Programme for the ESO Open House Day 2017 Now Available

16 October 2017

ESO, the world’s most productive ground-based observatory, will open its doors to the public on Saturday 21 October 2017 between 11:00 and 18:00 CEST. The ESO Open House Day event will be held at ESO’s Headquarters in Garching, near Munich, Germany. Visitors will have the opportunity to experience the world of ESO first hand by taking part in many different activities; the programme of activities for the day is set out below.

Our Open House Day is part of the Tag der offenen Tür that is taking place across the Garching research campus, as well as at several other local institutes.

If you need help to find your way around during the Open House Day, look out for our members of staff, who will be wearing name badges. As ESO is an international organisation, our staff speak several languages between them.

Media representatives who wish to attend the event are asked to confirm their participation by contacting
