Nasa warns of huge solar flares causing blackouts on Earth

Опис:

Astronomers are warning of increased solar storms in the coming days as a highly active sunspot region rotates to face Earth. NASA recently recorded 2025’s strongest solar flare so far—an X2.7-class eruption—which caused brief radio blackouts in the Middle East. More flares and coronal mass ejections (CMEs) from this region could disrupt radio signals, power grids, navigation systems, and pose risks to satellites and astronauts. The Sun is currently at its solar maximum, the peak of its 11-year activity cycle, the Independent has reported. The heightened activity may also bring spectacular auroras as charged particles reach Earth’s atmosphere.
