Solar storms that cause the Northern Lights can also harm Earth’s technology. Charged particles from the Sun create dazzling auroras. But they can disrupt satellites, air travel, and electricity supplies. Recently, Airbus grounded 6,000 planes after one suddenly lost altitude in October, linked to solar radiation. The UK government warns about severe space weather risks, alongside nuclear incidents and disease. The largest recorded storm, the 1859 Carrington Event, caused telegraph sparks and shocks. Today, similar storms could cause far worse damage because of advanced technology. Satellites can slow, fall, or malfunction. In February 2022, 38 satellites were lost due to a solar storm. Radio and GPS can fail, affecting cars and planes. Space weather caused a JetBlue Airbus A320 to suddenly drop altitude in 2025, injuring 15 passengers and forcing an emergency software fix on 6,000 planes. Power grids can also fail, as happened in Quebec in 1989, leaving millions without electricity for hours. Another Carrington-class event nearly hit Earth in 2012 but missed. Scientists warn we may face even stronger events, called Miyake events, much bigger and rare. These could threaten modern society, and with one last seen about 1,000 years ago, it may be only a matter of time.
