Stars obtain energy from a reaction called nuclear fusion. Nuclear fusion causes lighter elements to become heavier elements. The most common reaction fuses hydrogen into helium. But helium can fuse further, to even heavier elements. This releases energy until you reach the element iron. Anything heavier than iron consumes energy, rather than releasing it, when it is formed by nuclear fusion.

What else can I help you with?
What fuel burns in a main sequence star?
Hydrogen "burns" as it were, in "nuclear fusion" reactions to give helium and release energy.
Is enery released in stars as a result of fusion reactions?
Yes, energy is released in stars as a result of fusion reactions. In the core of a star, hydrogen nuclei combine to form helium, releasing a tremendous amount of energy in the process. This energy is what powers the star and allows it to shine.
Which type of radiation would you look for in a star to demonstrate that nuclear fusion was occurring inside?
You would look for high-energy electromagnetic radiation like gamma rays emitted from the star. This type of radiation is produced during nuclear fusion reactions when light atomic nuclei combine to form heavier nuclei and release energy. Detection of gamma rays can provide evidence that nuclear fusion is taking place in the core of a star.
What kind of reaction to provide a star with energy?
Stars generate energy through nuclear fusion, primarily converting hydrogen into helium in their cores. This process releases an immense amount of energy in the form of light and heat, which counteracts the gravitational forces trying to collapse the star. In more massive stars, fusion can also involve heavier elements, leading to the production of various elements up to iron. This fusion process is fundamental to a star's lifecycle and the energy it radiates into space.
What natural event provides enough energy for the nuclear fusion reactions that create the heaviest elements?
The violent creation of the solar system. There where much heavy elements on this planet before are civilization started its climb. These elements that we have now will deplete further and will not leave much left for the next civilization. It is a act of constant depletion.
Which star gets its energy from its core?
A star gets its energy from nuclear fusion reactions that occur in its core. These reactions fuse lighter elements, such as hydrogen, into heavier elements, releasing energy in the process. This energy is what fuels a star's brightness and heat.
What types of reactions occur in a star?
In a star, nuclear fusion reactions occur. These reactions involve the conversion of hydrogen into helium, releasing immense amounts of energy in the process. This energy is what powers the star and allows it to shine.
What is the central portion of a star that produces energy through nuclear reactions?
core
Does nuclear energy provide the sun's energy?
The Sun, like all stars, generates energy by fusion reactions deep within the star, where the heat and pressure cause atomic nuclei to fuse into heavier elements. Most of the Sun's energy comes from fusing hydrogen into helium.
What produces energy in the Sun alpha reactions proton splitting nuclear reactions or yellow dwarfs?
The energy output of the Sun derives from nuclear fusion reactions. A yellow dwarf is not a process, it's a type of star, of which the Sun is one.
What a large energy producing object in space that is made of gases undergoing nuclear reactions?
star
What is large energy producing object in space that is made of gases undergoing nuclear reactions?
star
What prevent the enormous amount of energy released from the fusion reactions at star's core from blowing the star apart?
Gravity. However, sometimes the star IS blown apart.
Is a star's energy a generated by nuclear reactions in the center?
Yes, that's correct. Specifically, by nuclear fusion.
What form of energy is does a star possess?
A star primarily possesses nuclear energy in the form of fusion reactions occurring in its core. This fusion process converts hydrogen into helium, releasing large amounts of energy in the form of radiation, heat, and light.
What is the central portion of a star called that produces energy through nuclear reactions?
The central portion of a star where nuclear reactions occur is called the core. In the core, hydrogen atoms fuse together to form helium, releasing energy in the process. This energy production through nuclear fusion is what allows stars to shine and emit light and heat.
Why is the sun a star and not planet?
For two reasonsPlanets orbit Stars.Stars emit energy as a result of nuclear fusion reactions occurring in their cores, planets do not.The solar system's planets orbit the Sun (making the Sun a Star by criterion 1) and the Sun emits energy as a result of nuclear fusion reactions occurring in its core (making the Sun a Star by criterion 2).
