A solar eclipse occurs when the moon moves between the earth and the sun, blocking the sunlight from reaching the earth for a short period of time. This natural phenomenon happens rarely and is a popular event for many astronomers, photographers, and skywatchers. The eclipse happens in different parts of the world at different times and it can last for a few minutes to a few hours.
The eclipse happens when the distance between the moon, the earth, and the sun is just right. The moon, which is about 400 times smaller than the sun and 400 times closer to the earth, appears to be almost the same size as the sun during an eclipse. When the moon aligns with the sun, it casts a shadow on the earth’s surface.
There are three types of solar eclipses: a total eclipse, a partial eclipse, and an annular eclipse. A total eclipse is a rare phenomenon when the moon fully covers the sun, and the sun’s corona is visible around the edges of the moon. During a total solar eclipse, the sky becomes dark, and stars may be visible, and temperatures may drop. Many people travel to different parts of the world to view the total solar eclipse, as it is truly an amazing and breathtaking sight. Seeing a total solar eclipse is a bucket list item for many people, and it is an experience that can be life-changing.
A partial eclipse occurs when the moon does not fully cover the sun, and only a part of the sun is blocked. The visibility of this phenomenon depends on the location of the eclipse, and the size of the partial eclipse can vary from a small crescent to almost 99%. An annular eclipse happens when the moon is farthest from the earth, and it appears smaller than the sun. During this eclipse, the moon does not completely block the sun, and a thin ring of sunlight is visible around the moon. These types of eclipses are less common than total and partial eclipses and are often not as popular.
How to Safely View a Solar Eclipse
Solar eclipses are stunning events, but it is essential to view it safely. It is never safe to look directly at the sun, even during a partial solar eclipse. It can damage your eyes permanently, so you must take precautions to avoid permanent damage. The safest way to view the eclipse is through special glasses or using filters on your camera lens.
Look for filters with ISO 12312-2 certification as these are the approved filters for viewing the eclipse. Welding masks or sunglasses are not safe viewing options, as they do not provide enough protection for your eyes. Another option is to use a pinhole camera, which you can easily make yourself.
A solar eclipse is an exciting and rare event that captivates people all over the world. The next total solar eclipse will occur on December 4, 2021, and will be visible in Antarctica, South Africa, and parts of Southern America. For those who are unable to view the eclipse, many countries and organizations live stream the eclipse for free. Whether you are a skywatcher, an astronomer, or just a curious person, a solar eclipse is truly one of the most mesmerizing and fascinating events that you can experience.
