Radio telescopes

Radio telescopes are large antennas that capture radio waves emitted by celestial objects, such as stars, galaxies, and quasars. Unlike optical telescopes, which collect visible light, radio telescopes can observe objects that are not visible to the naked eye. They convert the radio signals into digital data, which scientists analyze to learn about the universe's structure, composition, and behavior. These telescopes can operate day or night and are crucial for exploring phenomena like cosmic microwave background radiation and pulsars, providing insights into the origins and evolution of the universe.
