All You Need To Know About Total Lunar Eclipse

A Total Lunar Eclipse Is What?

Total Lunar Eclipse – When the Earth stands between the Sun and the Moon and its shadow falls upon it, there is a total lunar eclipse. When the eclipse reaches its greatest magnitude, spectators can see the Moon become red.

Paired Together

When the Sun, Earth, and Moon are lined up during a full moon, total lunar eclipses take place. Astronomers refer to this type of alignment as syzygy, which is derived from the Greek word “conjugation.”

Earth That Blocks Sunlight

The moon doesn’t produce any light on its own, but glows because the sun’s rays are reflected off of its surface. Because the Earth is positioned between the Sun and the Moon during a complete lunar eclipse, the Moon cannot receive direct sunlight. The Moon’s surface is covered by the Earth’s shadow, which is thrown by the Sun.

Three Shadows Of The Earth

The shadow of the Earth can be divided into three parts:

  • The shadow is a darker central part.
  • Twilight: the external part.
  • Antambra is a partially shaded area outside the shadow.

During a total lunar eclipse, the shadow of the Earth completely covers the Moon.

Sun, Earth and Moon On The Same Line

A lunar eclipse only happens when the Sun, Earth, and Moon are roughly lined up. Otherwise, the Moon’s surface cannot be covered by the shadow of the Earth, and an eclipse cannot take place.

Total lunar eclipses happen when the Earth, Sun, and Moon are lined up in a straight line. A partial lunar eclipse occurs when the alignment of the three bodies causes the Moon to be partially engulfed in the Earth’s shadow. A penumbral lunar eclipse, on the other hand, happens when only the outer portion of the earth’s shadow covers the Moon.

The shadow of the Earth extends into space far beyond the orbit of the Moon. This means that the terrestrial antumbra plays no role in lunar eclipses.

  • Only with a full moon
  • Total lunar eclipses only occur when:
  • This moon is full.

The Sun, Moon, and Earth are all in a straight (or nearly straight) line because the Moon is at (or very near) the lunar node at the same time.

This is due to the fact that the ecliptic, or plane of the Earth’s orbit around the Sun, is tilted at an angle of 5 degrees with respect to the Moon’s orbital path around the planet. The term “lunar node” refers to the intersection of two orbital planes. When the full moon rises close to the lunar node, a lunar eclipse takes place.

The Moon Looks Red

Even though the Earth prevents direct sunlight from reaching the Moon’s surface during a total lunar eclipse, the Moon is still visible to the naked eye. This is because the Earth’s atmosphere refracts sunlight and indirectly illuminates the surface of the Moon.

As sunlight passes through the Earth’s atmosphere, it is refracted towards the Earth’s surface and some of the shorter wavelength colors are scattered and filtered out, while the rest of the longer wavelength colors, such as orange and red, they pass through the atmosphere. . This light is refracted back to the surface of the completely eclipsed Moon, illuminating it with a red-orange glow. For this reason, a total lunar eclipse is sometimes colloquially referred to as the Blood Moon.

Eclipses Of Different Colors

Also possible are yellow, orange, and brown lunar eclipses. This is due to the fact that various types of clouds and dust particles in the Earth’s atmosphere enable various wavelengths to reach the Moon’s surface.

Blood Moons And Tetrads

A lunar tetrad is a grouping of four consecutive total lunar eclipses without any partial or intermediate penumbral eclipses. Recent years have seen a rise in the term “blood moon” to describe eclipses that occur during the lunar tetrad. This usage of the phrase, which is said to have Biblical roots, lacks any scientific or astronomical foundation.

7 Phases Of Eclipse

A total lunar eclipse usually occurs within a few hours. The total duration can vary from a few seconds to about 100 minutes. The total lunar eclipse of July 26, 1953 had one of the longest total lunar eclipse periods of the 20th century at 100 minutes and 43 seconds.

There are 7 phases of a total lunar eclipse:

  1. A penumbral eclipse begins: it begins when the penumbra part of the earth’s shadow begins to move on the Moon. This phase is not visible to the naked eye.
  2. A partial eclipse begins: The shadow of the Earth begins to cover the Moon, making the eclipse more visible.
  3. A total eclipse begins: the shadow of the Earth completely covers the Moon and the Moon is red, brown or yellow.
  4. Maximum Eclipse: This is the midpoint of a total eclipse.
  5. The total eclipse ends: in this phase, the shadow of the Earth begins to move away from the surface of the Moon.
  6. The partial eclipse ends: the shadow of the Earth completely leaves the surface of the Moon.
  7. The penumbral eclipse ends: at this point, the eclipse ends and the Earth’s shadow is completely removed from the Moon.

Where Can You See A Total Lunar Eclipse?

Almost everyone on the night side of the Earth can see a total lunar eclipse. For this reason, most people are more likely to see a total lunar eclipse than a total solar eclipse, even though they both occur at the same intervals.

What Is A Total Lunar Eclipse That Is “Nearly Total”?

When the Sun, Earth, and Moon line up, the Moon enters the Earth’s shadow, creating a lunar eclipse. The entire moon enters the shadow, which is the deepest region of the earth’s shadow, during a total lunar eclipse. Up to 99.1% of the moon disk will be covered by the Earth’s shadow during this eclipse.

What Makes This Eclipse Last So Long?

Due to the Moon’s fast orbital motion and the almost complete eclipse, this eclipse will last for a long time.

First, the Earth is not in the center of the Moon’s orbit around the Earth, thus occasionally the Moon is closer to the Earth and occasionally farther away. The Moon’s orbital velocity changes as a result of this shift in distance. The Moon travels faster and slower the closer it gets to Earth. The Moon is currently slowly passing through the Earth’s shadow since it is almost at the furthest point in its orbit around the planet.

Second, because this eclipse is near total, the Moon spends more time in the shadow of the Earth than it would during a “partial” eclipse.
