Chapter II
Where Stars Live

On Earth, gravity is the force that holds us to the ground. In space, it is the dominant force that holds the Universe together. Being much more massive than the Earth, stars like the Sun are almost always found in galaxies, which are enormous collections of stars that often number up into several hundred billion. Within galaxies, stars sometimes also group together into smaller collections known as clusters.
