Thermonuclear reactions require extreme heat, typically found in stars or very controlled lab conditions. Scientists created a small-scale thermonuclear reaction replicating conditions inside a star.

Science Context
The term is mostly used in physics and astronomy to describe processes in stars or energy production. Astrophysicists study the thermonuclear processes that fuel stars like our Sun.

Fusion vs. Fission
Differentiate between thermonuclear (fusion) and atomic (fission) reactions; both release energy but have distinct processes. Thermonuclear fusion combines atoms, unlike nuclear fission which splits them.
