Microwave Astronomy

Microwave astronomy is the study of celestial objects and phenomena by observing the universe in the microwave part of the electromagnetic spectrum (with wavelengths longer than infrared but shorter than radio waves). It allows scientists to peer through cosmic dust clouds and detect signals from the early universe, galaxies, and the cosmic microwave background—the faint radiation leftover from the Big Bang. Using specialized telescopes, microwave astronomy reveals information about the universe’s structure, evolution, and the physical processes occurring in space, providing crucial insights that are often hidden in visible light observations.
