The Music of the Stars

Noites no Observatório - Abr17

The Music of the Stars

By Margarida Cunha, of Instituto de Astrofísica e Ciências do Espaço (IA)

The first contact with astronomy is almost always through the observation of the stars in the sky, so distant and, apparently, so much alike.

In April’s Noites no Observatório we will discover what the Music of the Stars has to tell us about the size, the mass, the age and the structure of these astronomical bodies.

In the company of Margarida Cunha, of Instituto de Astrofísica e Ciências do Espaço, we will also talk about the importance of the study of this ‘music’ to other areas in astronomy, like the characterisation of planetary systems found orbiting other stars, and the study of our own galaxy.

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.



3 hours

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.
