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.


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.
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.

NenuFAR officially becomes a LOFAR super station

The low-frequency radio telescope NenuFAR will be connected to the international LOFAR telescope, operated by ASTRON, the Netherlands Institute for Radio Astronomy.

Westerbork and the future of GigaHertz astronomy

The Westerbork Synthesis Radio Telescope (WSRT) has been a powerhouse of science since it began operations in 1968, making more than 50 years of discoveries in radio astronomy happen. Looking forward, we will strengthen our activities in Westerbork on VLBI, GNSS, data releases of the Apertif surveys, and developing next-generation technology for our instruments.

EXPOWER’s Ice Breaker: 'Unleashing the power of exponential functions'


From May 16 to 19, ASTRON co-organised the Ice Breaker Meeting of the EU funded project EXPOWER (“EXPOnential analysis emPOWERing innovation”). Under the umbrella of the H2020 Marie Skłodowska-Curie Actions, this multi-year Research and Innovation Staff Exchange (RISE) program combines a broad spectrum of key research activities in exponential analysis. The EXPOWER project is coordinated by the University of Antwerp in Belgium and encompasses eight universities, three research institutes and seven companies from nine countries. ASTRON is among the three participating research institutes. The other two research institutes are the National Institutes of Health (NIH) from the US and the Industrial Technology Research Institute (ITRI) from Taiwan.

As a topic in computational mathematics, exponential analysis might sound remote, but it touches everybody’s life in many unexpected ways. For example, a substantial amount of research in signal processing is essentially dedicated to the analysis of exponential functions whose exponents are complex. The exponential functions with real exponents are used to portray relaxation, chemical reactions, radioactivity, heat transfer, fluid dynamics.

Although “exponential” is often used to mean “very fast”, making progress in exponential analysis is not so fast because of the intrinsic difficulty of the underlying mathematical problems. Together with the antenna team of the Square Kilometre Array (SKA) from Stellenbosch University in South Africa and the Computational and Engineering Mathematics (CEMath) group from the University of Antwerp in Belgium, ASTRON seeks to strengthen the existing collaborations and expand its scientific network with scientists and stakeholders in the development of exponential analysis, from computational mathematics and various application domains.

The EXPOWER project started on October 1st last year. Due to the travel restrictions, the Ice Breaker Meeting was postponed until now. The meeting at ASTRON is attended by both on-site and on-line participants and marks the official kick-off of the consortium. More information is available from the project website:

This week @ASTRON_NL hosted the first consortium-wide Ice-Breaker event for the @EU_H2020 EXPOWER project (@ExpowerEu). Bringing together 8 universities, 3 research institutes, 7 companies from 9 countries.

Another great achievement by @ehtelescope! Our new director @astroTui was involved as well, as a member of the #EHT team.

Every year on 4 May at 8 pm, our Westerbork telescope goes into a special mourning position to commemorate those who have fought for our freedom. This video, made together with @kampwesterbork, shows the dishes moving into position.

Our 'holy grail' has been found again! The #Kootwijk dish, which stood at the origin of ASTRON, has been located at @museumdeelen! The dish, originally a #Würzburg-Riese German radar dish, was the second telescope ever to detect the #hydrogen line.
