Earlier this year, #FRB 20190417A was pinpointed ⚡️ only the 4th repeating fast radio burst ever linked to a persistent radio source.
Now, three authors from @uva_api, @ASTRON_NL & JIVE interview each other on the discovery and how it was made.

🕳️✨ Erstes enges Paar extrem massereicher Schwarzer Löcher entdeckt 📡
Ein internationales Forschungsteam, an dem das Max-Planck-Institut für Radioastronomie beteiligt war, hat im Zentrum der Galaxie Markarian 501 etwas Außergewöhnliches gefunden: Es gibt Hinweise auf zwei supermassereiche Schwarze Löcher, die sich in einem extrem engen Orbit umeinander bewegen.
Beobachtungen über viele Jahre hinweg zeigen nicht nur einen, sondern gleich zwei Teilchenstrahlen (Jets), was ein starkes Indiz dafür ist, dass es sich um zwei „kosmische Giganten“ im letzten Stadium vor einer Verschmelzung handeln könnte.
Die beiden Schwarzen Löcher umrunden sich offenbar in nur rund 100 Tagen und könnten - kosmisch gesehen - schon in naher Zukunft miteinander verschmelzen. Dies ermöglicht einen seltenen Einblick in eine Phase, die bislang nur theoretisch vermutet wurde.🌌

🚨 Exciting New Science🚨
Could astronomers have finally found the key to solving one of the Universe's strangest mysteries?
In recent years, the emergence of a new class of objects known as Long-Period Transients (LPTs) has baffled radio astronomers. These bizarre objects emit powerful radio pulses every few minutes to hours - but their behaviour shouldn't really be possible according to our current understanding of how other objects, like pulsars, emit radio waves.
Now, a newly discovered white dwarf binary system may be providing the strongest clue yet. Some researchers are even describing it as a potential "Rosetta Stone" for understanding these mysterious objects.
I had a chat with PhD candidate Kovi Rose from the University of Sydney about this discovery, what makes this system so unusual, and how it could help unravel the mystery of LPTs.

Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest issue of Astronomy & Astrophysics.
📡☄️ Radio meteors, April 2026: volunteers in Kampenhout (BE) automatically counted meteor reflections on the VVS beacon at 49.99 MHz. Activity rose slightly, peaking on Apr 6; type III solar bursts were caught too (Apr 25). Lovely European grassroots radio astronomy.

📡 A radio-astronomy first: a CfA + NSF NRAO team has directly detected the imprint of interstellar turbulence on a distant quasar — TXS 2005+403. They re-analysed archival data from 10 VLBA antennas (2010–2019). Plasma in the Cygnus region distorts the radio image on scales the size of our Solar System. (May 22, 2026)

Astronomers led by the Center for Astrophysics | Harvard & Smithsonian (CfA) have made the first direct detection of turbulence distorting light in the interstellar medium. The findings will help scientists achieve clearer imaging of the supermassive black hole at the center of the Milky Way galaxy.
📡 The CARMELo radio meteor network recorded 21 radio echoes within 15 seconds of a brilliant fireball (mag −13) over the Tyrrhenian Sea on Apr 23, 2026. The network runs on SDR receivers with Raspberry Pi – citizen science radio astronomy in action. (Report May 7, 2026)
