Look at the sky. What do you see?
If it's day you'll see the Sun. If it's night you'll see the Moon. And if the sky is clear you'll see Stars. In big cities you may see only few hundred stars. But out in the country or on the ocean you'll see many thousands. You may even see Planets and, if you're lucky, a COMET.
There are people who look at the sky for hours and hours, night after night. They study stars, the planets, and other objects in the sky. These people are called "astronomers" . The word "astronomy" comes from Greek for "Star" and " arrangement".
Astronomers study the universe in many different ways. Some watch faraway objects. Other work in laboratories where they look at samples of meteorites, rocks from Moon, and space debris from other planets. Some try to make models of the different objects people have studied.
Not all astronomers get paid for the work they do. Some do it for a hobby. Such people are called "amateur astronomers".
How do astronomers study objects that are millions, even billions, of kilometres away ? They use powerful telescopes that make things look large enough to be seen in detail. Some telescopes are small enough to be held in the hand. Others are as big as a bus!
DID YOU KNOW ?
The planet Pluto is so far away from earth that the beam of a torch, travelling at the speed pf light, would take about five hours to get there.
