Question

Quizplus · Accepted Answer

Supernovae are responsible for heating the bulk of the very hot intercloud gas. The explosion of a supernova releases a massive amount of energy in the form of shock waves that heat and compress the surrounding gas, resulting in the production of X-rays and high-energy particles. While high-energy radiation from stars and young O and B stars also contribute to heating the gas, they are not the primary source.
