Ole Rømer Observatory

At The Ole Rømer Observatory in Aarhus you can enjoy the fascinating sight of the lunar landscape seen through telescopes. The planets Mars, Jupiter and Saturn are impressive as well. You might also be able to see a double star, which is two or more stars orbiting each other. Their different colours are normally clearly distinguished.

Tales about ancient and modern astronomy

If the sky is cloudy, the chances of taking a look through the observatory’s modern 11-inch telescopes are not good. The person making the presentation will talk about the history of the observatory, show you around the premises, and tell you about both ancient and modern astronomy.

The history of the observatory

The Ole Rømer Observatory in the suburb of Højbjerg, south of Aarhus, was erected in 1911, to be used by the German private astronomer Friedrich Krüger. After 1916, the observatory was run in collaboration between the city of Aarhus and the Danish State. From 1956 to 1974, the Institute of Astronomy at the University of Aarhus was located here, and the university is still in charge of scientific astronomical work at the observatory.

Today the observatory is mainly used for public presentations of astronomy. From September to April it is open approximately 15 nights each month. Be aware that you have to make a reservation in advance at the Steno Museum.
