- Dark red or brown coloration of the moon during a total Eclipse because the sun's rays passing through the upper layers of earth's atmosphere, refracted.
The Blood Moon is an occurrence where sunlight causes the eclipsing sun to appear red in colour. It is going to be the longest eclipse of the 21st century Although it is expected to last 103 minutes, those in the United Kingdom and Ireland will not be able to see the start of the lunar eclipse as the moon will still be below the horizon.
In total, the full lunar eclipse will last one hour and 42 minutes, the longest it will be this century.
The moon also moves slower when it is farthest from Earth.
The best view will be in Africa and Asia, however people in Europe, South America, and Australia will be able to witness partially.
In the evening of July 27, 2018, the Moon will take on a splendid red brick color during a total eclipse.
Thai PBS reports that the total phase of the eclipse - called the totality, when the earth blocks out all light from the sun falling on the moon - will span 1 hour and 43 minutes.
According to a release by ASSA, "The moon will start changing shape as it enters the shadow of the Earth at 20h24". This phenomenon will also take place alongside the Blood Moon. Mars is also safe to view with the naked eye.
Some Christians believe the celestial event could mark the start of disaster, based on a passage from the biblical Book of Joel, which reads: "The sun shall be turned into darkness, and the moon into blood, before the great and the bad day of the Lord comes". In a lunar eclipse, the roles reverse and the Earth casts a shadow on the moon.
"You get a true sense of the solar system moving - and that in itself is a really dramatic experience".
The eclipse will reach maximum totality at 9.21pm and finish at 10.31pm, though the partial eclipse will continue for another two hours after that.
The Virtual Telescope Project will share a live stream of the lunar eclipse and Mars at its brightest just a few degrees apart above the skyline of Rome. "Star-gazers in areas near the Middle East, south or eastern Africa, western and southeast Asia and India will be able to catch a glimpse of the celestial event as long as the weather permits".
