About this book.

For thousands of years people have looked up at the stars and wondered what lay beyond them.

Once people believed that the Earth was the centre of the Universe and that everything moved around it. Then they discovered that, in fact, the Earth moves around the Sun.

Today, powerful telescopes and space probes provide us with new, exciting information about the stars and planets, while rockets are able to send men and women into Space to explore. But even so, there is still much that we do not know about the Universe.

In this book you can find out about the Sun and the Moon and about the other planets that make up the Sun's family. You can discover how a star is born and learn about rockets and satellites. You will also find out about some of the still unsolved mysteries of the Universe.
