why do you think that solar energy has a bright future in india

 The sun is in the centre of the solar system. It is huge

and made up of extremely hot gases. It provides the

pulling force that binds the solar system. The sun is

the ultimate source of heat and light for the solar

system. But that tremendous heat is not felt so much

by us because despite being our nearest star, it is far

away from us. The sun is about 150 million km away

from the earth.

How wonderful it is to watch the sky after sunset! One

would first notice one or two bright dots shining in

the sky. Soon you would see the number increasing.

You cannot count them any more. The whole sky is

filled with tiny shining objects – some are bright, others

dim. It seems as if the sky is studded with diamonds.

They all appear to be twinkling. But if you look at

them carefully you will notice that some of them do

not twinkle as others do. They simply glow without

any flicker just as the moon shines.

Along with these bright objects, you may also see

the moon on most of the days. It may, however, appear

at different times, in different shapes and at different

positions. You can see the full moon only once in about

a month’s time. It is Full moon night or Poornima. A

fortnight later, you cannot see it at all. It is a New

moon night or Amavasya. On this day, you can watch

the night sky best, provided it is a clear night.

Do you wonder why can’t we see the moon and all

those bright tiny objects during day time? It is because

the very bright light of the sun does not allow us to see

all these bright objects of the night sky.

The sun, the moon and all those objects shining in

the night sky are called celestial bodies.

Some celestial bodies are very big and hot. They

are made up of gases. They have their own heat and

light, which they emit in large amounts. These celestial

bodies are called stars. The sun is a star.

Countless twinkling stars in the night sky are

similar to the sun. But we do not feel their heat or

light, and they look so tiny because they are very very far

from us.
