Astronomy is the earliest of the scientific disciplines.
In historic times, astronomy was the study of the motions of the sun and moon and planets through the stars as well as more transcient events such as comets and eclipses. In modern times, astronomy has become much more complex. We can observe the universe at almost all wavelengths of electromagnetic radiation, from radio waves to gamma rays. There seems to be no end to the fascinating discoveries. This is a listing of astronomy departments and physics departments with strong emphasis on astronomy.
