Scientists issue urgent warning over solar storm poised to cause global blackouts and travel chaos: 'We're not prepared'
Scientists have warned that humanity is not prepared for extreme space weather as a solar storm is predicted to smash into Earth this week.
They conducted a 'solar storm emergency drill ', simulating what would happen if a major geomagnetic storm hit Earth.
Results showed power grids failed, blackouts were triggered and communication broke down across the US.
The exercise ran four simulations of geomagnetic storms of different severities, which is is a temporary disturbance of Earth's magnetic field caused by a massive eruption of charged plasma from the sun's outermost layer.
One scenario included a 'solar superstorm', strong enough cause an 'internet apocalypse,' resulting in power grid disruptions across the entire US with the eastern seaboard experiencing blackouts, which lasted for weeks.
Not only were power grids impacted, but railways and pipelines were also knocked offline, causing mass disruptions of travel and dramatic price increases of gas.
Scientists are now calling for a whole-of-government planning approach, arguing it will be critical for protecting America from cosmic disaster.
That would include deploying more satellites to monitor space weather, enhance real-time data collection to improve forecasting models, and provide earlier warnings.
The report comes as NASA warns a massive solar storm is heading toward Earth this week, which could turn the simulations into a reality.
The imminent solar storm is the result of a powerful X-class flare, which could trigger the event simulated in the exercise.
These are the most powerful solar flares, and they often coincide with coronal mass ejections (CMEs), which are large eruptions of plasma and magnetic fields.
The sun has unleashed powerful streams of energized particles several times in the past few days with the most recent on May 19.
NASA warned that more is to come, saying the bursts could continue to impact 'radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts '.
The latest exercise was conducted in May 2024 by the Space Weather Operations, Research, and Mitigation (SWORM) task force, which includes agencies like the National Oceanic and Atmospheric Administration (NOAA) and the Department of Homeland Security (DHS).
The fictional scenario was set on January 29, 2028, and involved a series of massive solar flares and high-energy radiation from the sun aimed at Earth.
Solar flares are intense bursts of radiation that come from sunspots — darker, cooler areas on the sun's surface — and are among the most powerful explosions in the solar system. These flares can last from a few minutes to several hours.
The drill tasked scientists with tracking an active solar region rotating toward Earth, testing protocols and response times in the face of a potentially catastrophic solar storm.
In the simulation, the solar activity disrupted critical systems such as damaging satellites and knocking out power grids across the US.
Scientists observed intense radiation exposure to satellites, astronauts and commercial aviation, and radio communications outages and disruptions.
Participants identified the greatest challenge was forecasting impact of a coronal mass ejection (CME)—a massive burst of plasma and magnetic field from the sun.
The current technology could only detect a CME about 30 minutes before it reaches Earth, when the magnetic orientation becomes clear, which makes preparation impossible.
The report recommends investing in advanced space weather satellites, deploying more sensors to monitor solar activity, and increasing cooperation between US. agencies, international allies, and private industry.
'Ongoing preparedness efforts for a space weather event are crucial because an extreme event has the potential to severely impact our nation's critical infrastructure and threaten our national security,' the report stated.
'Just as we prepare for earthquakes, hurricanes, and cyberattacks, our nation must take action before a major space weather event occurs.'
Coincidentally, the exercise was conducted at the same time the Gannon Storm, Earth's most powerful solar storm in two decades, hit on May 10, 2024.
That storm triggered a mass satellite migration, temporarily making Earth's orbit unsafe, and caused local power outages as well as widespread radio and satellite communication blackouts.
Now, a year later, NASA issued the warning after a powerful burst of energy from the sun on May 14, which measured as an X2.7-class solar flare, the highest category for solar flares and coronal mass ejections (CMEs).
The flare has caused radio blackouts across Europe, Asia, and the Middle East, along with some power degradation in the eastern US. But the space agency suggested more are to come.
While NASA warned more blackouts and communication interference are expected in a matter of days, the agency also noted that several US states will witness stunning northern lights.
Those include Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Michigan, Wisconsin, and Maine, as well as parts of nearby states, including New York.
Solar flares are grouped into five categories: A, B, C, M, and X, with each level representing a tenfold increase in energy output. A is the weakest, and X is the strongest.
The UK's Met Office reported that up to five sunspot regions are currently visible on the side of the sun facing Earth, with a new magnetically active region rotating into view over the southeastern solar horizon.
The agency also noted that a region near the sun's northwest limb may have produced a moderate-class flare earlier on May 19.
'Solar activity is expected to remain mostly low, but with an ongoing chance of isolated moderate-class flares,' the Met Office added.
This uptick in solar activity highlights the importance of monitoring space weather, especially as our society becomes more reliant on technology.
As the sun continues through its active phase, more solar flares and potential geomagnetic storms could occur in the coming days and weeks.

What we can see in the sky this coming week
Noctilucent clouds, (NLCs), make for an interesting spectacle after sunset, observable with the naked eye and quite eerie in appearance. Around two hours after the Sun has set and looking above the northwest horizon, watch for wispy threads of cloud with a distinct blue and silver tinge to them. Taken from the Latin for 'night-shining', NLCs are formed by sunlight reflecting off high-altitude ice crystals that are positioned right on the edge of space. The time period after sunset is crucial if we are to catch NLCs, as around 90 minutes to two hours after the Sun has dipped below the horizon is when the necessary angle occurs for sunlight to catch the crystals and illuminate that part of the sky with this enchanting effect. The beautiful and captivating sight sees the highest clouds in our atmosphere, about 50 miles above the Earth's surface, seem to glow and shimmer with this mesmerizing blue or silvery guise. In the summertime the mesosphere, (the third layer of the Earth's atmosphere where meteorites burn up), becomes cold enough to allow ice to form on suspended dust particles that are floating around in the clouds. These particles may originate from meteorites falling from space, but equally so from other sources, possible volcanic, with the recent Mount Etna eruption billowing tons of debris into the atmosphere. In fact, the first NLCs observations were recorded in 1885, two years after the eruption of Krakatoa, which may or may not have something to do with their appearance. Eruptions aside, rockets that have blasted off from Earth leave particle emissions from their exhaust systems, all contributing to the array of debris circulating in our atmosphere. NLC's have been given a different name when seen from space looking back on Earth; polar mesospheric clouds, or (PMCs). However, the Earth is not the only place NLC's have been witnessed. Launched in June 2003, Mars Express was not only the first European mission to Mars, but the first planetary mission operated entirely by Europe. There were reports of NLC's made three years into the Mars Express mission in 2006, with NASA's Curiosity Mars rover confirming the presence of NLC's in 2019. Readers may well recall all the media hype over Asteroid 2024 YR4, which earlier this year was once considered the highest impact risk to Earth ever recorded. Earlier this week, NASA announced that previously collected data on the asteroid that has been reanalysed now reveals that the 174 to 220 feet-long chunk of rock is more likely to hit the Moon in 2032. During the week ahead, watch for Mars in the evening sky as it moves its way slowly night by night, left to right, above the bright star Regulus in the constellation of Leo, the Lion, situated above the western horizon. The International Space Station continues its early summer break and cannot be seen across our region at present. Send your astrophotography pictures to: thenightsky@

What are rare earth elements and why are they important?
So-called rare earth elements refer to 17 chemically-similar, silvery-white elements that are used to make magnets – which in turn power motion for electric vehicles, cell phones, missile systems and other electronics. But how critical are they, and are they actually rare? Eric Onstad explains.

A Nazi rebranded as a Space Race hero – but you probably knew that already
Nasa, Nazis and the Space Race (Channel 4) is a strong, if misleadingly titled, one-off documentary. It tells the story of Operation Paperclip, one of the most controversial operations of the 20th century in which 1,600 former Nazi scientists were pardoned at the end of the war and then taken to the USA. There they were recruited to develop rockets, both for weapons and later space flight. In the meantime their reputations and history were conveniently whitewashed in the service of a new moral imperative: defeating the Russians in the space race. The film's title is misleading, however, because it quickly becomes apparent that this is really another chapter in the Wernher von Braun story. Von Braun was a member of the SS who worked under the Nazi regime and developed the V-2 rocket. How and why his past was forgotten and he was allowed to rebrand himself as an all-American hero – a space visionary rather than a war criminal – soon becomes the main point of interest in Nasa, Nazis and the Space Race. You can see why all the iron filings cling to Von Braun: his story is revealing and disconcerting, and here it is very well told. In the age of Netflix documentary series that go on forever and use all the bells and whistles as padding, a straight-down-the-lens history using only expert testimony and archive footage is intellectual balm. Splicing in Super-8 films of can-do, Roger Ramjet America in the 60s makes for great television. Von Braun himself, with his Aryan visage and bizarre helium voice, knew that he was telegenic before the term had even been invented. He cleverly utilised television, including through a Disney family programme called Man and the Moon; reputation veneering was one of his greatest achievements. But in focusing on the WVB story the film also undermines its own footing. The early voiceover promises newly declassified documents and exclusive footage, but by part four it's not clear what here is new. Only those who know nothing of von Braun – how he used to be perceived; how history judges him now – will be surprised at the documentary's conclusion. (That von Braun was allowed to outrun his Nazi past because of his scientific achievements.) And that takes some doing: von Braun crops up time and time again in popular culture, from Apple TV's space race drama For All Mankind to the Sixties satirist Tom Lehrer's song Wernher von Braun ('A man whose allegiance / Is ruled by expedience'). At the same time, here we have author Wayne Biddle on camera reminding us that his book Dark Side of the Moon, which came out in 2009, told us all of this 15 years ago. 'If he [von Braun] survives as a hero it's out of ignorance,' says a slightly tired-of-all-this Biddle. The question, then, is that if the von Braun story is old news, what in Nasa, Nazis and the Space Race is new? The answer is not much. Like re-reading a newspaper, it's an enjoyable, accomplished, but never revelatory way to pass the time.
