STAR

 The star is a very big glowing ball of hydrogen gas lighted by nuclear reaction at its center. Stars are continually forming and dying throughout the whole universe. They are born inside huge gas clouds called Nebulas. The nebula is normally in the shape of a horse's head. The gas in a nebula is about twenty five thousand million times thinner than the air on earth. In spite of this, it has enough weak gravity to make parts of the nebula become small in the shape of blobs. As these blobs. get smaller, they tend to end up. Ultimately, they become so hot and dense that nuclear reaction starts inside them and they turn into stars. The heat and light generated from these new born stars can make nebulas glow in brilliant colors.

After shining for a very long time, say billions and billions of years, stars run out of fuel and die. The bigger stars have a very short life and very sudden and violent deaths. As they grow old, they turn red and expand to a vast size, and become almost red super giants. Ultimately, they destroy themselves in an explosion. brighter than a billion suns. On the contrary, smaller stars expand as they grow old into red giants, but they live much longer and die quietly. The remains of the dead stars are the most beautiful objects of the universe. Finally, the leftovers from the star death is recycled into new stars. The Milky Way Galaxy is a spiral-shaped cluster of stars and we see a part of it in the night
