Did you know that a solar eclipse happens when the moon blocks the sun's light from reaching Earth? This cosmic event has fascinated humans for centuries, sparking myths and scientific curiosity alike. During a solar eclipse, the sky darkens, temperatures drop, and animals might even act like it's nighttime. There are different types of solar eclipses: total, partial, and annular. Each offers a unique spectacle. But remember, never look directly at a solar eclipse without proper eye protection! Special glasses or viewers are a must to safely enjoy this celestial show. Eclipses don't happen every month because the moon's orbit is tilted, so they are rare and special. People travel across the globe to witness these events, making it a memorable experience. Whether you're a seasoned eclipse chaser or a curious newbie, there's always something magical about watching the sun and moon dance in the sky.
What is a Solar Eclipse?
A solar eclipse happens when the Moon moves between Earth and the Sun, casting a shadow on Earth. This cosmic event can be a thrilling spectacle, but there's more to it than meets the eye.

Eclipse Path: The path where a total eclipse is visible is called the path of totality. It’s usually about 10,000 miles long but only 100 miles wide.
-
Eclipse Duration: A total eclipse can last up to 7.5 minutes, but most are much shorter. The longest recorded was 7 minutes and 32 seconds.
-
Baily's Beads: Just before and after totality, sunlight shines through the Moon's valleys, creating bright spots known as Baily's Beads.
