A blood moon - and the longest lunar eclipse of the 21st century - will occur on the night of June 27 and the morning of June 28. The second of the year will appear on the intermediary night of July 27-28, as per reports.
"The blood moon is the result of a total lunar eclipse, which is when the moon passes directly behind earth and into its shadow". Europe and Africa will witness the eclipse during the evening hours. The longest that a lunar eclipse could ever occur is one hour and 47 minutes.
Despite its ominous name, a blood moon is just another way to describe a lunar eclipse in which the Moon passes behind Earth and travels into its shadow. This also outstrips the Super Blue Blood Moon combination that occurred in January of this year by almost three-quarters of an hour. McClure estimates that the total lunar eclipse will include partial eclipses that start at 6:24 UTC, or 2:24 p.m. EST, to 10:29 UTC, or 6:29 p.m. EST.
The moon, once again, will threaten to end humanity next month by turning the color of blood and then going dramatically, and completely, dark.
Recent red skies are apparently down to the specific scattering of light particles through the atmosphere. Rather than the moon disappearing from view, as happens in a solar eclipse, skywatchers can expect to see it turn a rather sinister shade of crimson, which is why many call it a "blood moon". This freakish phenomenon is known as "Rayleigh scattering" filters out bands of green and violet light in the atmosphere during an eclipse.
The eclipse will be visible only from the Eastern hemisphere - Europe, Asia, Australia and New Zealand.The last longest eclipse took place on July 16, 2000, and lasted for one hour and 46.4 minutes. The last lunar eclipse, which took place on January 31, lasted for an hour and 17 minutes. Meanwhile, only parts of South America will get to witness the final stages of the eclipse, and North America, the Arctic, and numerous fish in the Pacific Ocean won't get to see it at all.
