NRAO (National Radio Astronomy Observatory)

The National Radio Astronomy Observatory (NRAO) is a U.S.-based organization that operates large radio telescope facilities to study the universe. Unlike optical telescopes that observe visible light, radio telescopes detect radio waves emitted by cosmic objects like stars, galaxies, and black holes. This allows astronomers to explore phenomena that are hidden or invisible in regular light. NRAO's facilities help scientists understand the universe’s structure, origins, and the processes occurring in distant cosmic regions, contributing essential insights into astrophysics and cosmology.
