Starry sky. Children's Encyclopedia. Ed. Fedanova Yu., Skiba T.

dear friend! Look at the sky on a cloudless night.

It is strewn with stars. Small luminous dots in a black emptiness attracted the attention of people from antiquity.

For many thousands of years, humanity had no idea that it was in the sky: what it consists of, how it is arranged. People could only observe and make assumptions. Cognition of the cosmos is one of the most exciting stories that we know.

Science that studies space is called astronomy. She went a long way from compiling calendars of the farmers to the launch of interplanetary space stations. The more accurately and more perfect devices for observing the stars and planets, the more scientists learn about the universe. After people began to launch telescopes and scientific probes into space, astronomy makes several important discoveries every year.

This book is about how human curiosity, a craving for knowledge, the development of astronomy and technology, mathematics and physics, the courage of the discoverers step by step brought people closer to understanding the structure of the Universe.
