Starquakes: The Birth of Cosmic Radio Signals ⚡ экспресс
Original: "Crustal Quakes Spark Magnetospheric Blasts: Imprints of Realistic Magnetar Crust Oscillations on the Fast Radio Burst Signal"
For the first time, simulations show how the shaking of a magnetar's crust gives rise to powerful bursts of radio emission.

A dead star the size of a city suddenly quakes — and its magnetic field ripples like a drum skin. The oscillations turn into beams of particles racing at nearly light speed. We catch them as mysterious radio bursts from distant space. For the first time, scientists traced the entire path — from a crack in the crust to the flash.
🎯 A magnetar's magnetic field is billions of times stronger than Earth's. If it were at the Moon's distance, not just cards but any magnetic recording would fly.
🎬 In Carl Sagan's 'Contact,' the alien signal turned out to be a message; fast radio bursts were also initially mistaken for greetings from extraterrestrial civilizations.
