Radio astronomers are scientists who study celestial objects and phenomena by observing the radio waves they emit. Unlike optical astronomers, who use visible light to observe the universe, radio astronomers utilize radio telescopes to capture and analyze electromagnetic radiation at radio frequencies. This allows them to explore a wide range of astronomical subjects, including galaxies, stars, nebulae, pulsars, and cosmic microwave background radiation. Radio astronomy has contributed significantly to our understanding of the universe.
