Finland's only astronomical radio observatory, Metsähovi Radio Observatory, turned 50 this year. To celebrate the anniversary, we organised a three-part Tähtitiistai lecture series to bring astronomy close to everyone's everyday life. In the lecture series, former and current people of Metsähovi talked about the history of Finnish space research, quasars, solar research and the secrets of black holes, among other things. The lectures were held in the cinema of the new Marsio building. You can find the recordings of the lectures at the end of this news item.
