When examining the universe at optical wavelengths you tend to see bright spots (stars/galaxies) with huge expanses of black inbetween. However, at microwave wavelengths you see a background glow, known as the cosmic microwave background. This is a relic from the very early universe and can tell scientists a considerable amount about the early structure of the universe.

∙ 7y agoJust as stars emit light that we can see with our eyes, they emit microwaves that can be detected by suitable detectors. Microwaves have properties that allow them to penetrate dust clouds in space that block visible light so we can make pictures and take measurements of areas that we cannot see with our eyes or optical telescopes.
