Radio technology enables the extension of astronomical observations beyond light to other frequency ranges. This led to the discovery of numerous cosmic radio sources, the physical causes of which are explained, as is the operation of a radio telescope. Even small radio telescopes can observe radiation from the Sun and other radio sources, as well as 21-cm radiation from the Milky Way. Through interferometry, a much higher resolution can be achieved than with individual radio telescopes. As a result, radio astronomical research can contribute to many current questions in astronomy, cosmology, and physics.
