The unbearable lightness of the Universe
by Nelson Nunes, of Instituto de Astrofísica e Ciências do Espaço (IA)
In this month’s session of Noites no Observatório, discover the tricks and methods researchers use to measure the masses of the Earth, the Sun and the Milky Way.
You will also have the opportunity to learn that the Universe is expanding at an increasing rate and that this discovery tells us that only five percent of the Universe is actually the kind of matter we are familiar with.
After the public talk, there will be a music and effects show projected on the planetary dome, and observations of the night sky with telescopes will run continuously until midnight, if weather conditions allow.
Noites no Observatório are organised by the Instituto de Astrofisica e Ciências do Espaço, in partnership with the Planetário Calouste Gulbenkian – Centro de Ciência Viva.
Despite the event being free of charge, the access to the activity requires a registration here.
1) Due to the growing audience attending our activities and the fact that some people give up without notice, up to two emails 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.
2) You will need to pick a registration ticket at the entrance of the Planetário Calouste Gulbenkian between 9pm and 9:25pm on the day of the event. After 9:25pm, the tickets which have not been taken will be given to people on the waiting list and, on a first come first served basis, to people without registration.
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.
