WebLife Cycle of a Star (Gcse Level) Stars start there life as a cloud of gas called a nebula. Mainly consisting of hydrogen and helium. The gases will then be drawn to a centre point of gravity which will then create a protostar. And then the nuclear fusion in the core of the star will star and the star will stabilize.

And oxygen. And... A larger star with more mass will go on making nuclear reactions, getting hotter and expanding until it explodes as a supernova. An exploding supernova throws hot gas into space. See more A star forms from massive clouds of dust and gas in space, also known as a nebula. Nebulae are mostly composed of hydrogen. Gravity begins to pull the dust and gas together. See more During this stable phase in the life of a star, the force of gravity holding the star together is balanced by higher pressure due to the high temperatures. The Sun is at this stable phase in its life. See more As the mass falls together it gets hot. A star is formed when it is hot enough for the hydrogen nuclei to fuse together to make helium. The fusion process releases energy, which keeps … See more When all the hydrogen has been used up in the fusion process, larger nuclei begin to form and the star may expand to become a red giant.
