Understanding Solar Eclipses

What is a Total Solar Eclipse?

A Total Solar Eclipse occurs when the Moon passes precisely between the Sun and Earth, completely blocking the face of the Sun. This celestial event turns day into night and reveals the Sun's outer atmosphere, the corona.

Annular vs. Partial Eclipses

An Annular Eclipse happens when the Moon is too far from Earth to completely cover the Sun, leaving a 'ring of fire.' A Partial Eclipse is when only part of the Sun is obscured. Our maps show the exact type visible from your location.
