Imagine the Sky Tonight

What stars can you see in the sky this time of year? What shapes and stories can you imagine among them? We will give you a star map and teach you to find constellations, the starry patterns of the night sky. We might also find planets, star clusters, and other hidden treasures of the night sky. We will even imagine that we are flying away from Earth to make observations from far off in space.

How Big Is the Universe

You know that the Solar System is big. Is a galaxy bigger? How much bigger? How do astronomers measure how big and how far away the Moon or a star or a galaxy is? We will actively explore these questions, and we’ll take a tour from Earth to the farthest edge of the observable Universe.
