A powerful geomagnetic storm from the Sun could one day do more than create beautiful northern lights — it could disrupt the internet, GPS systems, satellites and power grids that modern life depends on.
According to ZME Science, scientists are increasingly studying the risk posed by extreme solar storms, particularly events similar to the historic Carrington Event of 1859. That solar superstorm sparked fires in telegraph systems and caused widespread electrical disturbances long before the digital age. Today, experts fear the consequences could be far greater.
The concern centres on coronal mass ejections, huge bursts of magnetised plasma released by the Sun. When these eruptions slam into Earth’s magnetic field, they can generate powerful geomagnetic storms capable of disrupting communications infrastructure and electrical systems. Scientists warn that GPS navigation, satellites, aviation systems and parts of the internet could be affected.
Researchers have even coined the term “internet apocalypse” to describe a worst-case scenario where a severe solar storm damages critical infrastructure and causes large-scale outages lasting weeks or months. However, not all studies agree on the level of risk. Recent research suggests that while submarine internet cables may experience disruptions, they are unlikely to suffer catastrophic physical damage even during a once-in-a-century solar storm.
The warning comes as solar activity continues to rise. The U.S. National Oceanic and Atmospheric Administration recently issued a Strong Geomagnetic Storm Watch, highlighting the growing importance of monitoring space weather and preparing critical infrastructure for future events.
For now, there is no immediate threat of a global internet collapse. But scientists say governments, telecom operators and power companies should not wait for the next solar superstorm before strengthening their defenses. When it comes to space weather, the question may not be if another major event happens — but when.
