#LUNAR ECLIPSE 2021 FULL#

While the lunar eclipse can be observed with the unaided eye, a pair of binoculars or a telescope can enhance the view. No special eye protection is needed for viewing a lunar eclipse, unlike solar eclipses (which occur during the daytime). As NASA works to establish a permanent human presence on the Moon through the Artemis program, it’s fascinating to consider how Earthlings will experience astronomical events away from their home planet. The degree of redness of a fully eclipsed Moon can be influenced by atmospheric conditions resulting from volcanic eruptions, fires, and dust storms.īut what does Earth look like from the Moon’s perspective during a lunar eclipse? According to Mitzi Adams, astrophysicist at Marshall, astronauts on the Moon during a total lunar eclipse would see a red ring around a silhouetted Earth.

Some of that red light is refracted, or bent, as it passes through Earth’s atmosphere and ends up shining on the Moon with a ghostly red light. Light from the Sun collides into the gases of Earth’s atmosphere and because of its shorter wavelength, blue light is filtered out, but red light is not easily scattered because of its longer wavelength. Rayleigh scattering is also the reason for red sunrises and sunsets. Credit: NASA’s Scientific Visualization Studio The map is centered on 168★7’W, the sublunar longitude at mid-eclipse. Contours mark the edge of the visibility region at eclipse contact times. The scattering is a phenomenon called Rayleigh scattering – named after the 19th-century British Physicist Lord Rayleigh.Ī map showing where the November 8, 2022, lunar eclipse is visible. The red color occurs because of the refraction, filtering, and scattering of light by Earth’s atmosphere. Those in the eastern part of the United States will miss most or all of the last partial phase because the Moon will set during totality or shortly after totality ends.Īnother feature of a total lunar eclipse is the Moon’s red hue during totality. Then, the partial phase will resume, lasting until 6:49 a.m. CST, with totality beginning at 4:16 a.m. The partial eclipse will begin at 3:09 a.m. Credit: NASA/Michoud Assembly Facilityįor North America, the action will start in the early hours of the morning on November 8. The 97% eclipse clocked in at 3 hours, 28 minutes, and 24 seconds, making it the longest partial lunar eclipse in 580 years.
