Fusion in Stars

Hydrogen, Helium and Dust

In space, clouds of interstellar matter can be found. These clouds are made up of hydrogen, helium and "dust". Within these clouds, clusters of the interstellar matter can begin to form.

Gravitational Forces

If the clusters of hydrogen, helium and dust get massive enough, they will contract into themselves from their own gravity. This pressure can cause the core of the cluster to become quite hot.

High Temperatures

If the star is massive enough to produce enough gravitational force to create internal temperatures of at least 10 million degrees, then fusion begins to occur, where by four hydrogens, fuse and create two heliums.
