Have scientists just found a new cosmic source of gold? How 'starquakes' might forge the glittering metal
For decades, astronomers have puzzled over one of the universe's most glittering mysteries: where does gold come from? While the origins of elements like hydrogen and helium trace back to the Big Bang, and heavier elements like iron are born in the explosive deaths of stars, gold—being far heavier—has long been an enigma. Until now, the only known factories of this precious metal were the spectacular collisions of
neutron stars
, the ultra-dense remnants of supernovae.

But according to a report from
CNN
, a new study has cracked open a cosmic cold case with a dramatic revelation: gold might also be born from the flares of magnetars—supercharged neutron stars with magnetic fields a quadrillion times stronger than Earth's. If true, the implications don't just shake up our understanding of cosmic chemistry—they rewrite it.
When Stars Quake Like Earth
The potential breakthrough comes from a deeper look at data collected nearly 20 years ago. Researchers analyzing signals from NASA and ESA space telescopes discovered a
gamma-ray burst
from 2004 that aligns remarkably well with theoretical models of a magnetar explosion. These models suggest that under extreme conditions, when a magnetar undergoes a 'starquake'—akin to an earthquake but on a star's crust—it can eject crust material at unimaginable speeds. This material, they argue, could contain the seeds of gold and other
heavy elements

'We think the starquakes on
magnetars
produce short, intense bursts of X-rays,' said Eric Burns, a coauthor of the study and astrophysicist at Louisiana State University. 'Sometimes, one of these flares becomes so massive, it hurls part of the star's surface into space.' And that, scientists now believe, might just be enough to spark the creation of gold.

Cosmic Archaeology in Gamma Rays
The 2004 event, captured by the INTEGRAL mission and long forgotten, suddenly re-emerged as a golden lead. Matching this ancient gamma-ray signature with predictions from Columbia University's Brian Metzger and his team, the researchers found eerie similarities—evidence that the flare may have, in fact, carried the fingerprint of heavy element production.
Lead author Anirudh Patel, a PhD student at Columbia, likened the discovery to a surprise holiday gift. 'When we built our models in December 2024, we didn't realize the signal had already been hiding in plain sight,' he said. 'It's incredible to think that gold used in everyday electronics could have been forged in such a violent, ancient blast.'
Not Everyone's Convinced—Yet
While the excitement is palpable, not all astrophysicists are ready to hail magnetars as gold mines. Dr. Eleonora Troja, who helped confirm the gold-making potential of neutron star collisions in 2017, urged caution. 'Magnetars are chaotic, messy systems,' she said. 'They may add too many electrons, which could lead to lighter metals like silver or zirconium, rather than gold.'
She agrees that the flare presents a fascinating possibility but warns it's not yet definitive proof. The creation of gold, she noted, requires a very specific recipe—and magnetars might not always have the right ingredients.

To truly determine if magnetars are responsible for scattering stardust treasures across the galaxy, scientists will need more than archival data. That's where NASA's upcoming Compton Spectrometer and Imager (COSI), set to launch in 2027, comes in. Designed to detect gamma rays from cosmic phenomena, COSI could track future magnetar flares in real time and search for the chemical fingerprints of heavy elements.
Until then, the mystery remains tantalizing. Are these fiery, magnetic titans quietly churning out gold as they quake and flare across the universe? Or is this just one of many illusions in the great cosmic forge?
Whatever the answer, one thing is clear: our search for celestial gold is far from over—and the universe may be hiding its treasure in the most explosive places.

Experts Dismiss Viral Report Claiming Hidden City Beneath Egypt's Pyramids
Last Updated: In ground-breaking research, a group of scientists earlier claimed to have discovered evidence of a second underground city beneath Egypt's Giza Plateau. The history of the Pyramids, located in Egypt, still remains a mystery, notably for their construction. While the ancient Egyptians were in charge of building them, the exact methods, tools, and resources employed are still being researched and debated today. In a ground-breaking research, a group of scientists earlier claimed to have discovered evidence of a second underground city beneath Egypt's Giza Plateau, connecting the Khafre Pyramid to other surrounding sites. But now, top archaeologists have refuted the previous claims, calling it 'unscientific.' As per a Daily Mail report, experts used Synthetic Aperture Radar (SAR) tomography to discover what they believe to be a huge subterranean complex connecting the Khafre, Khufu, and Menkaure pyramids, as well as the Great Sphinx. Filippo Biondi, a radar expert at the University of Strathclyde, stated that these buildings are '90 per cent likely" to be connected. 'We firmly believe that the Giza structures are interconnected, reinforcing our view that the pyramids are merely the tip of the iceberg of a colossal underground infrastructural complex," Biondi earlier told CNN. Also, the previous report claimed that the researchers had identified vertical shafts that went as far as 2,000 feet below the Khafre pyramid. According to them, the shafts could date back to a civilisation 38,000 years ago, considerably older than the pyramids, which were built around 4,500 years ago. Egypt's pyramids are ancient masonry buildings designed primarily as tombs for pharaohs and their consorts during the Old and Middle Kingdom periods. Over 130 pyramids have been discovered in Egypt, with many of them part of larger complexes. The Great Pyramid of Giza, built for Pharaoh Khufu, is the largest and most famous and was once the tallest man-made structure in the world. First Published:

Trump vs Musk: How a political feud threatens to send NASA into the ‘biggest crisis' in its history
$22 billion at stake Live Events NASA caught in political crossfire Human spaceflight, too, is on edge Artemis and Mars ambitions in jeopardy The SLS vs Starship debate Global partnerships fray Earth loses out DAVINCI+ and VERITAS (Venus missions) Landsat Next, critical for climate change monitoring EnVision, a joint mission with ESA Mars Sample Return, a flagship programme in partnership with ESA Existing missions like Juno, Mars Odyssey, New Horizons, and MAVEN, which could face premature shutdowns A legacy at risk (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The spectacle of President Donald Trump 's public feud with billionaire entrepreneur Elon Musk has now spilled into one of America's most strategic and fragile domains: space. What began as a war of words over a contentious spending bill has become a flashpoint threatening to unravel decades of US leadership in space science and the centre of the dispute is the White House's proposed federal budget, which seeks to radically reshape NASA's priorities. If passed, it could place over 40 current and future missions at risk, many involving climate science and planetary exploration, while funnelling resources into a narrowly defined vision: putting American boots back on the Moon, and eventually, on fuel to the fire, Trump has openly threatened to cancel federal contracts with Musk's SpaceX, a company now central to NASA's operations. That threat risks not only logistical disruptions, like resupplying the International Space Station ISS ), but also casts long shadows over future crewed missions that depend on SpaceX's Starship rocket.'The astonishing exchanges, snap decisions and U-turns we've witnessed in the last week undermine the very foundations that we build our ambitions on,' said Dr Simeon Barber, space scientist at the Open University, as quoted by the BBC. 'Space science and exploration rely upon long-term planning and cooperation between government, companies and academic institutions.'At the heart of the storm are nearly $22 billion in government contracts awarded to SpaceX, spanning NASA's Commercial Crew Program, ISS cargo missions, and the Artemis Moon programme. The feud escalated on June 5, 2025, when Trump publicly threatened to scrap all government contracts with Musk's responded with a dramatic (later-deleted) post on X:'In light of the President's statement about cancellation of my government contracts, @SpaceX will begin decommissioning its Dragon spacecraft immediately.'He later backed down, replying to a user urging restraint:'Good advice. Ok, we won't decommission Dragon.'Even before this drama unfolded, NASA was staring down an existential challenge. The proposed budget includes a 25% overall cut, with science and Earth observation missions absorbing the brunt. Programmes that track climate change, explore the solar system, and enable global partnerships, some decades in the making, are now Dreier, chief of space policy at the Planetary Society, called it 'the biggest crisis ever to face the US space programme.' That's no exaggeration: while the budget proposes a $100 million boost for Mars-related initiatives, almost everything else is on the chopping block.'President Trump is repurposing NASA to land astronauts on the Moon before the Chinese, and eventually to plant a US flag on Mars,' said Dr Adam Baker, a space analyst at Cranfield University, reported BBC. 'Everything else is secondary.'SpaceX's Crew Dragon is currently NASA's only certified spacecraft capable of carrying astronauts to and from the ISS. Under a $5 billion contract, it ended NASA's reliance on Russia's Soyuz after the Space Shuttle's Crew Dragon is supporting the Crew-10 mission, while Axiom Space prepares a fourth private astronaut mission. Boeing's Starliner remains uncertified and unproven for long-term operational SpaceX, human spaceflight missions could face serious setbacks, Dreier warned:'The potential cancellation of these contracts would delay or completely halt US-led missions to the ISS.'NASA's Artemis III mission, aiming to land astronauts on the Moon in 2027, relies on SpaceX's Starship as its lunar lander. So far, the company has received over $15 billion in NASA contracts for Falcon 9 and Starship Starship's recent test flights have ended in failure, and if the partnership collapses, it could derail timelines and leave the door open for rivals, particularly China, to lead in lunar long-touted goal of sending astronauts to Mars, once aligned with Musk's vision, now appears politically volatile. This focus comes at the cost of near-term science and Earth-based officials have justified the cuts as a streamlining effort. NASA's Space Launch System (SLS), with a staggering $4.1 billion launch cost, has long been criticised for overruns and delays. The budget proposes sidelining SLS in favour of cheaper, reusable the private sector may not offer the stability required. Starship's repeated failures and Blue Origin's early-stage development raise questions.'The worry is that NASA may be jumping out of the frying pan into the fire,' Dr Barber said. 'If SpaceX or Blue Origin run into trouble, Congress will have to foot the bill anyway.'NASA is not just a national agency; it's a cornerstone of international space cooperation. Two major joint missions with the European Space Agency, Mars Sample Return and the Rosalind Franklin rover, are in jeopardy due to US budget cuts.'These missions are more than science, they're signals of trust and cooperation,' said Prof Sir Martin Sweeting of Surrey Satellite Technology has signalled plans to build more autonomous space capabilities, reflecting a future where it cannot depend on US some of the worst-hit programmes are the ones that help protect our own planet. Earth observation satellites, critical for tracking wildfires, droughts, and sea level rise, are at risk of 40 active or planned missions are now in danger, including:As per NASA's muted official response came via spokesperson Bethany Stevens:'NASA will continue to execute upon the President's vision for the future of space. We will continue to work with our industry partners to ensure the President's objectives in space are met.'But former Deputy Administrator Lori Garver was more direct:'A rogue CEO threatening to decommission spacecraft, putting astronauts' lives at risk, is untenable.'This isn't just about rockets or rivalries. It's about a legacy of American leadership in space that now faces erosion due to political volatility and personal per Reuters, if Congress approves the budget, or allows it to take effect by default, the damage could be irreversible. NASA's 18,000-strong workforce faces uncertainty, and global trust in US-led space efforts may erode for years to Dreier puts it: 'Once space missions are turned off, it is hard, if not impossible, to start them up again.'

Shubhanshu Shukla expected to carry aamras, halwa to space as part of Axiom Mission 4; sister refutes claim dishes are homemade: ‘It is just impossible'
The Axiom-4 mission, which was scheduled to carry Indian astronaut Shubhanshu Shukla and three others to the International Space Station on Tuesday, was postponed again to fix a leak in SpaceX's Falcon-9 rocket, Indian Space Research Organisation (ISRO) chairman V. Narayanan said in a statement. Shukla is the second Indian to travel to space after Rakesh Sharma, who completed an eight-day orbit of Earth in 1984. As the Indian Air Force pilot awaits his turn, here are some edible things he is set to carry to space. He is carrying moong dal halwa, gajar ka halwa, and aamras. As I prepare to spend 14 days abroad the ISS, I carry with me not just instruments and equipment but the hopes and dreams of a billion hearts, Shubhanshu said in a video titled 'Crew Countdown to Launch ' on Axiom Space's YouTube channel. Responding to a user's question about his food aboard the spacecraft, he said, 'I am carrying a few delicacies from India. You know, we have a rich culinary heritage. A few items I am carrying are aamras (mango nectar), moong dal halwa, and carrot halwa. Some of them are my favourites, and I am so happy to be able to carry them and share them with my colleagues and the astronauts at the station right now.' While multiple reports mention that the delicacies have been prepared by his family in Lucknow, his sister Suchi Shukla firmly refuted the claims. 'We also learned from the Axiom interview that he is set to carry these foods to space. Families are never allowed to interfere in such missions. It is untrue that he carries any of these foods from home. It is just impossible because they have their protocol and guidelines to follow,' Suchi told in an exclusive interaction. Suchi added that as a yoga practitioner and a health enthusiast, Shubhanshu eats healthy food with minimal oil. 'While he was always a foodie, he cut down on food once he joined the National Defence Academy. His meals are structured according to his rigorous training,' Suchi continued. 'When at home, he prefers to eat only home-cooked, simple food like dal chawal with less oil.' She also spoke about the mission's delay, adding that the family is also waiting for an update on the spaceflight's departure. 'We have Nothing to say. We are as clueless. Let's wait for an update soon,' said Suchi. Interestingly, according to ISRO, the idea is also to study the impact of spaceflight on the germination and growth of crop seeds. Through the Sprouting Salad Seeds in Space experiment, a joint effort by ISRO, NASA, and BioServe, sprouted seeds will be studied for their genetics, microbial load, and nutritional profile after the mission. 'This project aims to help understand how crops may be grown in space for future exploration missions,' Axiom-4 stated on its website. We consulted an expert to understand how the concept of eating and food preservation in space differs from that on Earth. Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital, Delhi, said that food in space is a fascinating topic, especially when astronauts get to enjoy traditional Indian delicacies like gajar ka halwa and aamras while orbiting the Earth. 'But eating in space is not as simple as on Earth. It involves meticulous planning, preservation, and specially designed tools to ensure nutrition and safety in a microgravity environment,' said Dr Singla. Freeze-drying is carried out to maintain food quality and extend shelf life in space. It removes water from food, making it lightweight and compact, while preserving its nutritional value. 'These foods are rehydrated with water before consumption. Thermostabilisation involves heating food to eliminate bacteria and prolong shelf life; such items are typically packaged in cans or pouches and can be stored at room temperature,' said Dr Singla. Dr Singla noted that irradiation is another technique, using ionizing radiation to sterilise certain foods like beef steak and smoked turkey. 'Rehydratable foods, like instant noodles, soups, and cereals, are also common; water is added just before consumption,' said Dr Singla. Eating in a microgravity environment requires special considerations. Dr Singla said that food is packaged in specially designed containers that prevent liquids and crumbs from floating away, which could pose a risk to equipment and astronauts. 'Rehydration is done using a water gun to inject water into freeze-dried food packets, which are then opened with scissors. Meals are typically placed on food trays that can be strapped to the astronaut's leg or a surface to keep them from floating away. Utensils like spoons, forks, and knives are equipped with magnets so they stay attached to the tray when not in use,' said Dr Singla. Since microgravity presents unique challenges, floating food particles and liquids must be controlled, epxerts urge. 'Storage is limited on spacecraft, so food must be carefully chosen and compactly packaged to reduce waste,' said Dr Singla. Above all, maintaining a balanced diet is crucial. 'Astronauts need optimal nutrition to stay healthy and perform well during missions, making meal planning a critical aspect of space travel,' said Dr Singla.
