Stars have their own lives in space. They are glowing balls of gas just like our sun. They puff off layers of gas as they slowly fade away. Stars can be joined up to form constellations in our night sky. A group of billions of stars is called a galaxy. Most galaxies are spiral or oval shaped. One galaxy looks like a wheel. Some big stars explode. They leave a big cloud of gas. The stars in our universe have amazing lives.
