The dark side of the Force

Noites no Observatório - O Lado Escuro da Força

The public talk this month is titled “The dark side of the Force” and the speaker will be Tiago Barreiro, of the Instituto de Astrofísica e Ciências do Espaço.

After the public talk, there will be a music and effects show projected on the planetary dome, and observations of the night sky will run continuously until midnight, if weather conditions allow.

Noites no Observatório are monthly sessions comprising of a public talk, given by researchers of Instituto de Astrofísica e Ciências do Espçao (IA), and observations of the night sky with telescopes.

Noites no Observatório are being organised since 2009 and are regularly framed within national and international events, such as the European Researchers Night or the Science and Technology Week.

Free entrance


Although the entrance is free of charge, the access to the activity requires a registration here.

Due to the growing audience attending our activities and the fact that some people give up without notice, an email will be sent asking for confirmation. The lack of a reply within 48 hours after the reception of this confirmation request will be taken as a dropout and the registration will be cancelled. For this reason, please check your email inbox regularly in order to confirm your attendance in the activity.

The observation of the night sky depends on the weather conditions. As this is run outside, we recommend the use of warm clothes.

The talk is given regardless of the observations. The Calouste Gulbenkian Planetarium will open its doors half an hour before the event starts.

The public talk is given in Portuguese.
