Few know that just thirty kilometres from Helsinki lies a globally significant hub of technology making sense of the universe in radio waves – Metsähovi Radio Observatory, Finland’s only astronomical radio observatory, and one of the few in the world.

Metsähovi, celebrating its 50th anniversary in 2024, has broken data transfer world records, supplied technology to space shuttle missions and international research networks, and participated in capturing the first image of a black hole.

Metsähovi carries both global and local significance: in addition to being an active member of various worldwide radio telescope networks, its unique long-term observational programs are crucial to researcher around the world. Through multidisciplinary student projects, the observatory also sustains Finland’s versatile space expertise.
