What do you see when you look up? From the roof of St. Thomas Church, not only can you see the city beautifully, but the sky is also infinitely beautiful. In astronomer Béatrice Bonga's audio tour, she takes you on a space journey to the black hole at the center of our galaxy. Which planets can you see from the roof? And how does a black hole work?
Listen to astronomer Béatrice Bonga's audio tour on the Skywalk and look at the stars differently from now on.
The audio tour can be listened to in both English and Dutch.
