Question

What is meant by the eclipse of the moon?

Answer 1

Hint:When the sun, the earth, and the moon all line up in a straight line, an eclipse occurs. There are two types:
Lunar Eclipse: The Moon passes through the shadow of the Earth. On a full moon day, it always happens. A total lunar eclipse occurs when the moon is fully obscured by the earth's shadow, whereas a partial lunar eclipse occurs when the moon is partially obscured by the earth's shadow.

Complete step-by-step solution:
When the Moon passes through the shadow of the Earth, a lunar eclipse occurs. This can only happen on the night of a full moon when the Sun, Earth, and Moon are precisely or extremely closely aligned (in syzygy), with Earth between the other two. The kind and duration of a lunar eclipse are determined by the Moon's closeness to one of its orbital nodes. The crimson tint of a completely eclipsed Moon, which is caused by Earth entirely obstructing direct sunlight from reaching the Moon, is frequently referred to as a blood moon. Earth's atmosphere has refracted the only light reflected from the lunar surface. The Rayleigh scattering of blue light causes this light to seem reddish, much as it does at sunset or dawn. A lunar eclipse may be seen from a place on Earth's night side, unlike a solar eclipse, which can only be seen from a restricted section of the globe. Because the Moon's shadow is narrower, a complete lunar eclipse may last up to nearly 2 hours, but a complete solar eclipse can only last a few minutes at any one location. Lunar eclipses, unlike solar eclipses, may be viewed without eye protection or extra precautions since they are fainter than the full Moon.

Note:The umbra and penumbra are the two separate regions of the Earth's shadow. Within the umbra, the centre portion of the shadow, the Earth completely blocks direct sunlight. However, because the Sun's diameter in the lunar sky is only a fourth of Earth's, the planet only partially shields direct sunlight within the penumbra, the shadow's outer component.
