The energy radiated by the Sun comes from nuclear fusiondeep in its core. Main sequence stars like the Sun fuse hydrogen into helium until they exhaust their supply, over billions of years. Eventually they may swell into red giant stars that fuse helium into carbon.

What is the Stars fusion?

Atomic fusion is the process by which elements which are brought into intimate contact, will undergo fusion, and will form a heavier element, and will emit energy in the process. Much of this released energy is the from the 'binding energy' of the atom.


90 percent of the stars including your sun are what stars?

90 percent of stars, including the Sun, are main sequence stars. These stars are in a stable phase of nuclear fusion, converting hydrogen into helium in their cores to produce energy. Main sequence stars like our Sun are the most common type of stars in the universe.


Most stars are classified as which of these?

Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.


What is the main fuel of stars?

The main fuel of stars is the most fundamental element in the universe -- hydrogen. Most stars spend most of their lives fusing hydrogen into helium. Only later in life do they fuse helium into heavier elements, and continue to fuse lighter nuclei into the elements up through iron. (According to many scientists, nickel really does not "count" in this chain for reasons that require an understanding of nuclear physics.)


Do most stars shine?

Yes, most stars shine by emitting light and heat through nuclear fusion reactions in their cores. This process generates energy that is released as light and heat, making stars visible to observers on Earth.

Where in the universe does fusion occur naturally?

Nuclear fusion is the process that powers stars, such as our sun.


What process releases the most energy into the environment?

The process that releases the most energy into the environment is nuclear fusion, which powers the sun and other stars. This process involves the fusion of hydrogen atoms to form helium, releasing large amounts of energy in the form of heat and light.


What is thermo-nuclear fusion?

Thermonuclear fusion is the process of nuclei joining together with the release of energy. This is the process which powers the stars, including our sun, and also the H-Bomb. Scientists hope to be able to make this work in a controlled way to produce energy which could then produce electric power. The most likely process for controlled use is between nuclei of deuterium and tritium, which are isotopes of hydrogen.


Is fusion an atomic process that is used to produce energy?

Fusion occurs when two atomic nuclei collide. The reaction that is produce by the collision can be used to provide energy. Fusion is the reaction that powers most active stars in the universe.


What is nuclear fusion in astronomy?

It's the process that takes place in the cores of stars, creating heavier elements out of lighter ones, and liberating nuclear energy that leaves the stars in the form of electromagnetic radiation.

What type of reactions can generate the most energy of nuclear?

Nuclear fusion reactions can generate the most energy compared to other types of nuclear reactions. Fusion involves combining light nuclei to form heavier nuclei, releasing large amounts of energy in the process. This is the same process that powers the sun and other stars.


What is a fuel for a star?

Most stars process Hydrogen using nuclear fusion and turn it into Helium.
