Some people say we are all made from "stardust." It's true. All heavy elements, like carbon, which is the foundational element of all life on Earth, come from the end of life process of a massive-size star, or supernova. A supernova is an explosion of a massive star, and the heavy elements are spread throughout the universe, which formed the Earth and the life on it.

Our sun is: (a.) a star; (b.) is an average size star; (c.) uses hydrogen to fuel it's nuclear fusion; (d.) has about 5 billion years yet to live; (e.) will eventually die in what is called a white dwarf.

The sun uses hydrogen for fuel in a process called nuclear fusion

The five stages in the life cycle of a star are:
