📡 For the first time the ITU-R EPFD regulatory framework has been applied directly to radio telescope measurements. All-sky interferometric data show unintended emission from satellite mega-constellations exceeding the radio astronomy interference threshold in 50–70% of samples — against a 2% tolerance. Margins are negative: −18.6 to −16.3 dB. Preprint, 2 Sep 2026.

📡 Images from the Radio Galaxy Zoo citizen science project were used to pretrain very small vision models (~6M parameters) with LeJEPA. A University of Geneva team shows that self-supervised learning directly on radio astronomy data matches far larger models at radio galaxy morphology classification — cheaper and more scalable. Preprint, 31 Aug 2026.

☀️ Solar radio astronomy, seen from Czechia: Dr Miroslav Bárta of the Solar Department at the Astronomical Institute of the Czech Academy of Sciences explains what ALMA in the Chilean Andes reveals about our nearest star, what Czech researchers focus on, and which upgrades will sharpen observations for other fields too. (In Czech.)

📡 The MIDAS survey is the deepest MWA map so far — the GAMA9 and GAMA23 fields at 215.7 MHz. Over 2,100 deg² of sky, nearly 100 hours of observing and a catalogue of 133,826 radio components above 5σ. Mosaics, RMS maps, catalogues and the full imaging pipeline are all released publicly.

📻 Radio meteors, August 2026: Felix Verbelen's monthly report of reflections recorded at Kampenhout (BE) on the VVS beacon frequency of 49.99 MHz. The Perseids peaked on 13 Aug; 52 reflections lasting over a minute were logged across the month. Raw hourly counts are published as CSV, ready for your own analysis.
