On 15 May 2025, Onsala Space Observatory celebrated 75 years of groundbreaking science and innovation. As Sweden’s national facility for radio astronomy, Onsala has been at the forefront of global efforts to explore the universe and understand our planet. Since its founding in 1949, Onsala has contributed to major scientific advances in astronomy, geodesy, and [...]
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 [...]
The new edition of the EVN newsletter has been published, featuring a welcome message from Krzysztof Katarzyński (Nicolaus Copernicus University, Toruń, Poland), newly nominated Chair of the EVN CBD for a two-year term. 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 [...]
IVTW2025 will take place October 21-25, 2025. The meeting will be hosted by Chalmers University of Technology, Onsala Space Observatory, in Gothenburg, Sweden. The scope of the workshop is to encompass all areas of VLBI hardware and software development and techniques on station updates, frontends, backends, recorders, correlation, image processing, potential space VLBI missions and [...]
The SFXC workshop is aimed at individuals interested in using the Super FX Correlator ("SFXC") for software correlation of data from their own VLBI instruments (or other long-ish baseline radio interferometers), as well as scientists who want to exploit SFXC's advanced features by doing their own correlation. The workshop will take place over of two [...]
Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair. The surprise discovery was made using the European Southern Observatory’s Very Large Telescope (VLT). Read more. [...]
Most stars form in molecular clusters, with specific environmental conditions dictating how planetary systems develop. Nearby massive stars can also influence by intense ionizing radiation, which can create a shell of ionized gas around a protoplanetary disk and emit unique hydrogen recombination spectral lines. Recently a scientific team led by Ryan Boyden/University of Virginia has [...]
The European Commission has launched two consultations on the future European Strategy for Artificial Intelligence in Science: a Call for Evidence, and a targeted questionnaire for researchers and the broader research and innovation community. The strategy will aim at accelerating the responsible use of Artificial Intelligence. Everyone interested can contribute to the Call for Evidence. Researchers and [...]
