ASTRON is responsible for the operations of the Westerbork Synthesis Radio Telescope (WSRT) and the Low Frequency Array (LOFAR).


The astronomical research at ASTRON is closely aligned with the strengths of our facilities LOFAR and WSRT-APERTIF.

Diversity & Sustainability

ASTRON is committed to achieving a fair, welcoming, and sustainable work environment for all.


Met onze radiotelescopen nemen wij de meest zwakke signalen uit het heelal waar. Daardoor zijn zij kwetsbaar voor elektromagnetische storing. Met het tijdig treffen van de juiste maatregelen kan storing worden voorkomen.

Wireless Data Lab

Draadloze techniek lijkt vanzelfsprekend, maar de ontwikkeling ervan gaat niet vanzelf. Daarom hebben we bij ASTRON een proeftuin ingericht; het Wireless Data Lab.

LOFAR ERIC: Distributed Research Infrastructure for European Astronomical Research Launched

LOFAR ERIC (European Research Infrastructure Consortium) has been officially launched at its first Council meeting today. The world-leading LOFAR (LOw Frequency ARray) Distributed Research Infrastructure has already revolutionised low-frequency radio astronomy research, resulting in an avalanche of scientific publications in the past decade. LOFAR ERIC is now a single legal entity across the European Union. The LOFAR ERIC statutory seat is in Dwingeloo, the Netherlands, hosted by NWO-I/ASTRON (Netherlands Institute for Radio Astronomy; the original designer of LOFAR).

Opening Hallenhoes

Last Thursday (May 16) was the opening of the Hallenhoes in Exloo. In addition to the Schaapskooi shop, the TIP and the restaurant, ASTRON can also be found here. We are developing an escape room in collaboration with the Game Bakery. Maybe you've looked down into our basement. Those are parts of this escape room.

During the opening we showed a 3D visualization to the guests through VR glasses. This is because the escape room in the Hallenhoes still has to be built. Jetta Klijnsma also came by and listened to our ideas with great enthusiasm!

For now, we are busy further developing the escape room and hope that it can be used by many students at the end of October or beginning of November.

The escape room is about the journey of 3 researchers to the Big Bang. The three researchers each have their own role within the research team and the players choose one of these roles at the start of the game. The players are going trough three rooms, the past, the present and the future.
