What is a lunar eclipse?
A lunar eclipse occurs when Earth comes in between the Moon and the Sun. While a total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth, a partial lunar eclipse happens when only part of Earth’s shadow covers the Moon. Meanwhile, when the Moon travels through the faint penumbral portion of Earth’s shadow, a penumbral lunar eclipse happens.
The partial Lunar eclipse will be visible from North America, South America, eastern Asia, Australia, and the Pacific region.
What will happen on November 19 lunar eclipse
The moon is likely to appear blood-red in color, which happens when the red beams of the sunlight pass through the Earth’s atmosphere and get least deflected and fall on the moon.
The last time a partial lunar eclipse of such length occurred was on February 18, 1440, and the next time a similar phenomenon can be witnessed will be on 8 February 2669.
