Permanent exhibition of the Observatory – The Universe and I

The Meridian Hall recaptures the unique atmosphere of an old astronomical observation facility with its large observation equipment still in the original places.

The exhibition takes you on a journey into space to explore phenomena in our own solar system and reveal the life cycle of stars as well as the structure and scale of our universe and the different wavelengths of light. Have you ever wondered what you would look like on an infrared camera? You also get to peek into a cloud chamber and see traces of cosmic particles!


Did you know that you are "a child of the stars"? The chemical elements in the human body were also created through nuclear reactions within stars over the course of billions of years. In the exhibition you can also touch a real meteorite that was formed five billion years ago!

By booking a guide in advance for your visit, you can also enjoy the atmosphere of the old observation towers and admire the star-lit Helsinki "sky" in the planetarium located in the vault.
