Get ready for a partial lunar eclipse and supermoon, all rolled into one. The spectacle will be visible in clear skies across North America and South America Tuesday night and in Africa

The night sky on Tuesday will treat us to a partial lunar eclipse during a supermoon. It’s an astronomical wonder that almost anyone in the Western Hemisphere can experience, and it’s the latest reminder that our home planet is part of a bigger cosmic system.

Not only is September's full moon also a so-called "supermoon" because of its size and brightness, but it's also due to be eclipsed by Earth.
