Zusammenfassung

Im Jahre 1932 machte K. G. Jansky [2272]bei der Untersuchung von Kurzwellen-Funkstörungen mittels einer Richtantenne die erstaunliche Entdeckung, daß die Milchstraβe Radiowellen aussendet. In den folgenden Jahren hat Jansky das Phänomen bei Wellenlängen λ ≈ 12–14 m noch genauer untersucht. Doch erst G. Rebers Messungen (1939) der Verteilung der Radiostrahlung an der Sphäre mit einem großen Parabolspiegel (bei λ 1,8 m) überzeugten die bis dahin ziemlich zurückhaltenden Astronomen von der Realität der Erscheinung. 1940 versuchten L. G. Henyey und P. C. Keenan [2262]eine theoretische Deutung. 1946 entdeckten dann J. S. Hey, J. W. Phillips und S. J. Parsons [2264]die erste diskrete Radiostrahlungsquelle im Cygnus.
