The Science Behind a Solar Eclipse

During a solar eclipse, the positions of the Sun, Moon, and Earth align in a specific way. The Moon’s orbit around the Earth is slightly tilted, so solar eclipses do not occur every month. When the Moon aligns perfectly between the Sun and the Earth, its shadow is cast onto the Earth’s surface, causing the eclipse.

The Moon’s shadow consists of two parts: the umbra and the penumbra. The umbra is the central, darkest part of the shadow, where the Sun is completely blocked. The penumbra is the outer part of the shadow, where the Sun is only partially blocked.

A solar eclipse occurs in several phases. It begins with the partial eclipse, when the Moon starts to move in front of the Sun, gradually covering more of its surface. As the Moon continues its path, it reaches the point of totality during a total solar eclipse, where the Sun is completely covered for a brief period. After the totality phase, the Moon moves away from the Sun, revealing a partial eclipse again until it completely passes by.

How to Observe a Solar Eclipse Safely

Observing a solar eclipse can be a thrilling experience, but it is crucial to do so safely to protect your eyes from permanent damage. Looking directly at the Sun during an eclipse can cause severe eye injuries, including blindness. Here are some important safety tips:
