A STAR'S LIFE CYCLE-
The life of a star is explained in this video. A star begins as a large, cool mass of gas, which is forced to contract due to gravity. Temperature rises eventually lead to a process of nuclear fusion that produces a steady and vast output of energy. Its life can last about 10 billion years before its energy supply is exhausted and it collapses. Depending on their size, stars can finally become white dwarfs, supernovas, black dwarfs, neutron stars, or black holes.
