The Joint VLBI School (JVS) 2025 (15-19 Sep 2025) will take place simultaneously at JIVE in Dwingeloo (NL) and the University of Pretoria (SA). Online attendance will also be available for lectures and expert Q&A, though hands-on sessions will primarily be held on-site. Aimed at students and professionals in radio astronomy, JVS 2025 offers in-depth [...]
ASTRON has joined the Breakthrough Listen projects to enhance the search for technosignatures—potential signs of extraterrestrial intelligence—through the use of the Westerbork Synthesis Radio Telescope (WSRT). This collaboration marks a significant step forward in monitoring the radio sky. With the Westerbork Telescope now fully integrated into the project, the team can continuously monitor the entire [...]

This issue highlights a range of significant scientific achievements, showcasing the breadth and vitality of our community. [Read more here]
Sweden and the United Kingdom have officially joined LOFAR ERIC (European Research Infrastructure Consortium) as full members, following a Council decision on 26 March 2025. This brings the consortium’s total membership to eight countries, marking a major milestone in the growth of Europe’s premier low-frequency radio astronomy network. Both countries have been long-standing collaborators, hosting [...]
The European VLBI Network (EVN) is an international array of radio telescopes in Europe, Asia, and South Africa, delivering ultra-sensitive radio images at (sub-)milliarcsecond resolution. The EVN is open to all astronomers, though restrictions currently apply to PIs and co-Is affiliated with institutions in the Russian Federation or Belarus. Proposals from students and those with [...]
