What is solar eclipse?

The stellar phenomena of the Moon coming in the way of the Sun and the Earth has caught the imagination of mankind as far as one can look back.

Most notably, it is said that there was one solar eclipse when Lord Ram fought demon duo of Khar and Dushan. Somewhat more well-known is the account of an eclipse having taken place during the Mahabharat war.

Our ancestors actually came up with a fantastic explanation for the blocking of the Sun in broad daylight. The usual suspect was a demon. His name was Rahu and he, rather his severed head, was blamed for causing the mischief.

Jumping to our times, the basic mystery of the solar eclipse has more or less been unraveled. What we the earthlings perceive as a solar eclipse is actually the shadow of Moon blocking the Sun to a varying degree. When the blockade is complete, it is called the total solar eclipse.

But how could a tiny moon stop the sunrays from reaching us? Yes, the Moon is no match for the Sun when it comes to the size. The Sun's diameter is 400 times larger than that of the Moon. And, interestingly, this is as many times far away the Sun is from the Earth than the Moon is. This makes up for the size and the Moon easily envelopes the gigantic star.

The solar eclipse, whether total or partial, is beautiful to look at. No wonder every time it happens, millions gather to witness it. But an old advisory must repeated each time. One should avoid the temptation of looking at the Sun while it is being eclipsed. It may appear easy, but is actually dangerous for the unprotected eyes.

One can always suggest the safest way to view a solar eclipse. Do it online.
