The only place in the universe where nuclear fusion can occur on its own is in the interior of stars.
After closely observing nature, and adapting its laws to fulfill human requirements,
our advanced civilization has succeeded in creating nuclear fusion at will, on a small
scale. Unfortunately, the only useful application successfully developed so far with our
superior intellect is the construction of nuclear bombs and weapons.
The sun, stars and hydrogen bombs.
In the sun and other stars
the nucleus.

These are not chemical reactions but thermonuclear reactions.
In this process, hydrogen-1 is converted into helium-4. Energy is freed up in the process.
A fusion reaction.
a chain reaction
It all comes from thermonuclear fusion of hydrogen inside the sun.
It simply means that thermonuclear fusion happens.
thermonuclear fusion and hydrogen becoming helium... :)
fusion is called thermonuclear for a good reason: it needs a lot of heat to get started.
Nuclear weapons' yield is derived primarily from fission. Thermonuclear weapon's yield is derived mainly from fusion. Thermonuclear weapons are multistage weapons -- x-rays from a nuclear primary trigger are used to trigger ablation in the pusher of the secondary to compress it, which is responsible for the fusion reaction.
These are not chemical reactions but thermonuclear reactions.
There is no fire in the sun, that is a chemical process. The process in the core is thermonuclear fusion.
Earth mainly gets its energy from the Sun's radiation.

Mainly in stars, although some is seen in the secondary of a thermonuclear weapon.
At the core of our sun, Helium is created by the thermonuclear fusion of Hydrogen.
