Earth has been rocked by the first extreme geomagnetic storm in two decades, creating a spectacular light show in UK skies and other parts of the Northern Hemisphere – but also posing a threat to communication networks, navigation systems and power grids.
Elon Musk’s Starlink, which owns around 60% of the estimated 7,500 satellites currently in orbit, providing internet coverage around the world, has warned of a “degraded service” as a result of the phenomena.

It was the first G5 or strongest rated geomagnetic storm since 2003, which caused blackouts in Sweden and damaged transformers in South Africa.
So what caused the extreme geomagnetic storm?
A series of strong solar flares spewed from the Sun’s surface have sent a shockwave of magnetically charged plasma directly at the Earth, known as coronal mass ejections (CMEs).
The resulting collision has caused a major disturbance to our own planet’s magnetic field.
Does it pose a threat?
As well as producing extended vivid displays of colour across the skies in places the aurora borealis or Northern Lights cannot usually be seen, as witnessed in southern England, severe solar storms can also disrupt everyday communication and navigation systems.
The Sun’s energy has a direct impact on the Earth’s ionosphere, where the planet’s atmosphere meets space.
Changing conditions can affect satellites by increasing drag, while radio and GPS signals that travel through this layer of the atmosphere or rely on bouncing off it can also be disrupted.
Severe solar storms can also create harmful geomagnetic induced currents in the power grid, leading to blackouts.

Northern Lights from around the world
The largest known geomagnetic event in history, known as the Carrington Event of 1859, caused telegraph machines to spark and catch fire.
How likely is it we will see the Northern Lights above the UK tonight?
Sky News weather presenter Kirsty McCabe, says: “There is a chance – but it’s not as likely as last night so unlikely to be as bright or seen as far south.
“America’s National Oceanic and Atmospheric Administration (NOAA) classed Friday night’s solar storm as an extreme G5 – the highest level and first observed since 2003.

“Saturday night will probably be more like a strong G3.
“You might not be able to see it with the naked eye but use a long exposure on your camera phone and you may be pleasantly surprised. Remember to look north.”
What could prevent it from being seen again?

McCabe says: “You might not be in the right place, northern parts of the UK have a better chance than those further south.
“Plus, light pollution from cities could also spoil your view.
“And of course, the weather needs to play its part – if the skies aren’t clear you won’t see the aurora.
“For many places the weather conditions are looking good, plus it is mild overnight.”
Where is it most likely and between what times?

McCabe says: “The best time to spot them is between 10pm and 2am, so you’ll need to wait until it’s dark.
“Keep an eye on social media for any sightings near you and on UK aurora watch sites.
“The Northern Lights are most likely across Scotland, but as with last night, it is possible to see them further south if the solar activity is strong enough.
The UK lacks a national plan to defend itself from attack and is moving at a “glacial” pace to fix the problem despite threats from Russia and China, a report by MPs has warned.
With the whole country needing to understand what it means to be ready for war, the Defence Select Committee also said it had seen no sign of a promised “national conversation on defence and security” that was launched by Sir Keir Starmer in June.
Sky News and other journalists were even blocked on Monday from interviewing sailors aboard HMS Prince of Wales, the Royal Navy’s flagship aircraft carrier, in direct contrast to the prime minister’s stated aim of greater engagement.

Public needs to know ‘what to expect’ from war
“We have repeatedly heard concerns about the UK’s ability to defend itself from attack,” said Labour MP Tan Dhesi, chair of the committee.
“Government must be willing to grasp the nettle and prioritise homeland defence and resilience.
“In achieving this, government cannot shy away from direct engagement with the public.
“Wars aren’t won just by generals, but by the whole of the population getting behind the Armed Forces and playing our part.
“There needs to be a co-ordinated effort to communicate with the public on the level of threat we face and what to expect in the event of conflict.”

‘The Wargame’ made real?
The findings of the report support a podcast series by Sky News and Tortoise Media called The Wargame – released in June.
It simulated a Russian attack on the UK and played out what the impact might be for the country in the absence of a credible, resourced and rehearsed national defence plan – something Britain maintained rigorously during the Cold War.

Flagship aircraft carrier to be placed under NATO command
Report’s assessment of war-readiness
The Defence Select Committee report – based on a nearly year-long inquiry – found: “The UK lacks a plan for defending the homeland and overseas territories with little progress on the Home Defence Programme.”
It said this meant the government was failing to meet a fundamental commitment to the NATO alliance – the Article 3 requirement to maintain the “capacity to resist armed attack”.
The report quoted Luke Pollard, a defence minister, acknowledging that “we have been very clear that we are not satisfied with Article 3 in the UK”.

Yet the MPs’ report added: “Despite this recognition from government… measures to remediate seem to be moving at a glacial pace.”
It said: “Cross-government working on homeland defence and resilience is nowhere near where it needs to be. The government has said repeatedly that we are in an era of new threat, yet decision-making is slow and opaque.”
The rebuke from the MPs was published as John Healey, the defence secretary, prepares to announce that 13 sites across the UK have been identified as possible locations for at least six new weapons factories.
“This is a new era of threat,” he will say at a speech in Westminster later.
“We are making defence an engine for growth, unambiguously backing British jobs and British skills as we make the UK better ready to fight and better able to deter future conflicts.
“This is the path that delivers national and economic security.”
Industry will be invited to submit proposals to produce ammunition and explosives, with the Ministry of Defence saying it hopes work on the first factory will begin next year.
Ultra-processed foods (UPFs) are a leading cause of a “chronic disease pandemic” linked to worsening diets, experts have warned.
UPFs include items such as processed meats, some ready meals and cereals, ice cream, crisps, biscuits, mass-produced bread and fizzy drinks.
They often contain a high level of saturated fat, salt and sugar – as well as additives such as sweeteners and preservatives.
UPFs leave less room for more nutritious foods and are also believed to negatively affect gut health.
Forty-three scientists and researchers have now sounded the alarm and accused food companies of putting “profitability above all else”.
Writing in The Lancet, they said the firms’ economic and political power is growing and “the global public health response is still nascent, akin to where the tobacco control movement was decades ago”.
They warned that while some countries have brought in controls on UPFs, policy is lagging due to “co-ordinated efforts of the industry to skew decision-making, frame policy debates in their interest, and manufacture the appearance of scientific doubt”.
Professor Chris Van Tulleken, from University College London, one of the authors, said obesity and diet-related disease had increased in line with a “three-decade history of reformulation by the food industry”.
“This is not a product level discussion. The entire diet is being ultra-processed,” he warned.
However, several experts not involved with the article urged more research, cautioning that existing studies had shown a link with poor health and UPFs but not established causation.
Kate Halliwell, chief scientific officer at the Food and Drink Federation (FDF), which represents the industry, said companies had made a “series of changes over many years to make the food and drink we all buy healthier, in line with government guidelines”.
She said FDF-member products now contained a third less salt and sugar and a quarter fewer calories than in 2015.
A 2023 meta analysis in the PubMed journal said evidence suggested an association between UPF intake “and the risk of overall and several cancers, including colorectal, breast and pancreatic cancer”.
Get cancer symptoms checked, charity urges
It comes as Cancer Research UK warned too many Britons are putting off getting potential symptoms checked.
A poll for the charity suggested the top reasons people delay getting potential signs of cancer checked is because of a lack of GP appointments, or thinking their symptoms might not be serious.
More than half (53%) of the 6,844 surveyed said they were put off as they believed getting seen would be difficult, while 47% said they actually had found it difficult to get an appointment.
Some 44% put it off as they though the symptom wasn’t serious, 41% believed they could manage things themselves, and 40% didn’t want to be seen as making a fuss.
Cancer Research UK said it had now trained Tesco pharmacists to spot possible cancer signs – and that people can speak to them in private if they needed.
The pharmacists will be able to give advice on next steps and whether a GP appointment is recommended.
Scotland secured a place at the men’s World Cup for the first time since 1998 as stoppage-time goals by Kieran Tierney and Kenny McLean secured a thrilling 4-2 win over Denmark at Hampden Park.
Scott McTominay’s spectacular third-minute bicycle kick had given the hosts a half-time lead.
Rasmus Hojlund equalised for the Danes in the 57th minute shortly before Rasmus Kristensen was sent off, but Lawrence Shankland restored Scotland’s advantage.
When Patrick Dorgu brought Denmark level again with nine minutes remaining, it seemed they would claim the point needed to top the group and book their place at next year’s tournament in the US, Canada, and Mexico.
However, Tierney fired an unstoppable shot past Kasper Schmeichel in the third minute of stoppage time
And then, with the Denmark goalkeeper up in attack at the other end of the pitch, McLean hit a long-range effort from his own half to spark delirious scenes.

He told the BBC: “We certainly put the country through it, but I’m sure it will be worth it.”
“I couldn’t get my mate Diogo Jota out of my head today,” he added. We spoke so much together about the World Cup. When he missed out in Qatar through injury and I missed out when Scotland never went.
“We always discussed what it would be like going to this World Cup. I know he’ll be somewhere smiling over me tonight.”
The draw for the 2026 World Cup will take place in Washington on 5 December.
