New Delhi, Nov 16: The world would witness the longest partial lunar eclipse in 580 years on November (19). The rare phenomenon will be visible in parts of Asia, including India, North America, South America and Europe.
A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow.
On November 19, 2021, the Moon passes into the shadow of the Earth, creating a partial lunar eclipse so deep that it can reasonably be called almost total.
‘A partial lunar eclipse is on the way, taking place overnight on 18 and 19 November, when the Moon slips into Earth’s shadow for a couple of hours. Weather permitting, the eclipse will be visible from any location where the Moon appears above the horizon during the eclipse,’ Space agency NASA said.
Is it a ‘Blood Moon’ eclipse?
During November 19 partial lunar eclipse, the moon is likely to appear blood-red in colour because the only sunlight reaching the Moon passes through Earth’s atmosphere.
“The more dust or clouds in Earth’s atmosphere during the eclipse, the redder the Moon will appear,” according to NASA.
