Telescopes

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

Astronomy

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.

Beschermingszones


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).

Telescope quartet reveals surprising statistics of cosmic flashes

Scientists led by Chalmers astronomer Franz Kirsten have studied a famous source of repeating fast radio bursts – a still unexplained cosmic phenomenon. Comparing with earlier measurements, the scientists draw a conclusion with far-reaching consequences: any source of fast radio bursts will repeat, if watched long enough and carefully enough. The research team, a unique collaboration between professional and amateur radio astronomers, used four telescopes in northern Europe, amongst which ASTRON’s Westerbork Synthesis Radio Telescope.

Dutch astronomers prove last piece of gas feedback-feeding loop of black hole

Three astronomers from the Netherlands have proven that gas that was previously heated near a supermassive black hole and flowed to the outskirts of the galaxy and cooled down, is moving back towards the black hole. While there had been indirect evidence for this theory, this is the first time that the cooled gas moving toward the black hole has actually been observed.

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.

Pushing Limits

© FHI

On Friday 2 February 2024 our "own" André Gunst took the stage in Ahoy Rotterdam to inspire an audience of ~600 people with the fascinating journey we are undertaking. He explained how we unveil the mysteries of the Universe by pushing the limits of technology. In his talk he explained how we make discoveries in radio astronomy happen, our mission.

The event "TechStories" was organised by FHI (Federatie Het Instrument), which is a federation of technology branches (www.fhi.nl). The goal of FHI was to organize an inspiring tech event about groundbreaking technologies.

André was happy he participated: "During the preparation and before the event I felt a very thin line between on the one hand tension and on the other hand excitement. I was very much looking forward to it, but at some times I thought: why am I doing this... After the talk I felt pride. Pride in what we, at ASTRON (and JIVE/NOVA of course), are doing but also pride that opportunities like these pass by which help me stretch my comfort zone. So the talk was about pushing the limits of radio astronomy and technology, but the experience led me to push the limits of my own comfort zone. What's next?"
