Beyond the Solar System
Caption: Barred spiral galaxy NGC 1300 photographed by Hubble Space Telescope.
Our solar system extends billions of miles from Earth. But there is still something bigger. It is the Milky Way, our galaxy. But wait, there's something even bigger than that - the universe!
There are billions of galaxies in space. A galaxy is a group of stars, gas, and dust that are bound together by gravity. If you look into the sky on a dark night, you can see our galaxy, the Milky Way. It is a shimmering belt that stretches across the sky. The Milky Way contains the solar system we live in.
