The Sun Is 'Glitching.' Scientists Investigated and Solved a Cosmic Mystery

Scientists have peered inside the Sun and observed subtle shifts and “glitches” that have occurred over four decades, shedding light on the enigmatic long-term vibrations of our star, reports a study published on Tuesday in Monthly Notices of the Royal Astronomical Society.

The Sun goes through a roughly 11-year cycle that includes a period of high and low activity, known as solar maximum and minimum. The past few cycles have revealed changes in solar behavior that could have implications for predicting space weather and unraveling the internal dynamics of our Sun, along with other Sun-like stars.

To drill down on this mystery, researchers with the Birmingham Solar-Oscillations Network (BiSON), a network of telescopes that have monitored the Sun since the 1970s, compared the last four solar minima using this unique 40-year dataset and focused on internal vibrations that make the sun subtly oscillate.

“The entire Sun oscillates in a globally coherent way, and the oscillations are formed by sound waves trapped inside the Sun that make it resonate just like a musical instrument,”said Bill Chaplin, a professor of astrophysics at the University of Birmingham who co-authored the study, in a call with 404 Media.

“For this particular study, we were interested in seeing whether there are differences in what the Sun is doing in its structure when you focus on the periods or epochs when the Sun is very quiet,” he continued. “The last few cycles have seen some quite marked changes in behavior.”

For example, scientists have been perplexed for years by an unusually long and quiet solar minimum between cycle 23 to 24, which occurred from 2008 to 2009. Chaplin and his colleagues were able to use BiSON’s long record of asteroseismology—the study of stellar interiors—to directly contrast the interior vibrations of the Sun during this minimum to others.

“There were hints that there were things that were different” about this cycle, said Chaplin. “But now that we have the cycle 24-25 minimum—the last one in about 2019—in the bag, then we thought, ‘okay, now's the time to actually go back and look at this.’”

The team specifically looked for an acoustic wave “glitch” caused by an interior layer in which helium atoms lose electrons, producing a detectable change in the Sun’s internal structure. This glitch was significantly stronger during the 2008–2009 minimum, suggesting that the Sun’s outer interior was slightly hotter and allowed sound waves to travel faster at that time of magnetic weakness.

“The ionizing helium affects the speed at which the sound waves move through that region,” explained Chaplin. “It leaves a characteristic imprint.”

“It's not just that there is a difference with the other cycles, but it's starting to tell us about what physically has really changed beneath the surface,” he added. “They're quite subtle changes, but it's nevertheless giving us clues as to what is actually happening beneath the Sun during this very quiet period.”

The results confirm that the Sun doesn’t return to the same minimum baseline at the end of every cycle, and its activity varies within timescales of decades and centuries. For example, Chaplin pointed to one bizarrely long quiet period from 1645 to 1715, known as the Maunder Minimum.

Astronomers during this time marvelled at the prolonged lack of visible sunspots on the Sun’s surface, a sign of extremely low solar activity. Centuries later, BiSON and other solar observatories are allowing scientists to study the interior dynamics behind these shifts in depth for the first time.

“This is the first step in actually demonstrating that there are changes,” Chaplin said. “Does this mean that there are systematic changes in the way that the Sun is generating its field? It's really only now, because we have this long dataset, that we can start to ask questions like that. Previously, we just didn't have enough data to say.”

Scientists hope to keep recording the long-term behavior of the Sun with projects like BiSON so that we can better understand its mercurial nature over time. This is interesting work on its own merits, but it is also useful for refining forecasts of space storms that can wreak havoc on power grids and space assets (while also producing pretty auroras).

Chaplin also nodded to the European space telescope PLAnetary Transits and Oscillations of stars (PLATO), due for launch in 2027. This mission will search for analogous oscillations in stars beyond the Sun, building on similar work conducted by NASA’s retired Kepler space telescope.

Studying the vibrations of the Sun and other similar stars is not only important for life here on Earth; it also has implications in the search for extraterrestrial life, because local solar activity is one key to assessing the habitability of star systems similar to our own.

“The data that we have on other stars from Kepler has really helped to understand and get a better picture of the cyclic variability of other stars, like the Sun,” Chaplin concluded. “But it's still not an entirely clear picture; let's put it that way. Seismology now enables you to do really detailed analysis of stars that you can't do by other means.”

The FBI Discusses the Potential to Use AI to Hack Targets

Update: after this article was published, the national press office for the FBI said in a statement that “Hemmen was discussing hypothetical FBI application of AI technology in the context of positive and negative outcomes resulting from the technology's development.” For clarity, 404 Media has updated the headline, included the FBI’s full statement below, but left the original article intact so readers can see the comments made at the conference. An FBI spokesperson told 404 Media that “DAD Hemmen was discussing hypothetical FBI application of AI technology in the context of positive and negative outcomes resulting from the technology's development. FBI's current deployment of AI is inventoried, reviewed, and reported per Executive Order requirements, OMB guidance, and guidance from other relevant authorities. All FBI operations are conducted in accordance with the Constitution, applicable statutes, executive orders, Department of Justice regulations and policies, and Attorney General guidelines.”

The FBI is using artificial intelligence in what it describes as “remote access operations,” FBI parlance for hacking, according to an FBI official.

The comments, given at a national security and AI conference 404 Media was attending, give an unusually candid admission of the FBI’s use of hacking tools, which are often shrouded in secrecy.

X Will Stop Paying People for Sharing Unlabeled AI-Generated War Footage

X said it will temporarily demonetize accounts that share AI-generated war footage without a label. The decision comes days after the US and Israel launched airstrikes in Iran and AI-slop war footage flooded social media timelines across the internet.

“Today we are revising our Creator Revenue Sharing policies to maintain authenticity of content on Timeline and prevent manipulation of the program. During times of war, it is critical that people have access to authentic information on the ground. With today’s AI technologies, it is trivial to create content that can mislead people,” Nikita Bier, X’s head of product, said in a post on X.

Many of the AI-generated videos currently on X purport to show Iranian ballistic missiles hitting sites in Israel. One video shared thousands of times on X showed missiles slamming into the ground near the Dome of the Rock in Jerusalem while a computer generated voice said “Oh my god, hear they come.” X users community noted the video, but the account that shared it has a Bluecheck and is eligible for a financial payout for engagement as part of X’s content creator program.

Up to now, the Iranians have been deliberately firing their older missiles and drones, using them as expendable bait to drain US and Israeli air defenses.
That strategy clearly worked.

Now they’re escalating, rolling out their more advanced ballistic missiles and drones.

Bier said today that X will stop people from making money on unlabeled AI war footage, but won’t stop accounts from sharing it.

“Starting now, users who post AI-generated videos of an armed conflict—without adding a disclosure that it was made with AI—will be suspended from Creator Revenue Sharing for 90 days. Subsequent violations will result in a permanent suspension from the program,” he added. “This will be flagged to us by any post with a Community Note or if the content contains meta data (or other signals) from generative AI tools. We will continue to refine our policies and product to ensure X can be trusted during these critical moments.”

Fake war footage shared on social media isn’t a new problem. For several years every new conflict would be met with a flood of fake videos. Old war footage passed off as coming from the current war was popular, but so was recordings of video games run through filters to make it look low-resolution. The same three clips from milsim video game Arma 3 were shared at the outbreak of every new conflict for a decade. The Government of Pakistan even shared Arma 3 footage once in a post that’s still live on X.

What is new is the proliferation of easy to use AI video-generation tools. AI image and video generation has come a long way in the past few years and it’s trivially easy to remove the watermark that’s supposed to distinguish them from the real thing. X’s verification system—which rewards accounts for engagement—has also created incentives for Bluecheck accounts to publish fast, verify later (if ever), and rake in the cash. So in the hours and days after the war with Iran began, fake footage of airstrikes and conflict spread on X.

The way X is handling the problem gives the game away. According to Bier, the site will rely on the community to police itself and the punishment is a 90 day suspension not from the site but from the monetization program.

New Podcast Alert: The Globe-Spanning, Multi-Newsroom Hunt for Mr. Deepfakes

Mr. Deepfakes was the biggest website in the world for sharing AI-generated abuse imagery, swapping tips and tricks for more realistic results, and posting endless, fake, nonconsensual videos of everyone from celebrities to everyday people. In a new podcast by the CBC, I got to tell the tale of how deepfakes started, what targets go through, and where we go next.

It's called Understood: Deepfake Porn Empire. It's about the decades-long rise of non-consensual deepfake porn, the targets who are fighting back, and what it takes to stop its proliferation. Check it out here and listen wherever you get your podcasts.

The first three episodes are already up, so you can binge them all before the finale next Tuesday.

In the first episode, "The Dawn of Fake Porn," you’ll get a fascinating history of the decades of cultural and technological standards that set the stage for AI-generated nonconsensual imagery as we know it today. I learned a lot in this episode myself, including about a guy who went by “Lux Lucre” who ran two Usenet groups dedicated to fake nudes of celebrities in the 90s. This stuff goes so much farther back than you might realize.

In episode two, “So You’ve Been Deepfaked,” I got the chance to talk to Taylor, who discovered she’d been targeted by AI images while at university, working in a male-dominated field. Instead of hoping it’d go away, she set out to find her harasser, and found his other targets in the process. It all led back to one place: the biggest deepfake site in the world, Mr. Deepfakes.

Episode three just came out today: “The Notorious D.P.F.K.S.” is a romp through the investigative highs and lows that led a team of journalists scattered around the world to the door of Mr. Deepfakes himself. I was so thrilled to talk to investigative journalist Ida Herskind, OSINT specialist Zakaria Hameed, and Bellingcat’s Ross Higgins in this episode. Come for the How I Met Your Mother references, stay for the gripping chase.

Episode four, the series finale, launches next week. It’s a true crime story with CBC reporters on stakeouts and infiltrating hospitals, and legal and social experts breaking down what it all means now that we’re in a post-Mr. Deepfakes world—but far from a post-AI abuse landscape. Follow the Understood feed wherever you listen to get it when it comes out on Tuesday.
