line between the sun and the moon.

Doomsday preachers have been reportedly suggesting that July's blood moon heralds the end of the world, as biblical passages talk about the moon turning the colour of blood prior to the apocalypse - and we have had several such events recently. It will turn blood red during the eclipse due to the way light bends around Earth's atmosphere. The last lunar eclipse, which took place on January 31, lasted for an hour and 17 minutes. This weird phenomenon is known as "Rayleigh scattering" filters out bands of green and violet light in the atmosphere during an eclipse.

The eclipse won't be visible to viewers in North America, except via webcasts.

On the night of July 27 and the early morning hours of July 28, skywatchers in the Eastern Hemisphere will be treated to the longest lunar eclipse set to occur in the 21st century, EarthSky reports.
