How Does A Stars Life Begin. The diagram shows the life cycles of stars that are: The larger its mass, the shorter its life cycle.

The most interesting thought of all is that not only does life arise as a product of planetary processes, but in the fullness of time, on this. The star then enters the final phases of its lifetime. If a critical temperature in the core of a protostar is reached, then nuclear fusion begins and a star is born. Also, the temperature inside the cloud is low enough that a molecule can form in it.
