Lunar eclipses occur when Earth aligns between the sun and the moon and casts a shadow across the lunar surface. A lunar eclipse only happens during a full moon and can last as long as six hours, according to the European Space Agency (ESA)
Weather permitting, the best view will be Sunday night (5/15) from about 9:30 p.m. until 11:00 p.m. during totality, with 100% of the Moon turning a dark red color as it passes through the Earth’s shadow.
Total lunar eclipses occur when the whole moon passes through the innermost part of Earth’s shadow — the umbra. During a total eclipse, the Earth blocks all direct sunlight from reaching the lunar surface. Instead, sunlight scattered by Earth’s atmosphere is reflected off the moon’s surface, giving it its copper hue. This type of lunar eclipse is known as a “blood moon” due to its striking red appearance.
This will be the first of two lunar eclipses in 2022. The next one will take place on Nov. 8, 2022. It will be visible at least partially from Asia, Australia, North America, parts of northern and eastern Europe, the Arctic, and most of South America, according to TimeandDate.com.
