Physics Photo of the Week


Animated Moon Rise over Swannanoa


The moon rises at an angle oriented to the right when viewed from the northern hemisphere. If you were standing on the equator watching the moonrise, it would travel straight up, perpendicular to the horizon.  If you were in the southern hemisphere, the moon's rising path is inclined to the left.  This same relation holds for the paths of rising stars as well as the sun.  All frames were photographed by Julia Travis on Sept. 18, 2005.
