The Development of Radio Astronomy
Abstract: Radio astronomy has been with us for only some 70 years, a short time when compared with the length of human (optical) astronomy observations. Nevertheless radio astronomy revolutionised our understanding of the Universe that we live in. Radio astronomers discovered quasars, pulsars, magnetic fields, the HI line, molecular lines, as well as the cosmic microwave background – a signature of cosmic evolution. Using pulsars radio astronomers confirmed the theory of relativity in detail and are on the way to detect gravitational waves. The observations in radio spectrum showed us the existence of dark matter and hence of dark energy. In my talk I will sketch all these developments and try to extrapolate to what radio astronomy can provide in the future. This last part of the talk I will base on the present and planned instrumental projects of radio astronomy like ALMA, LOFAR and the SKA.
