Here's what happens:
* The Sun, Earth, and Moon align perfectly. The Moon passes directly between the Sun and Earth, casting its shadow on Earth.
* The Moon blocks the Sun's light. This creates a temporary darkness during the day.
* The shadow cast by the Moon falls on Earth. The area within the shadow experiences a total solar eclipse, where the Sun is completely blocked out.
* The outer regions of the shadow experience a partial solar eclipse. This means the Sun appears partially covered by the Moon.
It's important to remember that solar eclipses are relatively rare events, and they don't occur at every New Moon because the Moon's orbit is slightly tilted relative to Earth's orbit around the Sun.
