ESO Eclipse Activities

Extra Tours at ESO Observatories

ESO Observatories open their doors to the public every Saturday. For information regarding regular public tours, please see here.


With the occasion of the eclipse, we are organising the second edition of the #MeetESO social media gathering. Eight lucky social media enthusiasts will have the chance to witness the La Silla Total Solar Eclipse #LaSillaTSE without having to pay an entrance ticket and visit the La Silla Observatory. More information will be provided in the second half of July 2018.

Public Competition

If you are a national of an ESO Member State, you can win a trip to ESO’s La Silla Observatory in Chile to witness the total solar eclipse. More information will be provided end of July.


A space at La Silla Observatory will be reserved to a limited number of media representatives. If you are a journalist and you wish to be at La Silla on 2 July 2019, watch for the media advisory in August 2018.

School Competition

ESO will offer Chilean students the unique opportunity to witness the total solar eclipse from La Silla Observatory! More information about the competition for students to attend the event will be available in October 2018.

Live broadcast

In addition to the public event at La Silla, ESO plans to hold a live stream online and in locations throughout Europe, including the ESO Supernova Planetarium & Visitor Centre in Garching bei München, Germany. More information will be announced in 2018.

La Silla 50 Years

ESO sees the 2019 total solar eclipse as the greatest gift to commemorate 50 years since the official inauguration of La Silla Observatory on 25 March 1969.

Dedicated activities to celebrate this event will be soon included in the solar eclipse event programme.
