COSMOS. Be a star.

The 3 dimensions of the universe.


Temporary exhibition on two floors / temporary exhibition Sphere

Patron: Mr. Frank De Winne, ESA astronaut

>>> 26.11.2010-25.04.2011 

The 3 dimensions of the Universe: what stage is the universe at and what do we know today of its history? Finally understand the big bang! How does our solar system work? Why does the sky provoke so many existential questions?


By providing the scientific basis necessary to understand the issue, the exhibition COSMOS. Be a Star takes the visitor on an educational and sensory journey of discovery through the 3 dimensions of the universe: scientific, artistic and philosophical, stimulating dialogue between the cosmos, the arts, science and philosophy.


With COSMOS. Be a Star, the Atomium plunges to the heart of the universe, taking a look at interpretations of the sky by scientists, poets, philosophers and artists. Between an exploration of the sky and a voyage through space in a most extraordinary vessel, you have the opportunity to discover other galaxies.


By providing the scientific basis necessary to understand the issue, the exhibition COSMOS. Be a Star offers a perspective on the 3 dimensions of the universe: scientific, artistic and philosophical.


An embodiment of this faith in scientific progress translated into a feat of architecture, the Atomium, a symbol of modernity since 1958, in its turn explores and explains the cosmos. Space, whether real or imagined, challenges and intrigues and COSMOS. Be a Star takes the visitor on an educational and sensory journey that stimulates dialogue between the cosmos, the arts, science and philosophy.


Based on an original idea from the Cité des Sciences in Paris, COSMOS. Be a Star is the fruit of collaboration with the Planetarium of the Royal Observatory of Belgium, without which our exhibition would not have been possible. The Planetarium joins our exploration of the cosmos not only with From the Earth to the Universe, an outdoor trail between our two buildings, but also with a new video spectacular, The Violent Universe.


What does the sky tell us? In the final analysis, things which are very much down to earth...

A violent spectacle!

From 26 November 2010, the Planetarium will be open on weekdays and every weekend, and the brand new 360° spectacular The Violent Universe will be available in Dutch, French and English. The Planetarium has purchased a high performance, multilingual audio system which will allow visitors to follow the spectacle directly in the language of their choice. And tourists from abroad will not be left out, as an English version will also be available.


There is no longer any excuse not to face the The Violent Universe, the Planetarium’s impressive new 360° film: explosions of stars, collisions of galaxies, destructive asteroids: the life of the Universe is certainly not that of a long slow river, as this impressive fulldome film shows. Prepare to be swept away!


This show is presented daily on week days at 16h00, on Wednesdays, Saturdays, Sundays and on public and school holidays at 2pm and 4pm. For information on the other shows:
