☀️ 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

📡 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

📡 China's 500m FAST radio telescope discovered 6 new isolated millisecond pulsars in globular clusters NGC 6517 and NGC 7078. Known pulsar populations grow by ~27% and ~18% respectively. Faint, isolated pulsars are a great natural lab for neutron-star physics. (Apr 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.

📡 South Africa's MeerKAT radio telescope mapped 115 galaxy clusters and found 103 diffuse radio emissions – 60 never seen before! The MGCLS II catalogue (Rhodes Univ. & SARAO, led by K. Kolokythas) reveals energetic processes in the spaces between galaxies, visible only in radio. A stunning preview of what the full SKA will deliver.

🌋 A supermassive black hole in galaxy J1007+3540 has reawakened after ~100 million years of silence! LOFAR (Netherlands) & uGMRT (India) radio telescopes captured fresh jets slamming into the hot gas of the surrounding galaxy cluster, bending into a plasma flow nearly 1 million light-years long. Published in MNRAS.

🔭 China's SYISR–FAST bistatic radar mapped the lunar south pole! Sanya radar transmitted at 430 MHz while the giant 500m FAST radio telescope received echoes. Result: surface water ice content at the south pole is max 0–6 wt% – ice is likely buried deep below the surface. Key data for future Artemis & Chang'e-7 missions.

📡 The hunt for dark matter begins! University of Virginia installed a 5m radio telescope at Fan Mountain Observatory. It searches for axions — hypothetical dark matter particles — using neutron stars as cosmic traps. The intense magnetic fields of pulsars should convert axions into detectable radio signals.

✨ An engineering marvel from the 1970s! 🚀
Construction began in 1967, with 40–60 people working on the project for a total of 1,318 days. On an area of 154,000 m², the radio telescope with its 100 m diameter dish was built – including laboratory and office buildings as well as the control room. 🏗️🔧 The ground had to support a load of 3,200 tons! 💪🗓️ Milestones:
1966: Foundation of the institute
1967–1971: Construction of the Effelsberg radio telescope
May 1971: Inauguration of the radio telescope 🎉
August 1972: Start of scientific operations 📡🔭 Today, it is the second-largest fully steerable radio telescope in the world! 🌍

Während heute Astronauten von der ISS zur Erde zurückkehren, funkt die Raumstation ständig mit Bodenstationen. Für Radioastronomen ist die ISS damit eine der hellsten künstlichen Radioquellen am Himmel.
📻 Über das ARISS-Programm hatten Schulklassen weltweit die Möglichkeit, direkt mit Astronautinnen und Astronauten auf der ISS zu sprechen – per Funk. Möglich wurde das nur durch die Unterstützung engagierter Funkamateure, die die Funktechnik bereitstellten, Kontakte koordinierten und die Kommunikation technisch absicherten.
🔬 Am MPIfR erforschen wir dagegen das extrem leise Universum. Dafür entwickeln wir Methoden, um solche starken Funksignale zu erkennen, zu filtern und zu vermeiden. Deshalb stehen Radioteleskope in geschützten Regionen – etwa in der Eifel, in Wüsten oder Hochgebirgen.
🌍 Der Weltraum ist nämlich radio-laut, nicht radio-leise: Gerade in Erdnähe erzeugen Satelliten, Raumsonden und Bodenstationen einen dichten „Funknebel“.
