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.

ASTRON is the Netherlands Institute for Radio Astronomy, and is part of the Institutes organisation of NWO.
Astronomers discuss future of Space VLBI in Dwingeloo

On 17-19 October 2022, JIVE and ASTRON co-hosted the 3rd Next Generation VLBI workshop (ngSVLBI-3) in Dwingeloo, the Netherlands. The hybrid workshop was attended both in-person and remotely by about ninety participants from all over the world.

LOFAR detects gigantic radio sources in the universe

An international research team has discovered four radio sources of up to ten million light years in size: megahalos.

People of ASTRON: Fanna Lautenbach

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? Software engineer Fanna Lautenbach studied both astronomy and computer science and found her perfect working place here at ASTRON.

ERIS 2022 School inspires next generation of radio astronomers

Over 70 students from all over the world participated in the 9th European Radio Interferometry School (ERIS 2022) hosted by JIVE and ASTRON in Dwingeloo (the Netherlands) on 19-23 September 2022.

ESCAPE ESAP Training Workshop

© ASTRON & ESCAPE Partners

ESCAPE is a multi-national Horizon 2020 project to develop common “e-infrastructure” solutions — data storage, software repositories, analysis systems, and so on — which are applicable across a range of major European research facilities.

While ASTRON has made contributions across a wide range of activities within ESCAPE, one of our major roles has been leading the development of ESAP, the project's science analysis platform toolkit. ESAP provides tools to help scientists access and analyze data from a variety of sources quickly and easily. Rather than being a one-size-fits-all solution, the idea is that different projects and facilities can build on the ESAP system to quickly put together a platform that suits the needs of their particular user community.

On 21 & 22 November, we organized an ESAP Training Workshop, at which the development team introduced their work to a range of different research infrastructures and other service providers that we hope might benefit from deploying services based on the ESAP toolkit. Across a range of talks and discussion sessions, ESCAPE partners from around Europe presented a comprehensive overview of what ESAP can do — and the feedback from the workshop participants was overwhelmingly positive.

The image shows a range of figures and diagrams taken from the talks at the workshop. We hope these are enough to whet your appetite — for the full story, all the slide decks and videos of the complete event are available from the website at

ESCAPE will conclude in January 2023, but the ASTRON team plans to continue building on the technologies it developed in our work for LOFAR and SKA, and with our partners in other institutions across the continent.
