Ole Rømer Observatory

With the Ole Rømer Observatory, Aarhus now has a brand new area, a Science Park, where you can experience getting close to science both during the day and in the dark under the starry sky.

New telescope

Aarhus now has the largest working telescope in Denmark. The diameter of the mirror is crucial, as a larger mirror collects more light than a smaller one. This is equivalent to observing the night sky with a 70 cm eye, making the telescope the largest working telescope in Denmark.

Star shows

See the starry sky through Denmark's largest working telescope at the Ole Røber Observatory in Aarhus. Here you can get a look at distant stars and planets through the observatory's telescope or hear about astronomy in the 112-year-old building - weather permitting.

Through the observatory's telescope, you can get a look at the seasonal starry sky with the stars and planets that can be seen on the evening of the show. You might take a closer look at the Moon's craters, zoom in on Saturn's rings, spot a distant galaxy, or head outside for a closer look at a constellation.

Remember to book your ticket in advance.

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.
