Stars are balls of heated gas called plasma. These particles are held together by gravity, the same force that prevents you from floating into space.
Stars consist of 71% hydrogen, 27% helium, and a tiny percentage of heavy elements like iron.
Stars shine through a process called thermonuclear fusion.
During this process, the hydrogen in the core of the star is transformed into another gas called helium. When this happens, the star releases energy that is converted into bright light, infra-red energy (heat), ultraviolet light, and radio waves.
