🎬 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.

📡 NASA's CANVAS CubeSat is live! The 4U CubeSat from CU Boulder has started its mission to study very low frequency (VLF) radio waves in Earth's magnetosphere — waves that can knock electrons out of the radiation belts. The data will sharpen space-weather models. (16 Apr 2026)

📡 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.

I dati HETDEX rivelano un vasto “mare di luce” tra le prime galassie
Gli astronomi del Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) hanno utilizzato i dati del progetto per realizzare la più grande e accurata mappa tridimensionale finora ottenuta della luce emessa dall’idrogeno eccitato nell’universo primordiale, tra 9 e 11 miliardi di anni fa.

From Yashwant Gupta, "Phased Arrays":
"For identical elements, this phased array gives a sensitivity which is n times the sensitivity of a single element, for point source observations. The beam of such a phased array is much narrower than that of the individual elements, as it is the process of adding the voltage signals with different phases from the different elements that produces the narrow beam of the array pattern."

✨ 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! 🌍
