Can Solar Eclipse Blind You

Introduction

Solar eclipses have long captivated the human imagination, evoking a sense of wonder and curiosity. These celestial events occur when the moon passes between the sun and the Earth, casting a shadow on our planet. As the moon obscures the sun, the sky darkens, and the sun’s corona becomes visible, creating a breathtaking spectacle. However, amidst the fascination surrounding solar eclipses, it is crucial to understand the potential dangers associated with looking directly at the sun during these events.

What is a Solar Eclipse?

A solar eclipse occurs when the moon aligns perfectly with the sun and the Earth, causing the moon to cast a shadow on our planet. There are three types of solar eclipses: total, partial, and annular. During a total solar eclipse, the moon completely covers the sun, revealing the sun’s corona, the outermost layer of its atmosphere. A partial solar eclipse occurs when the moon only partially covers the sun, while an annular eclipse happens when the moon is at its farthest point from Earth, resulting in a ring of sunlight around the moon.
