Outlook,e the angular resolution is discussed. A short overview compiles important research areas of radio astronomy and contributions to today’s world view of astronomy and cosmology. At the end, some hints are given on how one can actively engage in radio astronomy oneself – even outside of large-scale re

Introduction: What Is Radio Astronomy?,, the cosmic background radiation, and quasars and pulsars. Modern interferometric methods and data processing make spectacular images possible, e.g. that of a black hole. But also outside the large research facilities, one can deal with radio astronomy, as an example, the radio telescope of the Nuremberg Observatory is presented.

How Does a Radio Telescope Work?,f the source, background and receiving system to the total received power to be represented and determined. The calculations and measurements required to measure the noise temperature of a source and, from that, its spectral intensity are presented.

Book 2022 cosmic radio sources, the physical causes of which are explained as well as how a radio telescope works. Even small radio telescopes can observe radiation from the Sun and other radio sources, as well as the 21-cm radiation from the Milky Way. Through interferometry, much higher resolution can be a
