Uppsala University, founded in 1477, the oldest Nordic university, held a chair in astronomy since 1593, and the university archives contain even lecture notes on astronomy dating back to the 1480s.

In the 18th century, Anders Celsius (1701--1744), professor since 1730, performed his research in Uppsala and built his astronomical observatory on the roof of his private house Celsiushuset, Svartbäcksgatan 7-11, in 1741 -- it was the oldest in Sweden. In 1736, Celsius took part in an expedition in order to measure the shape of the Earth. In Uppsala he measured the brightness of stars. In addition he discovered that auroras disrupt the Earth’s magnetic field.
Already in 1742, Celsius defined the temperature scale named after him, degrees Celsius. In contrast to the Celsius scale used today, he set the boiling point of water at 0° and the freezing point at 100°. Carl von Linné (1707--1778) exchanged the fixed points of the scale -- in this form we use it nowadays.
The Celsius house itself still remains as one of few older buildings on a modern shopping street, but the observatory on the roof was demolished in 1857.

The new Uppsala Astronomical Observatory (UAO) -- now known as the "old observatory" -- was built in 1844--1852 under Gustaf Svanberg (1802--1882), inaugurated in 1853. Since 1864, a Meteorological Observatory was added with continous observatoions until today. Svanberg was also active in geomagnetical measurements, inspired by Gauß and Weber’s Magnetic Association of Göttingen.

Anders Ångström (1814--1874) (Wikipedia)

Anders Ångström (1814--1874), Professor since 1858, studied of the solar spectrum. In 1862, he provided evidence of hydrogen spectral lines in this context. He also determined the presence of other elements in the solar spectrum and published an atlas with spectral lines of the Sun in 1868 (Recherche sur les specters solaires, Uppsala). The unit of wavelength "Ångström" was named after him.

Leading astronomers of Uppsala Astronomical Observatory are: Carl Charlier, Bertil Lindblad, Knut Lundmark and Yngve Öhman, Hugo von Zeipel, Gunnar Malmquist, Erik Holmberg, and Bengt Westerlund.
 
Due to the light pollution of Uppsala, the Uppsala Astronomical Observatory (UAO) got a branch observatory, 50 km south of Uppsala, the Kvistaberg Observatory (1957). This was donated by Nils Tamm in 1944.
 
The "old" Uppsala Astronomical Observatory is used by the Uppsala Amateur Astronomers (UAA) since 2000.

In 2000 the (old) Uppsala Astronomical Observatory (UAO) merged with the Institute of Space Physics to form the Department of Astronomy and Space Physics and moved to the Ångström Laboratory. In 2008, another merger resulted in the Department of Physics and Astronomy, Astronomy and Space Physics becoming one of its divisions.
Address: Regementsvägen 1, SE-752 37 Uppsala.

New Uppsala Observatories

 

In addition to the facilities in Uppsala, the observatory operates the

  • Kvistaberg Observatory, Bro, Sweden (1957--2009),
    Observatory code    049 -- 59°30’06’’ N 17°36’24’’ E.
    Kvistaberg Observatory was a donation in 1944 from Nils Tamm (1876--1957), an active amateur astronomer, having studied astronomy under Nils Christoffer Dunér and Östen Bergstrand in Uppsala.
    The professors Åke Wallenquist and Gunnar Malmquist set up the new observatory (1957) and organized a large 1-m-Schmidt telescope in 1963. The directors after Wallenquist, 1948 to 1970, were Tarmo Oja, 1970 to 1999, Claes-Ingvar Lagerkvist, 1999 to 2007, Bengt Edvardsson, 2008 to 2009. Hundreds of minor planets had been discovered with the Schmidt telescope between 1975 and 2005, e.g. asteroid 3331 Kvistaberg.
     
  • Uppsala Southern Station at the Siding Spring Observatory (SSO) in Australia,
    Observatory code    413, 31°16’24’’ S, 149°03’52’’ E, Altitude 1156m (Mount Woorut)
    Uppsala Southern Schmidt Telescope (1956) with 0.6m correcting plate, 1957 until 1982 in Mount Stromlo Observatory, 1982 until 2013 Siding Spring Observatory, 31°16’24’’ S, 149°03’52’’ E, Altitude 1150m.
