Radio observatories are specialized facilities that use large antennas to detect and study radio waves emitted by celestial objects. These waves provide valuable information about the universe, including the composition, structure, and behavior of stars, galaxies, and other astronomical phenomena. By analyzing these signals, scientists can learn more about the origins and evolution of the cosmos. One of the most famous radio observatories is the Arecibo Observatory, which was located in Puerto Rico until its collapse in 2020. Radio observatories can also be part of larger networks, such as the Very Large Array in New Mexico, which consists of multiple antennas working together to enhance observational capabilities.
