Imagine witnessing the breathtaking dance of the Northern Lights, a vibrant spectacle across the night sky. But what if I told you that the very source of this beauty, the sun, could also unleash chaos on Earth?
I'm talking about solar storms, those powerful eruptions from our sun that send charged particles hurtling through space. While they create the stunning aurora borealis, they also pose a significant threat to our modern world. These events are rare, but their potential to disrupt our lives is very real.
Solar storms can wreak havoc on critical infrastructure. Electricity grids, satellites, and even air travel are vulnerable to the effects of these cosmic outbursts. In fact, a recent incident involving an Airbus plane highlights just how quickly things can go wrong.
In October, over 6,000 planes were grounded due to a software issue. This was triggered by intense solar radiation, which caused a sudden drop in altitude for one of their planes. This prompted a necessary software update.
This is why scientists and governments worldwide are actively researching and preparing for these events. The UK government, for example, publishes the National Risk Register, which includes severe space weather among the serious hazards that could impact the country.
The Carrington Event of 1859 serves as a stark reminder of the potential impact of these storms. This event was the most intense geomagnetic storm in recorded history. It caused rapid fluctuations in the Earth's magnetic field, generating electricity in telegraph wires. Operators received electric shocks, and conversations continued even when batteries were disconnected.
Today, with our reliance on advanced technology, the effects of a similar event would be far more disruptive. Satellites are particularly vulnerable. Intense solar storms can cause the Earth's atmosphere to expand, increasing drag on satellites and potentially causing them to fall back to Earth. In February 2022, a solar storm led to the loss of 38 satellites.
But here's where it gets controversial... Orbital changes of satellites also increase the risk of collisions, and space weather can also wreak havoc on sensitive electronics, causing malfunctions. Radio communications can be severely impacted, with GPS systems potentially failing for days. This could lead to gridlock in cities as sat-navs fail, and it would also compromise the safe operation of airplanes.
Space weather has already been blamed for affecting aviation electronics. On October 30, 2025, a JetBlue Airlines Airbus A320 plane experienced a sudden altitude loss during a flight. The plane diverted to Florida, and 15 passengers were hospitalized. Investigations revealed that space weather corrupted data in a computer that controls the plane's flaps.
An Emergency Airworthiness Directive was issued, grounding more than 6,000 planes until a software update was installed. While this incident was serious, it could have been catastrophic. The directive stated that, in the worst-case scenario, an uncommanded elevator movement could exceed the aircraft's structural limits.
Electricity grids are also at risk. In March 1989, a space weather event caused a power outage in Quebec, Canada, leaving millions without power and heat for nine hours.
What are the chances of another Carrington event?
In July 2012, a Carrington-class event narrowly missed Earth. The sun rotates every 25 days, and fortunately, the active area was not pointed directly at us. However, researchers have found evidence suggesting that events could be even larger than the Carrington event. Miyake events, named after the scientist who discovered them, could pose a threat to modern society on a scale that is hard to comprehend. The last one was identified around a thousand years ago, so you could argue it's just a matter of time.
