Ahmanson Hall of the Sky

Imagine a world without day or night, with no change of seasons or annual cycles. It wouldn't be Earth, because the Sun and Moon dominate our sky and measure the march of time. Sunrise, sunset, and the passing of years and seasons--as well as the restless tides, monthly Moon phases, and awe-inspring eclipses--occur because the Earth and Moon move in relation to the Sun and each other.

The Sun is the most dynamic object in the sky. It warms our planet and makes life possible. As the closest star to Earth, it also offers us a glimpse into the nature of all stars.
