Pictures in the SkyLong ago, people looked up in the

night sky and saw patterns in the stars. The patterns seemed to make shapes. Ancient people gave these shapes names. Some shapes were named after animals. Some were named after people. These names are still used today.

The Ancient Greeks studied the night sky.
