The International Astronomical Union will celebrate its 100 years in 2019 with multiple events and projects throughout the world. 100 Hours of Astronomy is the first global event marking the beginning of the celebrations.  

The Instituto de Astrofísica e Ciências do Espaço (IA) joins this global initiative with the Star Party – One Sky For All. Astronomical observations with telescopes, guided visits to the Lisbon Astronomical Observatory, workshops and an astronomy quiz are some of the activities for the 11th of January.

Astronomical observations with telescopes

18h00-01h00

Winter’s nightsky, with objects of great beauty, such as the Orion nebula, the Pleiades star cluster or planet Mars, will be explored throughout the night. 

We invite all participants to join the party and bring their own binoculars and telescopes. If you have no equipment to observe the sky, bring your camera or smartphone and take a shot of the Moon, using our telescopes.

Workshop “With the stars between your fingers”

18h00, 19h30, 23h00

In this 45-min workshop, ideal for families, one can build a 3D model of a constellation and understand how stars are distributed in space. In the end, the model can be taken home. 

Visits to the Lisbon Astronomical Observatory

18h00-00h30 (30 min each, with a break at 22h-23h)

This will be an opportunity to visit at night one of the most emblematic historical buildings of the capital, the Lisbon Astronomical Observatory.

Solar System at Scale exhibition

18h00-21h00

Often represented with similar sizes, the Solar System planets have very diverse dimensions. Discover them in this exhibition! 

Challenge “Do you know the nightsky?”

19h00, 20h30, 00h00

The night will also be filled with challenges. “Do you know the nightsky?”, a game against the clock, is one of IA’s suggestions for the public, with prizes for those that can identify more constellations.

Astronomy Quiz

21h30

The highlight of the night will be the Astronomy Quiz, with prizes for the winning team. One will be able to test his/her knowledge in a fun atmosphere and meet new people. And, if you are lucky, you may even have the help of an astrophysicist in your team. 

Important Notes

• The telescope observations depend on the meteorological conditions. A cold night is expected so we advise everyone to bring warm and confortable clothes and footwear.
• Instituto Superior de Agronomia (ISA), in which the Lisbon Astronomical Observatory is included, charges a parking fee in Tapada da Ajuda of 2€ per vehicle (excluding motorcycles).
