Scenarios about 'radio astronomy'
The scientific field studying celestial objects through their radio frequency emissions, developed in the 1930s when Karl Jansky detected radio waves from the Milky Way. Radio astronomy allows scientists to observe phenomena invisible to optical telescopes, including pulsars, quasars, and cosmic background radiation, providing crucial insights into the universe's structure and evolution that have fundamentally altered our understanding of astrophysics.
