when is the next solar eclipse 2022

The next solar eclipse is set to occur on April 30, 2022. This celestial event will be an annular solar eclipse, also known as a “ring of fire” eclipse. It will be visible from parts of South America, including Chile and Argentina, as well as from the southernmost regions of Africa. During an annular eclipse, the Moon passes directly in front of the Sun, but its apparent size is slightly smaller, creating a ring-like effect. It is a rare and captivating phenomenon that attracts skywatchers and astronomers alike, offering a unique opportunity to witness the wonders of our solar system.

How long will blood moon last?
During a total lunar eclipse, the full Moon moves through Earth’s shadow in space, which spans a distance of 870,000 miles (14 million km). These occurrences are rare and can vary in duration, ranging from 105 minutes in 2018 to just five minutes in 2015.

On November 8, 2022, in the early hours, a total lunar eclipse will take place, lasting for 85 minutes. This eclipse will traverse the northern part of Earth’s shadow, near its edge. As a result, the northern region of the eclipsed Moon is expected to remain relatively bright during totality. This is in contrast to the deep, dark, and awe-inspiring Blood Moon observed from North America in May of last year.

What eclipse is very rare?

On April 20, a rare celestial event will occur as the Moon passes between the Sun and Earth, creating a total solar eclipse. This eclipse will be visible from Exmouth, a town in Western Australia. It is a hybrid eclipse, meaning it will shift between a total and annular eclipse depending on the observer’s location on the ground. Hybrid eclipses are rare and only occur a few times a century. Out of the 224 solar eclipses in the 21st century, only seven will be hybrid. After this event, the next hybrid eclipse will not occur until 2031. The eclipse will begin at 9:36 pm Eastern time and will first be visible in the Indian Ocean before moving across to the Pacific Ocean. The best views of the eclipse will be for those in Western Australia, East Timor, and eastern Indonesian islands. In Timor, the moon will completely cover the sun for over one minute at 12:16 am Eastern time. The hybrid eclipse will end at 2:59 am Eastern time on April 20.

What are the 3 eclipses?

Solar eclipses come in four different types: total, partial, hybrid, and annular. The specific type of eclipse that can be observed depends on the alignment of the Moon, Earth, and the Sun, as well as the distance between the Moon and Earth.

On the other hand, lunar eclipses can be categorized into three types: total, partial, and penumbral. While partial lunar eclipses occur at least twice a year, total lunar eclipses are quite rare. Unlike solar eclipses, it is always safe to directly observe a lunar eclipse without any protective eyewear.

To gain a deeper understanding of these celestial phenomena, it is recommended to explore further information on the three types of eclipses. In the accompanying image, a side-by-side comparison showcases a total solar eclipse, an annular solar eclipse, and a partial solar eclipse. It is worth noting that a hybrid eclipse can appear as either a total or annular eclipse, depending on the location of the viewer.

When was last blood moon?

When was last blood moon?
A blood moon occurs during a total lunar eclipse when the Earth’s moon appears red or ruddy brown. This phenomenon occurs when the Earth passes between the moon and the sun, blocking the sunlight and causing an eclipse. The last blood moon occurred on November 8, 2022, and the next one will happen on March 13-14, 2025.

During a partial eclipse, the sun is partially blocked by the Earth, creating a black shadow on the moon’s surface. In a penumbral eclipse, the moon passes through the lighter part of the Earth’s shadow, causing a slight darkening of the moon. Only experienced skywatchers can distinguish between the two.

However, during a full eclipse, the moon is fully in Earth’s shadow, and a phenomenon known as “earthshine” occurs. This happens when a small amount of light from Earth’s sunrises and sunsets reflects off the planet and onto the moon’s surface. The stretched-out light waves appear red, giving the moon its red color during a blood moon.

The intensity of the red color can vary depending on atmospheric conditions such as pollution, cloud cover, and debris. For example, after a volcanic eruption, the particles in the atmosphere can make the moon appear darker than usual.

Lunar eclipses are unique to Earth because our planet’s shadow is just large enough to completely cover the moon. However, the moon is slowly moving away from Earth at a rate of about 16 inches or 4 centimeters per year. This means that the frequency of lunar eclipses will decrease over time. NASA estimates that there are typically two to four lunar eclipses each year, and they are visible from about half of the Earth.

Why is blood moon red?

The Moon turns red during a lunar eclipse due to a phenomenon called Rayleigh scattering. This is the same phenomenon that causes our sky to appear blue and our sunsets to appear red. Rayleigh scattering occurs because different colors of light have different physical properties. Blue light, which has a shorter wavelength, is scattered more easily by particles in Earth’s atmosphere compared to red light, which has a longer wavelength.

When sunlight passes above and below Earth’s atmosphere, it is broken up into a rainbow spectrum, with the red parts of the spectrum falling on the Moon. During a lunar eclipse, Earth’s atmosphere scatters sunlight, causing the blue light from the Sun to scatter away. This allows longer-wavelength red, orange, and yellow light to pass through and reach the Moon, giving it a red appearance.

On the other hand, red light travels more directly through the atmosphere. When the Sun is overhead, we see blue light throughout the sky. However, when the Sun is setting, sunlight must pass through more atmosphere and travel a greater distance before reaching our eyes. This causes the blue light from the Sun to scatter away, allowing longer-wavelength red, orange, and yellow light to pass through and create the beautiful colors we see during a sunset.

During a lunar eclipse, the Moon turns red because the only sunlight reaching it has passed through Earth’s atmosphere. The amount of dust or clouds in Earth’s atmosphere during the eclipse can affect the intensity of the red color observed on the Moon. In a way, it is as if all the world’s sunrises and sunsets are projected onto the Moon, creating a stunning visual display.

In conclusion, the red color of the Moon during a lunar eclipse is a result of Rayleigh scattering and the scattering of blue light by Earth’s atmosphere. This phenomenon allows longer-wavelength red, orange, and yellow light to reach the Moon, giving it a reddish hue. The intensity of the red color can vary depending on the amount of dust or clouds in Earth’s atmosphere during the eclipse.

Do eclipses repeat every 18 years?

The Saros cycle, which lasts approximately 65853 days, 18 years, 11 days, and 8 hours, governs the periodicity and recurrence of eclipses. This cycle was known to the Chaldeans as a period when lunar eclipses seemed to repeat themselves, but it is also applicable to solar eclipses.

The Saros cycle is derived from the harmony between three of the Moon’s orbital periods: the synodic month, the anomalistic month, and the draconic month. One Saros is equal to 223 synodic months, 239 anomalistic months, and 242 draconic months.

Eclipses that occur within one Saros cycle share similar geometries. They happen at the same node, with the Moon at nearly the same distance from Earth, and at the same time of year. However, due to the Saros period not being a whole number of days, subsequent eclipses are visible from different parts of the globe. The extra 13-day displacement means that Earth must rotate an additional 8 hours or 120º with each cycle. This results in the shifting of each successive solar eclipse path by 120º westward. Therefore, a Saros series returns to approximately the same geographic region every 3 saroses, which is equivalent to 54 years and 34 days.

A Saros series does not last indefinitely because the three lunar months are not perfectly synchronized with each other. The Moon’s node shifts eastward by about 0.5º with each cycle. A typical Saros series for a solar eclipse begins when the new Moon occurs 18º east of a node. Over the course of about 200 years, after ten or eleven Saros cycles, the first central eclipse will occur near the south pole of Earth. Over the next 950 years, a central eclipse will occur every 180.31 years (one Saros), but it will be displaced northward by an average of 300 km. Halfway through this period, eclipses of long duration will occur near the equator. The last central eclipse of the series occurs near the north pole. The next approximately ten eclipses will be partial, with successively smaller magnitudes. Finally, the Saros series will end a dozen or more centuries after it began at the opposite pole. The exact duration and number of eclipses in a complete Saros series vary due to the ellipticity of the orbits of Earth and the Moon. A series may last from 1226 to 1550 years and consist of 69 to 87 eclipses, of which about 40 to 60 are central (total, hybrid, or annular).

Solar eclipses that occur near the Moon’s ascending node have odd Saros numbers, while those occurring near the descending node have even Saros numbers. Each succeeding eclipse in a series shifts progressively southward or northward with respect to the center of Earth, depending on the node.

The Saros series is numbered using a system introduced by Dutch Astronomer G. van den Bergh in his book “Periodicity and Variation of Solar and Lunar Eclipses” in 1955. All 8000 solar eclipses in von Oppolzer’s “Canon der Finsternisse” from 1887 were placed in a two-dimensional matrix. Each Saros series was arranged as a separate column with the eclipses in chronological order. The Saros series columns were staggered so that the interval between any two eclipses in adjacent columns was 10571.95 days (29 years, 20 days), which is another important eclipse cycle called the Inex. This resulted in the Saros-Inex Panorama, which proved useful in organizing eclipses. Each step down in the panorama represents a change of one Saros period, while each step to the right represents a change of one Inex period. The rows and columns of the panorama were then numbered with the Saros and Inex numbers.

It is important to note that the Saros numbering sequence does not depend on when a series begins or ends. Generally, the numbering follows the order in which each series peaks. The peak of a series occurs when the umbral shadow axis passes closest to the center of Earth. Since the duration of each series varies and the numbering approximately follows the order of each series’ peak, it is possible for the first eclipse of a series that peaks later to precede the first eclipse of a series that peaks earlier.



In conclusion, lunar eclipses are relatively rare celestial events that captivate the attention and curiosity of people around the world. While eclipses do not repeat exactly every 18 years, there is a pattern known as the Saros cycle that occurs approximately every 18 years and 11 days, resulting in a similar alignment of the Sun, Earth, and Moon. This cycle allows for the occurrence of three different types of eclipses: total, partial, and penumbral.

Among these three types, the rarest eclipse is considered to be the total lunar eclipse. This phenomenon happens when the Earth completely blocks the Sun’s light from reaching the Moon, resulting in a stunning display of a fully eclipsed Moon. The total lunar eclipse is often referred to as the “blood moon” due to the reddish hue that the Moon takes on during this event. This occurs because the Earth’s atmosphere scatters shorter wavelengths of light, allowing longer wavelengths, such as red and orange, to reach the Moon.

The last blood moon occurred on May 26, 2021, and lasted for approximately 14 minutes. However, the duration of a lunar eclipse can vary, with some lasting for a few minutes to several hours. The upcoming lunar eclipse in 2023 is expected to be a total eclipse, providing a rare opportunity for skywatchers to witness this captivating event.

While the 2023 eclipse will be total, it is important to note that not all eclipses are total. Some eclipses may be partial or penumbral, where only a portion of the Moon is obscured or the Moon passes through the Earth’s outer shadow. Therefore, the rarest eclipse in 2023 would be the total lunar eclipse.

Overall, the rarity and beauty of lunar eclipses continue to fascinate and inspire people worldwide. Whether it is the mesmerizing sight of a blood moon or the anticipation of witnessing a total eclipse, these celestial events serve as a reminder of the vastness and wonder of our universe.
