Public events at the Blaauw Observatory

UPDATE [Monday morning, November 11]: According to the weather predictions, it will be quite cloudy today. However, there is a chance of some gaps in the clouds, so we will set up the telescopes and you are very welcome this afternoon! If nothing is visible, we will show a livestream in the control room of the observatory.

Update 1: The enrollments for the Youth course starting mid- November can be found here. NOTE: The course is in Dutch

Update 2: This Monday, November 11, the planet Mercury will eclipse the sun, a so-called Mercury transit. Such an eclipse is too small to be visible with eclipse goggles, but can be seen with solar telescopes. Therefore, the Blaauw Observatory will open the doors to the public from 13:30 to 16:30. We are of course dependent on the weather, so keep an eye on this page, our facebook or our twitter for updates.

The Gratama Telescope is a beautiful instrument that could be used to look trough by eye. This is also a possibility for visitors! Have you never seen the craters on the Moon, the rings of planet Saturn or objects far in the universe? Then you should definitely visit us during our public evenings! The public evenings in the Blaauw Observatory are organized by the Kapteyn Institute (Faculty of Science and Engineering, University of Groningen) and SRON Netherlands Institute for Space Research.

Every spring we participate in the National Stargazing Days and every year in October the Nacht van de Nacht. From October to March, stargazing evenings are regularly organized, depending on the weather. During these public evenings, guided tours are given at the observatory itself. Besides that, anyone can watch stars with clear weather with the Gratama Telescope and some telescopes on the roof of the observatory. Furthermore, there are astronomical activities for young and old such as crafts, quizzes and lectures, and also regularly available, the Kapteyn Mobile Planetarium. The public evenings are always accessible free of charge.

For the upcoming activities, see the agenda at the bottom of this page. You can also stay up-to-date via our digital newsletter, Facebook and Twitter.

Saturday October 26, Night of the Nights

Come and marvel at the universe at this extra dark star-gazing evening during the 15th Night of the Nights!

The observatory will be open from 18:00. The Night of the Nights is an annual event on every last Saturday of the month October. This night the clock will reset for one hour. With the event, Nature and Environmental related federations ask your attention for the beauty and the importance of the dark nights. Through the entire country nightly events are organized and lights of hundreds of public buildings are being dimmed. On the Zernike Campus, various institutes corporate with the Night of the Night by dimming their lights or even turning their lights off.

For a detailed program we redirect you to the page of the event.

Large groups

In order to make an appointment, large groups, such as primary and secondary schools, are requested to contact us by email: sterrenwacht[at]astro[dot]rug[dot]nl . Having good weather would make it possible to set up a solar telescope, while having a guided tour during the day.

Astronomy course

The Kapteyn Institute regularly provides youth courses in astronomy for children up to 12 years. These courses consist of 5 course evenings. See this link for more information.

The Groninger Vereniging voor Weer- en Sterrenkunde (GVWS) also organizes periodic astronomy courses for adults in Winsum. For more information see their website:
