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.

Making discoveries
in radio astronomy

ASTRON is the Netherlands Institute for Radio Astronomy, and is part of the Institutes organisation of NWO.
TOPIC-led consortium develops CSP-Low for SKA

The SKA telescopes are currently in the construction phase, and with it the central signal processor (CSP) for the SKA Low frequency telescope, called CSP-Low. CSP-Low will be integrated and delivered to site by a consortium led by the Dutch company TOPIC; ASTRON is one of its subcontractors. One of TOPIC’s specializations is designing and developing hardware, firmware, and software for sophisticated systems.

People of ASTRON: Tom Kamphuis

In People of ASTRON we share stories about the people at ASTRON. Who are the people behind the discoveries and innovations and also, who are the people that make sure that everything runs smoothly? Tom Kamphuis is Head Software Delivery and loves that he can contribute to groundbreaking science.

ASTRON lanceert proeftuin voor ondernemers

Om onze kennis over het heelal te vergroten, verlegt ASTRON voortdurend de grenzen van de technologie in haar radiotelescopen. Deze expertise stellen wij nu ter beschikking om de innovatieve kracht van ondernemers te vergroten. Hiertoe lanceren we het Wireless Data Lab (WDL), een proeftuin waarmee ASTRON haar kennis en faciliteiten op het gebied van draadloze dataoverdracht beschikbaar stelt aan het bedrijfsleven en andere instellingen.

ASTRON-led consortium working on SKAO

A consortium led by ASTRON is developing important software components for processing the vast amounts of data that the soon-to-be largest radio telescope in the world will produce.

Introducing... Dr. Kenzie!

On September 16th, 2022, ASTRON/UvA PhD candidate Kenzie Nimmo successfully defended her thesis, entitled Zooming-in on the sources of fast radio transients at the Aula of the University of Amsterdam. The thesis was also awarded the rare distinction Cum Laude, based on the reports from the committee and additional external referees. One of Kenzie's "paranymphs" audibly gasped when this was announced.

In her thesis, Kenzie presents several pioneering studies of fast radio bursts (FRBs), using the European VLBI Network as well as single-dish voltage data from the 100-m Effelsberg telescope. This allowed her to zoom-in in both time and space to pinpoint exactly when and where FRBs happen. She investigated the diversity of environments in which FRB sources are found (from Milky-Way-like galaxies to globular clusters), and showed that we have only just scratched the surface in terms of exploring the breadth of FRB-like signals we can detect - on timescales as short as nanoseconds, and with luminosities that span many orders of magnitude.

Kenzie is now off to MIT, where she was awarded a prestigious Kavli fellowship in astrophysics to continue her research using the CHIME/FRB telescope. CHIME/FRB is being expanded with outrigger stations, and Kenzie will apply her expertise to localise a large sample of FRBs to their host galaxies. This will transform our understanding of the phenomenon as well as enable many exciting applications in astrophysics and cosmology.

Many of ASTRON's scientific discoveries were made with the Dwingeloo radio telescope. To tell you a bit more about this, we have published the second video in our virtual tour.

Daily image of the week. To enrich the exhibition of Nebra sky disc at the @DrentsMuseum, ASTRON hosted a stand outside, demonstrating how we explore the universe nowadays, compared to how people did this 3,500 years ago (when the Nebra disc was made).

This week is #Pride Week. A more #diverse workforce fuels creativity, compassion, understanding, and the feeling of kinship and inclusion. At ASTRON we highly value diversity and make constant efforts to increase the diversity of our workforce.

Op 7 en 14 augustus staan we voor het @DrentsMuseum, dat de #Nebraschijf, een van de oudste sterrenkaarten ter wereld tentoonstelt. ASTRON-onderzoeker @AndreOffringa geeft binnen een lezing en wij doen voor het museum wat leuke proefjes. Hopelijk tot dan!
