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.

A partial lunar eclipse will coincide with this week's Harvest Moon, which also happens to be an exceptionally bright and large supermoon.

There’ll be a celestial show tonight with a stadium-sized asteroid fly-by, a Harvest full supermoon and partial lunar eclipse. Here's how to see it.
