In Galaxies, reader will travel to the depths of the universe, learning how galaxies are born, what kinds of technology are used to explore galaxies, and about galactic myths and legends.
Have you ever seen a galaxy? You can! Just look up on a moonless night. All the stars you see are part of the Milky Way galaxy. We live in the outskirts of this galaxy, which is made up of about two hundred billion stars. The Milky Way’s central plane looks like a creamy stream across the black sky. That “creamy stream” is really billions of stars.
Powerful telescopes reveal that there are billions of galaxies in the universe — the largest containing thousands of billions of stars. What other bodies “swim” in galaxies? How do galaxies form? These questions — and more– are answered in this fascinating KIDS DISCOVER title, perfect for the classroom or home.
