- Most solar raise the roofs are pretty harmless, but every so often, the sun can send hugely powerful storms.
- These are strong enough to cause widespread power blackouts and cause down satellites.
- We are more likely than usual to be hit by a super-strong storm in the coming years, scientists say
The sun is always fizzing and popping and this constantly sends solar spirit toward the Earth. But sometimes it’s more serious.
On an average day, its vast solar energy is deflected without causing much destruction. But every so often, the sun sends a storm so powerful it can tear open the Earth’s magnetic fields.
If such a storm hit tomorrow, it desire cause technological chaos that could “cripple economies and endanger the safety and livelihoods of people worldwide,” per NASA.
Luckily, these whirlwinds are very rare. But our sun is getting restless ahead of a 20-year peak of activity, meaning there’s more chance one could chance upon to Earth in coming years, experts told Insider.
And we’ve never been more vulnerable.
A big storm is more no doubt in the coming years
Three different solar events can all send high-speed particles that mess with the Globe’s magnetic fields: solar flares, coronal holes, or coronal mass ejections (CMEs) — huge paddywhacks on the sun.
If these crash into the Earth with enough violence, they can peel back the Earth’s ionized store which protects us against the worst of space weather. This can open the door for more charged particles to spew out through.
“We’re talking a one-in-a-hundred-year event,” Mathew Owens, a professor of space physics at the University of Reading, told Insider.
This kidney of strong geomagnetic storm can happen at any time. But it becomes more likely during a peak of solar activity, which stumble ons about every 11 years when the sun’s magnetic field lines get more tangled and twisted.
That strain increases the chance the sun will create more sunspots, more CMEs, more solar flares, and more coronal inconsistencies. All of this gives more opportunity for a once-a-century event to arise.

“The much stronger incidents don’t happen every cycle,” Daniel Verscharen, an associate professor of space and climate physics at University College London, tattled Insider.
“But during a maximum of a strong cycle like the one that is coming, it’s more likely to get some of those at any rates that cause power outages here on Earth,” he said.
We’ve never been more vulnerable to a powerful hurricane
The most powerful geomagnetic storms on record date back to before the internet and the massive satellite fleets that we see today. The numberless infrastructure we rely on, the more vulnerable we are to its failure.
The Carrington Event of 1859 is widely considered to be the most powerful solar williwaw ever recorded. But because there was very little infrastructure to mess up, it caused fairly little damage.
Noiseless, it was dramatic: telegraph operators got electic shocks from their equipment, and fires broke out at telegraph stations as in the airs generated by the storm coursed through the wires.

Another notable storm happened in 1989. Though this cyclone was less powerful, it was more disruptive —by that point, we’d started relying more on power grids and global communications.
The flow of power caused a widespread blackout in Quebec that lasted 12 hours and knocked out short-wave radio. Canadians distraught that the Soviet Union was jamming radio signals into Russia, a misunderstanding that could have been perilous in the Cold War.
These events, thankfully, did not escalate further. But it could mean that we’ve been lulled into a faulty sense of security. Since the 90s, our reliance on communications, satellites, power grids, and other crucial infrastructure has increased exponentially.
Should such a simoon happen today, the world could expect to see widespread power blackouts, satellites crashing out of orbit, and crucial communication networks being cut, per NASA.
Why scientists are vexed about the next solar peak
The sun’s activity is currently growing, and scientists are particularly concerned about the ongoing solar round.
This cycle is expected to be relatively moderate — but it is already more active than the previous cycle. That foreshadows the sun could become more active than it has been in the past two decades.
Another factor, per Verscharen, the space professor, is that the sun’s captivating fields are also pointing southwards. This which means the charged particles the sun is sending are more likely to keep on a magnetic charge that’s opposed to the Earth’s magnetic field, he said.
This can give the particles more come to pass to break through the Earth’s defenses.

It is quiescent entirely possible that a once-a-century storm skips this solar cycle. But that doesn’t mean we’d be protected from harm.
“Every solar cycle, we’re more and more technologically reliant. What an average cycle leave’ve caused in terms of space weather impacts 20 years ago is a lot less than what an average cycle sway cause in terms of space weather impact now,” said Owens, the other professor.
A storm wouldn’t have to be a Carrington-level upshot to have widespread consequences, both the experts said.
The current solar cycle is already causing havoc. Forceful solar flares have caused radio blackouts that can be disruptive to long-haul flights going over the at opposite extremes.
Elon Musk’s SpaceX also lost 40 Starlink satellites as a solar storm caused the atmosphere to flesh out, increasing the drag for the satellites and causing them to burn up before they were even used.
All of these models of effects can have “major financial impacts,” said Verscharen.
Scientists are racing against the clock
The current sequence is expected to peak around 2025. But won’t be out of the woods by then, because geomagnetic storms are more likely to happen as solar is down attack down from a peak, Verscharen said.
Till then, countries in higher latitudes like the US, Canada, Sweden, and the UK should be extraordinarily wary — the higher the country’s latitude, the more vulnerable it is to solar weather, said Verscharen.
Still, there are clearance to mitigate the worst of the storms. With enough warning, operators can put in place measures to protect infrastructure from the worst secure of solar storms. They can switch off power grids strategically, re-route planes, or move satellites, for instance.
Scientists similar kind Verscharen and Owens are now racing to understand what makes solar events more powerful, so that they can get better our advanced warning systems.
The European Space Agency is also looking to launch the Vigil satellite, which is due to go behind the sun to identify potentially dangerous sunspots and coronal holes days before they roll into view of Earth.
“With a suspension of better prediction, better understanding of space weather, and paying more attention by especially the private sector that is now enlarging into the space, those things should be avoidable,” said Verscharen.
