Un vortice luminoso nel cielo. È quello che si è potuto osservare per pochi minuti questa sera attorno alle 21.10 nei cieli di mezza Europa: segnalazioni arrivano dal Nord Italia, Francia, Germania e Regno Unito.
Non si tratta di alieni o altri fenomeni misteriosi: come riporta il sito specializzato in astrofisica Chpdb, quanto osservato è un effetto creato da un Falcon 9 di SpaceX che ha liberato il carburante avanzato.
Il lancio della missione NROL69 è avvenuto alle 18:48 da Cape Canaveral, in Florida. Con la sua orbita successiva, il razzo ha sorvolato il continente europeo e grazie alla scarsa copertura nuvolosa, l’insolita spirale si è presentata agli occhi di molti.
Il fenomeno non è nuovo agli appassionati, e serve a preparare il rientro atmosferico del razzo nel Pacifico meridionale.
