Of all astronomical events, solar eclipses seem to receive the most attention. People around the world are eagerly awaiting the next opportunity to observe this phenomenon. In this article we explain why solar eclipses happen, what you can see during a solar eclipse, and how to properly observe them.

What is a solar eclipse?
A solar eclipse is a natural phenomenon that occurs when The moon blocks all or part of the sunlight from reaching the Earth. This results in a partial or complete darkening of the sun’s disk, depending on the position of the moon and the location of the observer. Solar eclipses always coincide with a new moon because the moon is then between the Earth and the sun.
What happens during a solar eclipse?
During a solar eclipse, the sun, moon and earth align like this The moon’s shadow falls on certain areas of our planet’s surfacea…Create Path of the solar eclipse. Since the moon’s shadow is too small to cover the entire Earth, eclipses are only visible this way.
Types of solar eclipses
The moon’s shadow can be divided into three parts: a penumbra, an umbra and an antumbra. The type of solar eclipse we see depends on which part of the shadow falls on Earth.
Partial solar eclipse
A partial solar eclipse occurs when The moon only covers part of the sun’s disk. This happens when the sun, moon and Earth do not form a perfectly straight line and the moon only casts a partial shadow dusk. From areas within the penumbra, the sun appears as a partially covered crescent or disk.
Total solar eclipse
We observe a total solar eclipse when The moon completely blocks the view of the sun from the earth, creating a total shadow or umbra. This happens when the apparent size of the Moon is larger than that of the Sun. During a total solar eclipse, the sky becomes dark as if it were night, and the Crown (outer atmosphere) of the sun becomes visible. Because the umbra is always surrounded by penumbra, a partial solar eclipse is visible from locations just outside the orbit of totality.
Annular solar eclipse
An annular solar eclipse occurs when The moon moves between the sun and the earth while it is at apogee (the furthest point from our planet) or close to it. During an annular solar eclipse, the moon projects one antombre – a type of shadow that only exists when the light source has a larger diameter than the object casting the shadow. When the Moon is far from Earth, its angular size is too small to completely cover the sun. That’s why we see this “Ring of Fire” – a thin ring of sunlight around the dark disk of the moon. Since the antumbra is always surrounded by penumbra, a partial solar eclipse is visible from locations just outside the orbit.
Hybrid solar eclipse
A hybrid solar eclipse, also called an annular total solar eclipse, goes on its way from the ring finger to the total and vice versa. Since the Earth is round, the distance to the moon varies from place to place. As a result, some places (closer to the moon) are in the path of theumbrawhile others (further from the moon) cross theantombre. Depending on their location, observers at different points on the solar eclipse path can experience either a total solar eclipse or an annular solar eclipse. However, at least from one location, you cannot see both species at the same time. Since the umbra and antumbra are always surrounded by penumbra, a partial solar eclipse can be observed from locations just outside the path of the hybrid eclipse.
The effect of Baily’s Pearls and the diamond ring
A total solar eclipse is spectacular in itself, but there are also special astronomical effects that can be observed at the same time. Because the moon is full of craters, the edge of its surface is irregular. When the lunar disk is about to completely cover the sun, the last rays of the sun penetrate the moon’s mountains and valleys, creating a series of dots that resemble a string of pearls. Therefore the name Bailey beads – in honor of the English astronomer Francis Baily, who explained this phenomenon. The diamond ring is observed when only a “pearl” remains, resembling a brilliant diamond on a glowing ring.
How often do solar eclipses occur?
Total eclipses occur approximately every 18 months, and annular eclipses occur once every 1-2 years. Hybrid eclipses are the rarest, occurring only a few times per century, or about once per decade. By and large, the world knows Between 2 and 5 solar eclipses per year. The last time 5 eclipses occurred in the same year was in 1935 and the next time it will be in 2206.
When will the next solar eclipse take place?
The next solar eclipse will take place on October 14, 2023. This solar eclipse will be annular, crossing North America, Central America and South America. We have written a comprehensive guide to the 2023 annular solar eclipse to help you find more details.

Watching a solar eclipse can be an exciting experience, but it’s important to do so safely to avoid eye damage. Here are a few tips:
- Use certified solar eclipse glasses or solar filters. Make sure they comply with the international safety standard ISO 12312-2:2015, which means they can reduce visible sunlight to a safe level and block the sun’s UV and IR radiation.
- Do not use ordinary sunglasses or homemade filters. Normal sunglasses or homemade filters such as smoked glass or exposed film do not offer sufficient protection.
- Check your eclipse glasses/solar filters before using them. Make sure they are not scratched or damaged as this may compromise their safety. Also check the expiration date of the glasses or filter to make sure they are still safe to use.
- Use a solar filter for telescopes and binoculars. If you plan to observe the solar eclipse with a telescope or binoculars, be sure to use a solar filter that matches the lens. This protects your eyes and your equipment.
- Use indirect visualization methods. If you don’t have solar eclipse glasses or a solar filter, you can still view the eclipse indirectly by using pinhole projectors or projecting the image of the sun onto a white surface.
- Don’t look directly at the sun. Look away from the sun when putting on or taking off your eclipse glasses or solar filter.
By following these tips, you can safely enjoy a solar eclipse without putting your eyes at risk.

FAQs
When does a solar eclipse occur?
A solar eclipse occurs when the moon passes between the sun and Earth, partially or completely blocking sunlight. Solar eclipses can only occur during a new moon phase when the moon is between the sun and the earth.
Why don’t we have a solar eclipse every month?
Not every new moon results in a solar eclipse because the moon’s orbit is slightly tilted compared to the Earth’s orbit around the sun. Therefore, the moon is not always directly aligned between the Earth and the sun to produce a solar eclipse The shadow cast by the moon misses the earth.
What is the difference between a solar eclipse and a lunar eclipse?
A solar eclipse occurs when the moon passes between the sun and the earth, casting a shadow on the earth. A lunar eclipse occurs when the Earth moves between the sun and the moon, casting a shadow on the moon. Solar eclipses occur during a new moon, while lunar eclipses coincide with the full moon. During a solar eclipse, we observe the dark disk of the moon passing in front of the sun. During a lunar eclipse, the moon appears orange-red. For more information about lunar eclipses, see this article.
How long does a solar eclipse last?
A solar eclipse can last from a few seconds to a maximum of around 7.5 minutesdepending on factors such as the location and position of the observer on Earth and the path of the moon’s shadow on the Earth’s surface.
Can we see the stars during a solar eclipse?
During a total solar eclipse, when the moon completely covers the sun, it is dark enough to see the brightest stars and planets. However, the sky will not be as dark as night. Plus, since it only lasts a few minutes, your eyes don’t have time to adjust to the change in brightness, so you’re likely to only see the most noticeable objects. Additionally, Comet 12P/Pons–Brooks will reach magnitude 5 and could be visible near Jupiter during the April 8, 2024 total solar eclipse, which will also be visible.
Is it safe to watch a solar eclipse?
It is dangerous to look directly at the sun as its UV and IR radiation can damage your eyes. However, you can protect your eyes by using solar filters or solar eclipse glasses.
Do solar panels work during a solar eclipse?
As the solar eclipse approaches its peak, the energy output of your panels will noticeably decrease. The lowest point is reached during the complete solar eclipse. Afterwards, the energy level begins to rise again as the moon moves further away from the sun.
Solar eclipses: the essentials
Solar eclipses occur when the moon passes between the sun and Earth, partially or completely blocking sunlight. Depending on the position of the Moon and the observer’s location, one of three types of solar eclipses is visible – partial, total or annular. Sometimes a hybrid solar eclipse occurs and in some places a total solar eclipse occurs while in other places an annular solar eclipse occurs.
