What is "outer space"?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: Why do we need to wear a space suit in space?; Why do things float around in space?; Why do stars twinkle? and more...

Outer space, I guess refers to outer space when they're thinking about things beyond our Earth. Once you get outside our Earth's atmosphere, I consider that outer space. Outer space is the region above our atmosphere. There's no air up there, you can't hear sound, and you get into the region of moons, planets, solar systems, stars, galaxies, and black holes; that's all in outer space.
