Tourists normally have to pay big money and brave cold climates for a chance to see an aurora, but last weekend many people around the world simply had to look up to see these colorful displays dance across the sky.
Usually banished to the poles of Earth, the auroras strayed as far as Mexico, southern Europe and South Africa on the evening of May 10, delighting skygazers and filling social media with images of exuberant pinks, greens and purples.
But for those charged with protecting Earth from powerful solar storms such as the one that caused the auroras, a threat lurks beneath the stunning colors.
"We need to understand that behind this beauty, there is danger," Quentin Verspieren, the European Space Agency's space safety program coordinator, told AFP.
Mike Bettwy of the US Space Weather Prediction Center said that "we're focused on the more sinister potential impacts" of solar storms, such as taking out power grids and satellites, or exposing astronauts to dangerous levels of radiation.
The latest auroras were caused by the most powerful geomagnetic storm since the "Halloween Storms" of October 2003, which sparked blackouts in Sweden and damaged power infrastructure in South Africa.

There appears to have been less damage from the latest solar storms, though it often takes weeks for satellite companies to reveal problems, Bettwy said.
There were reports that some self-driving farm tractors in the United States stopped in their tracks when their GPS guidance systems went out due to the storm, he told AFP.
'Definitely not over'
These strange effects are caused by massive explosions on the surface of the Sun that shoot out plasma, radiation and even magnetic fields at incredibly fast speeds born on the solar wind.
The recent activity has come from a sunspot cluster 17 times the size of Earth which has continued raging over the week. On Tuesday it blasted out the strongest solar flare seen in years.
The sunspot has been turning towards the edge of the Sun's disc, so activity is expected to die down in the short term as its outbursts aim away from our planet.
But in roughly two weeks the sunspot will swing back around, again turning its gaze towards Earth.
In the meantime, another sunspot is "coming into view right now" which could trigger "major activity in the coming days", ESA space weather service coordinator Alexi Glover told AFP.
So the solar activity is "definitely not over", she added.
It is difficult to predict how violent these sunspots could be -- or whether they could spark further auroras.
But solar activity is only just approaching the peak of its roughly 11-year cycle, so the odds of another major storm are highest "between now and the end of next year", Bettwy said.
What threat do solar storms pose?
Geomagnetic storms such as the recent one create a magnetic charge of voltage and current, "essentially overloading" things like satellites and power grids, according to Bettwy.
The most famous example came in 1859 during the worst solar storm in recorded history, called the Carrington Event.
As well as stunning auroras, the storm caused sparks to fly off of telegraph stations. The charge that originated from the Sun was so strong that some telegraphs worked without being plugged into a power source.
So what would happen if such a powerful geomagnetic storm struck Earth again?
Bettwy said most countries have improved their power grids, which should prevent prolonged outages like those that hit Sweden in 2003 or Canada in 1989.
Still, he suggested people have an emergency kit in case electricity is knocked out for a day or two. Fresh water might also help in case filtration plants go offline.
Astronauts are particularly at risk from radiation during extreme solar activity. Those on the International Space Station usually take the best shelter they can when a bad storm is expected.
Bettwy said a massive solar storm could expose astronauts to an "unhealthy dose" of radiation, but he did not think it would be lethal.
Emphasizing that he did not want to "instill fear", Bettwy added that radiation can also potentially "get through the fuselage" of planes flying near the north pole.
Airlines sometimes change routes during extreme solar storms to avoid this happening, he added.
Several upcoming missions are expected to improve forecasting of the Sun's intense and unpredictable weather, aiming to give Earth more time to prepare.

Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

German scientists claim to have “rejuvenated” human eggs for the first time in an advance that they predict could revolutionize IVF success rates for older women.

The groundbreaking research suggests that an age-related defect that causes genetic errors in embryos could be reversed by supplementing eggs with a crucial protein, according to The Guardian.

When eggs donated by fertility patients were given microinjections of the protein, they were almost half as likely to show the defect compared with untreated eggs.

If confirmed in more extensive trials, the approach has the potential to improve egg quality, which is the primary cause of IVF failure and miscarriage in older women.

The decline in egg quality is the main reason IVF success rates drop steeply with female age and is why the risk of chromosome disorders such as Down’s syndrome increases with maternal age.

“Overall we can nearly halve the number of eggs with [abnormal] chromosomes. That’s a very prominent improvement,” said Prof Melina Schuh, a director at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and a co-founder of Ovo Labs, which is aiming to commercialize the technique.

“Most women in their early 40s do have eggs, but nearly all of the eggs have incorrect chromosome numbers,” added Schuh, whose lab has been investigating egg biology for the past two decades. “This was the motivation for wanting to address this problem.”

The latest approach targets a vulnerability in eggs linked to a process called meiosis, in which sex cells (eggs or sperm) jettison half their genetic material so they can join together to make an embryo.

In eggs, this requires 23 pairs of X-shaped chromosomes to align along a single axis in the cell. On fertilization, the cell divides causing the chromosome pairs to be – ideally – neatly snapped down their centers to create a cell with precisely 23 single chromosomes from the mother, the rest being delivered by the sperm.

However, in older eggs the chromosome pairs tend to loosen at their midpoint, becoming slightly unstuck or detaching entirely before fertilization.

In this scenario, the X-shaped structures fail to line up properly and move around chaotically in the cell, so when the cell divides they are not snapped symmetrically.

This results in an embryo with too many or too few chromosomes.

Schuh and colleagues previously found that a protein, Shugoshin 1, which appears to act as a glue for the chromosome pairs, declines with age. In the latest experiments in mouse and human eggs, they found that microinjections of Shugoshin 1 appeared to reverse the problem of chromosome pairs separating prematurely.

Using eggs donated by patients at the Bourn Hall fertility clinic in Cambridge, they found that the number showing the defect decreased from 53% in control eggs to 29% in treated eggs. When they looked only at eggs from women over 35 years of age, a similar trend was seen (65% compared with 44%), although this result was not statistically significant, which the scientists said was probably due to them only having treated nine eggs in this age range.

Dr Agata Zielinska, a co-founder and co-CEO of Ovo Labs, said: “Currently, when it comes to female factor infertility, the only solution that’s available to most patients is trying IVF multiple times so that, cumulatively, your likelihood of success increases. What we envision is that many more women would be able to conceive within a single IVF cycle.”

The findings will be presented at the British Fertility Conference in Edinburgh on Friday and have been published as a preprint paper on the Biorxiv website.

Swiss author Erich von Daeniken, who helped popularize the idea that astronauts from outer space visited Earth ​to help lay the foundations for human civilization, has died aged 90.

Swiss media including national broadcaster SRF reported his death, and a note on his website said it occurred on Saturday, The AP news reported.

Von Daeniken rose to ‌prominence with ‌his 1968 book "Chariots of ‌the ⁠Gods?" ​which posited ‌that structures such as the pyramids of Ancient Egypt, Britain's Stonehenge and Peru's Nazca lines were too advanced for their time, and needed outside help.

"In my opinion, ancient structures were made ⁠by humans, not by the extraterrestrials, but it was ‌the extraterrestrials who guided them, ‍who them, ‍who gave them the knowledge how to ‍do it," von Daeniken says in a video on his YouTube channel.

His theories were controversial with historians, scientists and fellow ​writers. But they were popular, and his books, which included "The Gods were ⁠Astronauts", sold nearly 70 million copies worldwide, appearing in more than 30 languages, SRF said.

Von Daeniken argued that ancient religions, myths and art contained evidence that millennia ago, the ancestors of modern humans had made contact with advanced extraterrestrial beings who appeared godlike to them and enabled them to progress.

One ‌day, von Daeniken said, those beings would return.

One of the largest and oldest icebergs ever tracked by scientists has turned blue and is “on the verge of complete disintegration,” NASA said on Thursday.

A23a, a massive wall of ice that was once twice the size of Rhode Island, is drenched in blue meltwater as it drifts in the South Atlantic off the eastern tip of South America, NASA said in a new release, according to CBS News.

A NASA satellite captured an image of the fading berg the day after Christmas, showing pools of blue meltwater on its surface. A day later, an astronaut aboard the International Space Station captured a photograph showing a closer view of the iceberg, with an even larger melt pool.

The satellite image suggests that the A23a has also “sprung a leak,” NASA said, as the weight of the water pooling at the top of the berg punched through the ice.

Scientists say all signs indicate the so-called “megaberg” could be just days or weeks from totally disintegrating as it rides currents that are pushing it toward even warmer waters.

Warmer air temperatures during this season could also speed up A23a's demise in an area that ice experts have dubbed a “graveyard” for icebergs.

“I certainly don't expect A-23A to last through the austral summer,” retired University of Maryland, Baltimore County scientist Chris Shuman said in a statement.

Blue and white linear patterns visible on A23a are likely related to striations, which are ridges that were scoured hundreds of years ago when the iceberg was part of the Antarctic bedrock, NASA said.

“The striations formed parallel to the direction of flow, which ultimately created subtle ridges and valleys on the top of the iceberg that now direct the flow of meltwater,” said Walt Meier, a senior research scientist at the National Snow & Ice Data Center.

The berg detached from Antarctica in 1986. It remained stuck for over 30 years before finally breaking free in 2020.

According to current estimates from the US National Ice Center, in early January 2026, the berg's area is 1,182 square kilometers -- still larger than New York City but a fraction of its initial size.
