Shalom, everyone! The following is video from National Geographic called “Lunar Eclipse 101,” which provides an overview of how lunar eclipses occur, the types of lunar eclipses (total lunar eclipse, partial lunar eclipse, and penumbral lunar eclipse), and how the moon gains a red color during a total lunar eclipse. Total lunar eclipses are visible to the naked eye; there is no need to take the same safety precautions that are necessary when viewing a solar eclipse. This next total lunar eclipse, a blood moon, occurs on Friday, July 27, 2018 beginning at 4:20 PM in the Northern Hemisphere, and will be completely visible over Eastern Africa and Central Asia, rising over South America, Western Africa, and Europe, and setting over Eastern Asia, and Australia. This will lunar eclipse be the longest total lunar eclipse of the 21st century with totality lasting approximately 103 minutes. This total lunar eclipse will also mark Keseh Karar, the full moon of the Fifth Month on the ecclesiastical Hebrew calendar.
Nicknamed “blood moon,” some ancient cultures regarded a total lunar eclipse as an ominous event. Today, this celestial phenomenon generates excitement and wonder. Unlike a solar eclipse, which may require travel to see, total lunar eclipses can often be observed from the entire nighttime-half of the Earth. Learn what causes a lunar eclipse and how it gains its crimson coloring.
