The Blaauw Observatory of the University of Groningen is open for the nineteenth edition of the Night of the Night on Saturday 28 October 2023. During this night, when we set the clock back one hour, visitors can stargaze and there are all kinds of astronomical activities for young and old.

The Night of the Night is an initiative of the Nature and Environment Federations to draw attention to the beauty of the night and the consequences of light pollution. This edition is extra special because of the 15-year anniversary of the Blaauw Observatory and there is a partial lunar eclipse this evening.

  • From 7 p.m. onwards Planetarium show (every 45 minutes - ENG/NL)

In clear weather, visitors can stargaze through various telescopes. Among others, the Moon, star clusters and the planets Jupiter and Saturn can be admired. Even if the weather does not cooperate, the observatory can be visited. Then images of the universe taken with the Blaauw Observatory's Gratama Telescope will be presented.
