☀️ On 11 May 2026, an M5.8 flare erupted from AR4436 — within minutes HF radio across the Atlantic was knocked offline. A fast CME may glance Earth on 13 May (possible G1 storm, aurora reaching Scotland or Minneapolis). Neighboring AR4432 is also growing. Watch SWPC + spaceweather.com. 📅 May 11, 2026

🌌 An INAF-led team (A. Traficante) used ALMA to map the core mass function in the 30Dor-10 region of the Large Magellanic Cloud — the first time outside the Milky Way. Over 70 dense cores across 4 protoclusters at 0.05″ resolution. Star formation appears to follow universal laws. Published in Nature Communications. 📅 April 22, 2026

📡 Italian citizen-science network CARMELo (16 SDR receivers tuned to GRAVES 143.050 MHz) published its April 2026 report. Lyrids were weak this year, but the spectacular fireball over the Tyrrhenian Sea on April 23 (mag −13, 350 IMO reports) left 21 radio echoes within 15 seconds. Grass-roots radio astronomy at its best. 📅 May 7, 2026

☀️ Solar radio bursts reveal hidden magnetic "switchbacks" near the Sun. A study of 24 interplanetary type III bursts from Parker Solar Probe shows their variability is better explained by magnetic fluctuations than density changes. A beautiful result from open data! 📅 April 2026

🕳️ The Event Horizon Telescope team led by Paul Tiede (Harvard BHI) introduced a new technique — HIBI, hierarchical interferometric Bayesian imaging. Instead of building an image, it fits physical parameters directly from radio-interferometric data. Tested on M87* and promising for the future ngEHT and more distant black holes.

☄️ A radio view of an interstellar comet! ALMA measured 3I/ATLAS's HDO/H2O ratio — 30× richer in semi-heavy water than Solar System comets, 40× more than Earth's oceans. Data from 6 days after perihelion show it formed in a system far colder than ours. Nature Astronomy.

🎬 The Event Horizon Telescope launched a unique March–April 2026 campaign — its global VLBI radio-dish array images supermassive black hole M87* every 3 days. The aim: assemble the first ever "movie" of the rotating accretion disk and jet base at the event horizon. A leap forward in BH observation.
