Uppsala Astronomical Observatory
The Uppsala Astronomical Observatory (UAO; Astronomiska observatoriet i Uppsala ) is the oldest astronomical observatory in Sweden . It was founded only in 1741, although since 1593 a Chair for Astronomy at the University of Uppsala was and the university archives include lecture notes in astronomy, dating back to the 1480s.
Anders Celsius carried out his research here in the 18th century and built the first observation room in 1741. Celsius convinced the university council to buy a large stone building with medieval origins in the center of Uppsala and had an observatory set up on the roof. He used the house as both an apartment and a place of work. This observatory was in use until 1853 when the new observatory, now known as the "Old Observatory", was built. The Celsiushaus itself still exists today as one of the few old buildings on a modern shopping street, but the observatory on the roof was demolished in 1857.
In the 19th century, Anders Jonas Ångström lived in the observatory building and carried out his astronomical, physical and optical experiments here. His son, Knut Ångström , conducted research in the field of solar radiation here .
In 2000, the observatory merged with the Institute of Space Physics to form the Department of Astronomy and Space Physics and moved to the Ångström Laboratory (Ångströmlaboratoriet) .
In addition to the facilities in Uppsala, the observatory operates the Kvistaberg observatory in Sweden and the Uppsala Southern Station at the Siding Spring Observatory in Australia .
