Radio Astronomy is a branch of astronomy that studies celestial objects by detecting the radio waves they emit. This technique allows astronomers to observe phenomena that are not visible in the optical spectrum, such as pulsars, quasars, and cosmic microwave background radiation. By using large radio telescopes, scientists can gather data about the universe's structure and behavior. Radio Astronomy has led to significant discoveries, including the detection of exoplanets and the mapping of galaxies. It plays a crucial role in our understanding of the cosmos and the fundamental processes that govern it.
