WebAll stars generate energy deep within their cores by one of the most powerful processes in the Universe: nuclear fusion. Hydrogen nuclei smash together, forming helium and releasing huge amounts of energy. This is why a star shines. The pressure of the gas heated by fusion supports the star against its own gravity. WebWhen an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits. The Electromagnetic Spectrum
