Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies.

Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it. It is the leftover radiation from the big bang.

Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.

It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
