Stars operate on nuclear fusion. They operate on E=mc2, turning a little bit of mass into a whole lot of energy. Here's how: Hydrogen (atomic weight 1.008) is pulled into the star by gravity. Four hydrogen atoms get fused together to form one helium atom (atomic weight 4.003). If you look at the atomic weights (4H - 1He) there is a little bit of mass lost!. It turns to energy. Closer to the core of the star, helium fuses into heavier atoms like lithium and boron and carbon and oxygen. But iron is the last atom formed in regular stars by fusion. Fusion stops in all stars eventually as the fuel runs out. Because as smaller atoms get fused into larger atoms, it takes more energy and returns less at each step up until the atoms are iron. Then fusion would require more energy than the fusion could produce. This cooling results in a decrease of the cores' internal pressure that normally balances the force of gravity. Ultimately the star collapses and explodes. This process forms all the higher elements beyond iron. If it's heavy enough, the remnants become a neutron star, or even a black hole. If the star is big enough, it can reach a critical internal pressure that re-ignites the fusion process, but this normally happens suddenly and blows the star apart.

In nuclear physics and nuclear chemistry, nuclear fusionis the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy.
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
Yes, all stars produce energy through the process of nuclear fusion in their cores. This is where hydrogen atoms are fused to form helium, releasing vast amounts of energy in the form of heat and light.
Stars produce energy by fusing hydrogen into helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the star and allows it to shine.
As with our Sun (a star) by nuclear fusion.
Nuclear fusion
Stars like our sun and hydrogen bombs produce energy through nuclear fusion.
That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus.
Stars produce nuclear energy by fusion Stars form when contracting dust in a planetary nebula contract and get so hot that nuclear fusion occurs. It explodes, forming a porotostar. Nuclear fusion of hydrogen atoms combining to form helium atoms is what keeps the star glowing.

The fusion of Hydrogen into Helium causes heat and radiation to occur.

the energy sun and stars produce is fusion.
Yes, all stars release energy due to nuclear fusion.
Yes, stars are nuclear powered. They generate energy through the process of nuclear fusion in their cores, where hydrogen atoms combine to form helium, releasing massive amounts of energy in the form of light and heat. This process is what enables stars to shine and produce heat.
