Solar Eclipse is a rare astronomical event which occurs when the New Moon moves between the Sun and the Earth, blocking out rays and casting a shadow on different parts of Earth.
The shadow cast by the Moon is not big enough to engulf the entire planet, so the shadow is visible from certain regions only. This regions changes during the course of eclipse since the Moon and the Earth are in constant motion. Earth orbits the Sun and the Moon orbits the Earth and this is why solar eclipses seem to travel from one place to another.
TYPES OF SOLAR ECLIPSES:
PARTIAL SOLAR ECLIPSE: This type of eclipse is the most common type of eclipses. During Partial Solar Eclipse, the Moon appears to take a bite out of the Sun and can be seen as a Smiley face crescent Sun. The leftmost Eclipse in the above figure is an example of such.
However, it must be noted that a partial eclipse is dangerous to observe. It’s not possible to look at the Sun at that moment unless you are wearing a pair of safety glasses.
ANNULAR SOLAR ECLIPSE: This type occurs when the Moon’s disk is not big enough to cover the entire Sun. It happens when the Moon is at apogee- the furthest point from the Earth. In this case , the moon covers most of the Sun, but not all, of the Sun, creating a ring like structure known as “RING OF FIRE” eclipse.
This type of eclipse, like a partial eclipse , always dangerous to look with naked eyes. So, remember to wear a safety glass before watching it.
TOTAL SOLAR ECLIPSE: It happens when the Moon completely covers the Sun. It happens when the Moon is at Perigee-the closest point from the Earth. It is only visible to you if you are in the path where the Moon casts its darkest shadow, called as THE UMBRA.
This is the best type of eclipse, since for a few precious minutes you can look at Sun’s Corona without safety glasses and also you can stand under the Moon’s shadow since it causes a total blackout in that particular region.
HYBRID SOLAR ECLIPSE: A hybrid solar eclipse is a bit of all the three types , a partial, then a total or an annular solar eclipse. It depends on your location , since from one location you can see a total solar eclipse and from another you can see an annular type.
Hybrid solar eclipse are very rare and happen about once in every 10years. The next Hybrid solar eclipse is believed to happen on April 20,2023, in Australia and Timor Leste.

PROTECT YOUR EYES: Never look directly at the Sun without any protective eyewear. The best way is to wear a protective glass or to project an image using pinhole protector.
