How to watch a total eclipse of the moon
A total lunar eclipse is one of the most dramatic and beautiful – and easiest-to-view – of all astronomical events. During a total lunar eclipse, the sun, Earth and moon form a line in space. Earth’s shadow falls on the face of the moon. An entire hemisphere of Earth can see the eclipse, that is, the whole side of Earth on which it’s nighttime when the eclipse takes place. No special equipment needed. Just grab your lawn chair, go outside and plan to spend several hours watching the partial phases of the eclipse, followed by the totality itself, when the moon is completely covered by Earth’s shadow.
