A total solar eclipse occurs when the Moon passes directly between the Earth and the Sun, completely blocking the Sun's light. This alignment can only happen during a new moon phase and is visible from specific areas on Earth, known as the path of totality. During a total solar eclipse, observers within this path experience darkness for a few minutes, as the Sun is entirely obscured. The temperature may drop, and stars and planets can become visible in the daytime sky. Outside the path of totality, a partial solar eclipse is seen, where only part of the Sun is covered.
