The sun and other stars are composed primarily of hydrogen and helium. The hydrogen atoms combine by nuclear fusion resulting in helium.
The fusion of atoms powers the sun and other stars!
Hydrogen?
The core of the sun and other stars primarily consist of hydrogen atoms undergoing nuclear fusion to form helium atoms. This process releases a significant amount of energy in the form of light and heat, which powers the sun and allows it to shine.
Hydrogen atoms have one proton in their nuclei. When two hydrogen atoms fuse together they make one helium atom that contains two protons in its nucleus. This is called nuclear fusion, which powers the stars in the universe.
That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus.
The main source of energy in the Sun and other stars is fusion of hydrogen atoms into helium atoms.
The sun and other stars are powered by fusing hydrogen into helium in their first stage of life. Then as they get older the hydrogen runs out and the fuse helium and on up onto iron. Heavier elements come from novas and super novas.
Nuclear fusion. This is the process the sun uses to radiate all that light and heat.
The main fuel for nuclear reactions in stars is hydrogen. Through a process called nuclear fusion, hydrogen atoms combine to form helium, releasing energy in the form of light and heat. This process powers the stars and allows them to shine brightly.
fusion
The state of matter that exists inside the sun and other stars is called plasma. Plasma is a superheated state of matter in which atoms are stripped of their electrons, resulting in a soup of ions and free electrons.
During nuclear fusion, atoms of low-mass materials (such as hydrogen) combine to form a substance of higher mass (such as helium). This process releases large amounts of energy in the form of light and heat. It is the reaction that powers the sun and other stars.
