What does "Non-thermal" mean?
Table of Contents
Non-thermal emission refers to a type of radiation that is produced by high-energy particles, rather than by the usual thermal processes that occur when matter is heated. In simple terms, while most light we see comes from things that are hot, non-thermal emission comes from particles that are moving very fast and can create energy in different ways.
Where Do We See Non-thermal Emission?
Non-thermal emission is often observed in space, especially in stars and galaxies. For example, in some stars, smaller energy bursts known as microflares can produce non-thermal radiation. This radiation can tell scientists about the processes happening in those stars, like how they heat up or how particles are accelerated.
Why Is It Important?
Understanding non-thermal emission helps scientists learn more about the universe. It can give insights into events like solar flares, which are massive explosions on the sun that can affect space weather. By studying these emissions, researchers can better understand star formation and the behavior of different celestial bodies.
