How Many Stars Are There?

Curated and Reviewed by Lesson Planet

Starting with a seemingly simple question, a video covers how many stars are visible with the human eye. Then it explains how many stars are in the Andromeda galaxy next to ours. The most interesting part is when you view a single square of dark space and learn how many stars there really are in that tiny segment of the vastness of space.
