Tempesta geomagnetica scatena aurore in Messico
Riportato dall'IA Immagine generata dall'IA
Una severa tempesta geomagnetica, innescata da un'espulsione di massa coronale solare, ha illuminato i cieli con aurore boreali in Messico e nell'emisfero settentrionale l'11 novembre 2025. Immagini di colori verdi e viola sono state catturate in stati come Zacatecas e Nuevo León, mentre negli Stati Uniti sono state viste in Colorado e Kansas. Esperti di UNAM e NOAA indicano che gli effetti continueranno più debolmente il 12 novembre e possibilmente il 13.
New data from the European Space Agency's Swarm satellites reveal that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has grown by nearly half the size of continental Europe since 2014. A region southwest of Africa is weakening even faster in recent years. This expansion highlights unusual activity in Earth's molten outer core.

Researchers at Kyoto University have suggested a possible connection between solar flares and earthquakes through ionospheric disturbances. Their theoretical model indicates that electrostatic forces from space weather could influence stressed fault zones in Earth's crust. The study does not claim direct causation but highlights a potential interaction mechanism.
