Night Sky:
When you look up at the sky on a clear night, what do you-see? Most of it is dotted with twinkling stars. You may see the moon or Venus as a bright point or Mars as a reddish one. Venus is sometimes seen in the evening just after sunset and, at other times, in the morning before sunrise. Except for the planets, all sthcr points of light are stars. From our planet Earth, on a really clear, dark night, we aan see .about 6,000 stars. Stars and Constellations The night sky is interesting. The stars seem to fall into certain patterns. You must have seen the Saptarishi, also known as the Big Dipper or the Plough. It is a part of a bigger group of stars called the Great Bear or the Ursa Major which is seen in the northern sky. We can see many different star patterns like the Hunters, the Lion, the Dog, the Balance etc. These pictures are not there really in the sky. Our imagination has put them there. The early star gazers and the ancient astronomers traced out these star patterms and named them after gods and heroes, objccts or creatures which these groups of sqrs resembled in their imagination.
