There are eight planets in our solar system, and there could be billions more throughout space. Astronomers have been working for decades to locate and identify all of the planets they can. Readers will discover what methods these scientists use, how new technology has helped them see further than ever, and why some scientists think that faraway planets could be home to life forms unlike anything on Earth.
