The Life and Death of Stars (Astronomy) al Affiliation The Life and Death of Stars (Astronomy) Introduction Vividly stars are component that are seen on the sky. These fascinating components have a time when they are born, time to grow and can stay for a very long time and they also have a time to die. The skies contain gases like the hydrogen gas and dust that join together to form nebula, which is believed to be the birth place of the stars. When are stars born? People who study the stars also known as the Astronomers have come up with fascinating facts that molecular clouds which comprises of the thick dust and the gases are the birth place of stars .Once the hydrogen gas burns to helium gas they form a main star. These main stars include the sun, which produces enormous energy. (Journey to the Cosmic Frontier, p43)The enormous energy produced mainly depends on the mass of the star. What happens during the formation of the stars is, The gravity pulls dust and the gases inwards towards the core, then the temperatures increase leading to collision of the atoms .Finally the gas pressure comes to an equilibrium with the gravity and the accretion comes to a halt .These ordinary stars can live for long. The death of the “Stars” The ordinary stars exhaust hydrogen in its core and there is no longer source of heat to support the center against the gravitational pull. The hydrogen gas burns continuously in a shell at the center and the star changes to a red giant ball. This red giant ball will deposit the entire heat on our planets and will die finally.
