Radio astronomy is a branch of astronomy that involves studying celestial objects and phenomena through the analysis of radio waves emitted by them. This research area allows astronomers to observe objects and events in the universe that may not be easily visible through traditional optical telescopes. Radio telescopes are used to capture and analyze these radio signals from space, providing valuable insights into the composition, structure, and dynamics of objects such as stars, galaxies, black holes, and the cosmic microwave background radiation. Radio astronomy plays a key role in our understanding of the universe and has led to important discoveries such as pulsars, quasars, and the cosmic microwave background radiation.
