Open House Day 2017

Open House Day 2017

On Saturday 21 October 2017, the European Southern Observatory (ESO) will open its doors to the public between 11:00 and 18:00 CEST. This event is part of the Open House Day activities for the whole Garching research campus and several other local companies.

Visitors to ESO will have the opportunity to experience the world of ESO first hand by taking part in activities such as:

  • See ESO's Headquarters buildings — participate in guided tours through the innovatively styled office building and technical building.
  • Learn how ESO creates artificial stars, see what mirror prototypes for the Extremely Large Telescope look like and more;
  • Virtual and 3D tours — embark on all-inclusive journeys into and around some of ESO’s most breathtaking sites and groundbreaking instruments;
  • Live connection to Paranal and ALMA — connect to ESO's Very Large Telescope at Paranal and to ALMA, the largest astronomical project in existence, consisting of 66 antennas located at 5000 metres above sea level on the Chajnantor Plateau in Chile;
  • Talks, podcasts and documentaries — listen, watch, and learn more about ESO;
  • Children’s activities – find out the ingredients of a comet in our comet making factory; have your infrared photo taken;
  • Solar observations — watch the Sun through a telescope, if weather allows;
  • Plus much more.

Visitors do not need to book a visit in advance. You can simply show up at the activities you are interested in. ESO has a cafeteria where light refreshments will be available.
