WebMar 31, 2024 · Heat generates pressure, and the pressure created by a star’s nuclear burning also keeps that star from collapsing. A star is in balance between two opposite forces. The star’s gravity tries to squeeze the star into the smallest, tightest ball possible. But the nuclear fuel burning in the star’s core creates strong outward pressure.

WebJun 29, 2000 · In reaction 1, two hydrogen nuclei ( 1 H, protons) are fused to produce a heavy hydrogen nucleus ( 2 H, a deuteron). This is the usual way nuclear burning gets started in the sun. On rare occasions, the process is started by reaction 2. Deuterons produced in reactions 1 and 2 fuse with protons to produce a light element of helium ( 3 He).

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.
WebEvery star has its own life cycle, ranging from a few million to trillions of years, and its properties change as it ages. Birth. Birth. Stars form in large clouds of gas and dust called molecular clouds. Molecular clouds range from 1,000 to 10 million times the mass of the Sun and can span as much as hundreds of light-years. chingford hatch pharmacyWebWhen 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.
