Lunar Eclipse

What is a Lunar Eclipse?

The Moon must be in the full moon phase for the eclipse to occur fully. A complete lunar eclipse can occur only when the Sun, Earth, and Moon are in the same plane.

Since the Moon’s orbit around the Earth lies in a plane slightly different from the Earth’s orbit of the Sun, perfect alignment for an eclipse does not occur on every full moon. A full Lunar eclipse develops for several hours. Earth casts two shadows that fall on the Moon at the time of the lunar eclipse. The first one is the umbra is a full dark shade. The second, the penumbra, is a partial outer shade. The moon passes through these shadows gradually. In the beginning and ending phases, namely, when the Moon is in the penumbral shadow, the eclipse is not so pronounced. The best part of the eclipse occurs in the middle of the event when the Moon is in the umbral shadow.
A total lunar eclipse is an image that occurs when the full shadow of the Earth falls on the Moon. The Moon becomes completely dark, and if you are not looking at the sky for a Lunar eclipse, you may think that the Moon has not appeared. Sometimes, when the sun’s rays enter the Earth’s atmosphere, they are refracted due to different intensities. These refracted Sun rays can be reflected on the Moon’s surface, thus turning a red color instead of being total darkness.
Partial Lunar eclipses, some eclipses are only partial. But even a complete Lunar eclipse goes through a partial phase on either side of the total. During the partial phase, the Sun, Earth, and Moon are not perfectly aligned, and the Earth’s shadow falls on the Moon’s surface, partially obstructing the Moon’s view.

The semi-shadow lunar eclipse is the most interesting type of Lunar eclipse. Because the Moon is in the pale shadow of the Earth. If you are not an experienced observer, you may have difficulty noticing this and think that there is no difference in the appearance of the Moon.
