New calibration technique circumvents Earth’s ionosphere
An international team of researchers has developed a new calibration technique to circumvent disturbances of Earth’s ionosphere.
ASTRON has turned 75!
75 years ago today, SRZM (Stichting Radiostraling van Zon en Melkweg/Netherlands Foundation for Radio Astronomy) was founded. This organization would later become ASTRON.

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).
Dwingeloo Telescope postcard 1955
© -
This postcard is probably from late 1955: it shows the finished Dwingeloo Telescope, but the area is still a construction site, far from ready for the official opening on 17 April 1956.
Part of the support structure for the dish during construction is still there, with a sign "Werkspoor Afd. Bruggenbouw" (bridge construction department).
A highlight of this photo is that it was taken during work on the feed. The antenna mast is down, someone (ir. Muller?) is seen up on the balcony of the telescope. The mast does not reach quite to the ground, so a platform is needed to reach it. The stairs to this platform are still part of the telescope today, although the mast has been replaced by a quadrupod.
The original postcard is in black and white, I colorized it with AI (and manual corrections).
