Supermoon Lunar Eclipse: How Science Explains the Epic Night Sky Event

This month's highly anticipated "supermoon eclipse" may be a magical treat for skywatchers, but there's nothing supernatural about the event. On Sept. 27, skywatchers throughout North and South America, Europe, Africa, western Asia and the eastern Pacific Ocean region will witness a total eclipse that happens to occur when the moon looks abnormally large and bright in Earth's sky. It will be the first supermoon eclipse since 1982, and the last until 2033.
