The Chicago area and much of North America will experience a total lunar eclipse on Sunday, May 15, according to the Adler Planetarium. Weather permitting, Chicagoans will be able to view the eclipse beginning at 8:32 p.m.
The peak of the event will be between 10:30 pm and midnight, with the eclipse ending at 1:50 am on May 16.
During a lunar eclipse, according to an announcement from Adler on Monday, the Earth comes between the Sun and the Moon, blocking direct sunlight and casting shadows on the Moon. The Moon will appear to turn a red, orange, or gray color.
A total lunar eclipse occurs about once every two and a half years.
According to a NASA website, the color red comes from the way the Earth’s atmosphere scatters light waves. During a lunar eclipse, the Moon turns red because the only sunlight that reaches the Moon passes through our atmosphere and is scattered by dust and clouds, just like during a sunset.
The Adler will host a free outdoor lunar eclipse viewing event on May 15, from 9 pm to midnight, weather permitting. Telescopes will be available for guest use, and Adler staff will be available to answer questions. Free reservations are required at tickets.adlerplanetarium.org.
This eclipse will be visible from North and South America, Europe, Africa and parts of Asia, according to Space.com, and will follow a second total lunar eclipse of 2022 on November 8, visible at least partially from Asia, Australia, North America. , parts of Europe and most of South America.
NASA maintains a list that predicts lunar eclipses up to 2100.
