Summary
The Sun and the solar system have always been a matter of great intrigue for mankind. The Sun provides us the light and heat that is essential for our survival. But just like every living being on this planet, the Sun has a limited life. The video series takes us through the life cycle of the Sun. This video which is one from the series of 5 videos explains the process of birth of the Sun. It started with the dust and gas debris from exploding stars developing into a molecular cloud comprising of hydrogen. The gravity brought hydrogen atoms together and the cloud collapsed on itself over a period of millions of years. Due to fusion between the hydrogen atoms huge amount of energy was released and the force that emanated from this fusion pushed the molecular mass outwards against the force of gravity. The balance between the forces of outward push due to fusion and that of inward pull due to gravity gave rise to the Sun. The video also gives an insight into Genesis, a mission to analyze the Sun and its properties being pursued by NASA.
