Stars

Looking up into the sky at night you can see many stars and other objects. Early mariners used the stars for navigation. Today we know much more about the stars, planets, Sun, moon and other objects in our sky. Stars change over time. It may take millions to billions of years for a star to live out its life. That is a very, very long time! Stars are formed initially from gas and dust. They are composed mainly of the hydrogen gas. They are very hot and give off huge amounts of energy in the form of heat and light.

Our Sun is a medium sized star and has a life span of about 10 billion years, after which it will cease to exist. Stars are very far away from the Earth. The closest Star is about 23.5 trillion miles away.

Stars in the Sky

Stars are contained in galaxies. A galaxy contains not only stars, but clouds of gas and dust. There are billions of stars in the sky, which are far away from the Earth. You can see the stars as twinkling dots of light in the sky. Almost 2000 stars can be seen with your eyes and more stars can be seen with binoculars and telescopes. A star is a big ball of gas, which gives off both heat and light.

Twinkling of Stars

Twinkling Stars

Why do stars twinkle? Light comes from the stars in straight lines. When light comes to the Earth, it passes through layers of air that form the Earths' atmosphere. The air makes the light bent many times and in random directions. We will see the stars twinkling, when the light bends from the stars as it goes through the air.

Stars at Day and Night

Why can we see the sun but seldom see the stars during the daytime? Stars are always in the sky. Our sun makes so much light, it hides the other stars in the day time. At night, when the sun is not there in our part of the sky, we can see the other stars.

Star Patterns - Constellations

The Stars you see at night are very much like the Sun, but they are very far away. Hence, they appear to be smaller than the Sun. Stars appear in groups and single. A group of stars forms a constellation. You see different constellations at different times of the year. People in different parts of the world assumed different shapes and gave them different names.

One of the numerous constellations that we see in the night sky is the Big Dipper or the Great Bear; it is made up of 7 stars. Four stars form a quadrilateral, to form the body of the bear and 3 stars form the tail. These star patterns appear to move across the sky as the Earth rotates. As the Earth revolves around the Sun, you see these star patterns in different parts of the sky.
