When Does a Solar Eclipse Happen?

A solar eclipse can only happen during a new moon phase when the moon’s position is between the sun and the Earth. There are three types of solar eclipses: total, partial, and annular. A total solar eclipse occurs when the moon completely covers the sun, creating a total blackout. A partial solar eclipse happens when the moon only partially covers the sun, leaving a ring of light visible. An annular solar eclipse happens when the moon is too far away from the Earth, and it appears smaller than the sun, leaving a ring of light visible.


The frequency of solar eclipses varies from year to year. In some years, there may be none, while in other years, there may be as many as five. The last total solar eclipse visible in India happened on August 21, 2017, and the next one is predicted to occur on April 20, 2023.

How to Safely View a Solar Eclipse

It is essential to take precautions when viewing a solar eclipse to avoid damaging your eyes. Looking directly at the sun during a solar eclipse, even for a few seconds, can cause permanent eye damage, including blindness. Here are some safe ways to view a solar eclipse:

  1. Wear Solar Eclipse Glasses: Special glasses with a solar filter can protect your eyes from the sun’s harmful rays. These glasses should have an ISO 12312-2 certification to ensure their safety. Do not use regular sunglasses, even if they are very dark, as they do not provide sufficient protection.
  2. Use a Pinhole Viewer: A pinhole viewer is a simple device that can be made from a cardboard box, paper, and aluminum foil. Cut a small hole in the cardboard box and cover it with aluminum foil. Poke a small hole in the aluminum foil and hold the box up to the sun. You will be able to see an image of the eclipse projected onto the back of the box.
  3. Use a Telescope or Binoculars: If you have a telescope or binoculars, you can use them to safely view the eclipse. However, you must use a solar filter to protect your eyes. Never look through a telescope or binoculars at the sun without a solar filter.

In conclusion, a solar eclipse is a rare and spectacular astronomical event that everyone should experience at least once in their lifetime. However, it is crucial to take precautions when viewing a solar eclipse to avoid eye damage. By following the above safety tips, you can enjoy the beauty of a solar eclipse without risking your eyesight.
