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.

Super sharp images reveal a possible hypernebula powered by a source of fast radio bursts

A team led by astronomers in the Netherlands have confirmed a repeating FRB source to be linked to a potential ‘hypernebula’ – a dense and highly magnetised cloud of plasma that is illuminated by a powerful but still mysterious source.

Radio waves leaking from large satellite constellations could jeopardize astronomical exploration

The LOFAR radio telescope has shown that satellites can unintentionally emit radio waves that interfere with the observations of radio telescopes. Satellites circle the globe in ever increasing numbers. Their radio emission could, if not addressed, close unique and scientifically valuable windows into the Universe. It is of crucial importance for the astronomy sector and industry to collaborate to overcome these issues and for the International Telecommunications Union to establish regulation to control this emission.

I found this photo of Sinterklaas and one of his assistants in the archive of ASTRON. It contains no date, but the cars in the parking give an indication of the year this picture was taken - the date was presumably around 5 December.

Dame Jocelyn Bell Burnell public lecture

Wed 13 Dec 2023

We have the honour of welcoming Dame Jocelyn Bell Burnell to the Netherlands. On 13 December 2023, she will give a public lecture in Amsterdam at the Science Park. More information and the option to register for the lecture will follow soon. Recently, ASTRON announced the Bell Burnell Fellowship, named in honour, and with support […]
