This weekend, the moon will plunge into total darkness, creating a celestial spectacle not seen in a while. From Sunday night to Monday morning, there will be a total lunar eclipse — the first of 2022. The total lunar eclipse will be visible from parts of South and North America, Antarctica, Europe, Africa and the eastern Pacific. A total lunar eclipse is sometimes called a “blood moon” because the moon appears dark red at the peak of the eclipse. However, this weekend’s total lunar eclipse will not be visible in India.
A lunar eclipse occurs when the Sun, Earth, and Moon are all aligned, causing the Moon to fall into Earth’s shadow. During a total lunar eclipse, the entire moon is engulfed by the darkest part of Earth’s shadow, called the umbra.
While the eclipse will not be visible from India, those interested can watch the event live on NASA. From May 15th at 11pm ET to May 16th at 12am ET, which is 8.33am EST on Monday (May 16th), the space agency will broadcast the solar eclipse live and experts will Comment on each step of the process.
You can watch the live stream here:
The eclipse will last over five hours, starting at 9:32pm EST on Sunday, May 15 (7.02am EST on Monday) and ending at 2:50am EST (7.02am EST on Monday), May 16 16 May at 12.20pm).
During a total eclipse, the blood moon can vary in color from a bright saffron-yellow disc with blue limbs to a dark brick red. The Moon is known to all but disappear from view during a total eclipse, as happened during the December 1992 lunar eclipse, shortly after the eruption of Mount Pinatubo in the Philippines.
The Danjon Scale ranges from 4 (bright) to 0 (dark) and is used to describe the color and intensity of the moon during its overall (dark) period.
Another unusual sight to look for during a total lunar eclipse is the elusive selenium, or seeing a completely eclipsed moon and a rising sun above the horizon at the same time. This is because Earth’s umbra is larger than the Moon’s, and Earth’s atmosphere refracts light from both.
