Ascoltare lo spazio per segnali di intelligenze extraterrestri. Tutti in cerca di ET, i risultati preliminari della campagna crowd-souced di UC Berkeley per ventun anni di Seti@home. Dal 1999 al 2020 milioni di persone hanno messo a disposizione i loro computer per analizzare i segnali radio dell’Osservatorio di Arecibo alla ricerca di civiltà...

Abbiamo Intercettato una "Super-Civiltà". Un recente studio del telescopio CHIME raddoppia il numero di Fast Radio Burst ripetitivi conosciuti. E se non fossero stelle che esplodono, ma i motori di un’autostrada galattica?
Nello spazio profondo, qualcosa sta "urlando". Non una volta sola, come l'ultimo grido di una stella che muore, ma ripetutamente. Con costanza.

Understanding mysterious magnetars 🧲 and radio bursts 🌟 with gravitational waves
A flash of radio waves lasting a few thousandths of a second, as bright as millions or billions of stars, and it’s all over: even almost 20 years after their discovery, fast radio bursts remain one of the most mysterious phenomena in our Universe. Scientists believe that neutron stars – very small and extremely dense stellar remnants with huge magnetic fields – emit these bursts.
An international team has now used gravitational waves to study a nearby neutron star that has emitted several radio bursts. The researchers analyzed data from the German-British GEO600 detector to learn more about the origin of these events. Their results contribute to a better understanding of these extreme events and their theoretical description.
