Uppsala Astronomical Observatory

The Astronomical Observatory of Uppsala ( UAO; Astronomiska Observatoriet i Uppsala ) is the oldest astronomical observatory in Sweden. It was founded only in 1741, although since 1593 a chair of astronomy at Uppsala University and the University consisted archives contain lecture notes for astronomy, dating back to the 1480s.

In the 18th century Anders Celsius led here by his research and built in 1741 the first observation room. Celsius convinced the University, from the purchase of a large stone building with medieval origins in the center of Uppsala and had an observatory on the roof set up. He used the house at the same time as home and work. This observatory was used until 1853, when the new observatory was built, which is now known as " Old Observatory ". The Celsius house itself is still regarded as one of the few old buildings to a modern shopping street, but the observatory on the roof was demolished in 1857.

In the 19th century Anders Jonas Ångström inhabited the observatory building and led here by his astronomical, physical and optical experiments. His son, Knut Ångström researched here in the field of solar radiation.

In 2000, the observatory with the Institute of Space Physics teamed up for the Department of Astronomy and Space Physics and moved to the Ångström Laboratory ( Ångströmlaboratoriet ).

In addition to the facilities in Uppsala Observatory operates the observatory Kvistaberg in Sweden and the Uppsala Southern Station at Siding Spring Observatory in Australia.
