    Dhaka eyes end to mystery of last Nawab’s treasure trove – Newspaper

    KHAWAJA Naim Murad, the great-grandson of the last Nawab of Dhaka, speaks during an interview at his house in the Bangladesh capital.—AFP

    DHAKA: For more than a century, the fate of the dazzling Darya-i-Noor (River of Light) diamond has been sealed inside a bank vault — a mystery that haunts Khawaja Naim Murad, great-grandson of the last Nawab of Dhaka.

    Locked away in 1908, were the family’s heirlooms lost during the violence at the end of British rule in 1947? Did they survive the 1971 break-up of Pakistan and the string of coups that followed in Bangladesh, or are they still safe, dusty but untouched?

    Many suspect the jewels are long gone, and officials at a state-run bank in Dhaka hesitate to simply open the vault, fearing they’d carry the cost if it is empty.

    But the cash-strapped Bangladesh government has now ordered a committee to unseal the vault — and Murad clings to hope.

    “This is not a fairytale,” said Murad, 55, recounting a story passed down from his father about the giant diamond, the centrepiece rock of glittering armband.

    “The diamond was rectangular in shape and surrounded by more than half a dozen smaller diamonds,” Murad recalled.

    It was part of a trove of 108 treasures. According to original court documents, they include a gold-and-silver sword encrusted with diamonds, a bejewelled fez with cascading pearls, and a fabulous star brooch once owned by a French empress.

    History and myth

    The nawab’s riverside pink palace of Ahsan Manzil is now a museum.

    Murad, a former popular film star, lives in a sprawling villa in a wealthy Dhaka suburb.

    He flourished a sheaf of documents, including a family book with detailed paintings of the treasures.

    “It is one of the most famous diamonds in the world. Its history is closely associated with that of the Koh-i-Noor,” the book reports, referring to the shining centrepiece of Britain’s crown jewels — a gem also claimed by Pakistan, India, Afghanistan and Iran.

    “It is absolutely perfect in lustre.”

    Another diamond of the same name, the pink-hued Daria-i-Noor, is in Tehran as part of Iran’s former royal jewels.

    Murad maintains that the family’s diamond, too, was once owned by Persia’s shahs, then worn by Sikh warrior-leader Ranjit Singh in 19th-century Punjab. It was later seized by the British and eventually acquired by his ancestors.

    But fortunes shifted. In 1908, the then-nawab faced financial trouble.

    Sir Salimullah Bahadur borrowed from British colonial powers by mortgaging his vast Dhaka estates and placing the treasures in a vault as collateral.

    That was their last confirmed sighting. Since then, myth and history merge.

    Murad believes his uncle saw the jewels in the bank in the 1980s, but bank officials say they do not know if the vault has ever been opened.

    Salahuddin Nagri, who chairs Bangl­a­d­e­sh’s Land Reforms Board, , says the government body inherited custody of the trove, held in a state-owned bank.

    “But I haven’t seen any of the jewels yet,” he said.

    Vault is sealed

    The 1908 court papers did not specify the diamond’s carat weight, but valued it at 500,000 rupees — part of a hoard worth 1.8 million rupees.

    By today’s conversion, that equals roughly $13 million, though experts say the market value of such rare and large jewels has since sometimes soared many times higher.

    Today’s guardian, Shawkat Ali Khan, managing director of Sonali Bank, said the safe remains shut.

    “The vault is sealed,” Shawkat Khan said. “Many years ago an inspection team came to check on the jewels, but they never really opened it. They just opened the gate that held the vault.”

    He is keen for the vault to be opened at last, though no date yet has been given.

    “I am excited,” he said with a brief smile.

    The family hopes to discover if any of the century-old debt remains, and whether they could reclaim the jewels.

    Murad dreams of diamonds, but says his real wish is to simply see the treasure for himself.

    “We believe that if anyone dies in debt, his soul never finds peace.”

  • Situationer: Why breaching is ‘not an option’ for Sindh – Newspaper

    Situationer: Why breaching is ‘not an option’ for Sindh – Newspaper

    AS PUNJAB continues to use breaches to divert water from its overflowing rivers, Sindh may not be able to emulate this strategy due to its unique topography, with the minister concerned categorically ruling out this option.

    Over the past week, authorities in Punjab have destroyed several embankments to save major cities from being inundated. Naturally, the Sindh government has been facing queries about whether a similar strategy will be deployed in the province.

    The swollen eastern rivers of Ravi, Chenab, and Sutlej merge into the Indus River at Panjnad before entering Sindh, and the province faces a similar situation to the one it faced in September 2014.

    The Indus River has already passed a medium and high flood through the Guddu and Sukkur barrages in July and August of this season.

    Minister says Punjab’s strategy can’t be emulated downstream due to province’s peculiar topography

    How much water will pass through Guddu now remains a guessing game, considering flow patterns at the barrage. The Trimmu barrage passed a peak of 550,965 cusecs on Sept 1, but the flows have yet to reach Guddu.

    Officials remain unsure whether floodwaters from the Chenab would precede combined flows from the Ravi and Sutlej, which would accumulate at Panjnad before heading to Guddu.

    With a discharge capacity of 865,000 cusecs against Trimmu’s 875,000, Panjnad is the second last destination before the tributaries merge into the mighty Indus.

    Sindh Irrigation Minister Jam Khan Shoro, who is stationed at the Sukkur Barrage to monitor floods, told Dawn that breaches were not an option.

    “There is no option of breach in our minds,” he said, adding that Sindh’s topography tells a different story when it comes to such decisions.

    “Gradient in Sindh’s lands is lower than the Indus River,” he argued, while asking people not to worry about any possible breaches. “I tell those putting this query that we can’t breach a dyke. It’s not an option,” he assured.

    Peculiar gradient

    Explaining this phenomenon, Tando Jam Sindh Agriculture University (SAU) Vice Chancellor Prof Dr Altaf Siyal said there were variables in the soil gradient in Punjab and Sindh and breaching a dyke was a different story for each province.

    “A breach can be made on either side of the Indus. If it occurs on the right bank, the water will head westward because those pockets have large depressions. In case of a breach on the left bank, it will impact the Nara canal of Sukkur Barrage first before heading downstream,” Dr Siyal said.

    A breach around Khairpur Mirs and Naushahro Feroze would send water to the river from the Qazi Ahmed side on the left bank of the Indus.

    According to him, any breach on the right bank upstream of Sukkur will send water down to Manchhar Lake via the Right Bank Outfall Drain (RBOD)/Main Nara Valley Drain (MNVD).

    “Manchhar Lake then allows the authorities to redirect water to the Indus if the river flows remain on the lower side,” he said, alluding to the 2010 super floods.

    In 2010, a massive breach 60km downstream of Guddu displaced millions after the Tori Bund developed a fissure, affecting seven districts on the right bank. The water eventually ended up in the lake.

    In 2022, heavy rainfall in the Kirthar Range inundated parts of the right bank districts, including Qambar-Shahdadkot, Larkana, Dadu, and Jamshoro. These flows entered the Indus after Manchhar had to be breached the same month at two locations.

    A high-powered judicial commission was formed to probe the causes of the 2010 flood breaches at Tori and Molchand-Surjani at Kot Almo in Thatta, downstream of Kotri Barrage, on Aug 27, 2010.

    The report mentioned that around 1.47MAF water was released from Tori and 70pc of the 150km on Begari Sindh Feeder, an off-taking channel of Guddu Barrage on its right side was destroyed.

    The chief engineer of the Guddu barrage and his team, along with the irrigation secretary, were held responsible for negligence.

    Discharges in Punjab

    Mr Jam and Irrigation Secretary Zarif Khero also shared information about discharges recorded in Punjab, especially at Trimmu, Panjnad, Head Sidhnai over Ravi (with 157,580 cusecs discharge at 4pm Wednesday) and Sulemanki over Sutlej (122,736 cusecs). Chenab, in fact, passed a peak of 1,077,951 cusecs in the last week of August, which Sindh is now waiting for.

    “Let’s see which peak reaches Guddu first. My hunch is that the time lag between barrages has increased,” he said.

    Sutlej and Ravi are passing their peaks, too, and the water will head for Guddu while Indus water from Taunsa will also reach the first barrage in Sindh, adding to these discharges. Panjnad’s downstream flow was 217,447 cusecs at 6pm on Wednesday. These are the flows released from the Tarbela Dam built on the Indus.

    Even the National Disaster Management Authority (NDMA) mentioned that 1.3m cusecs of water would reach Guddu Barrage, which has a capacity of 1.2m cusecs.

    The irrigation secretary said that losses between the two reaches of the barrages needed to be factored in as well.

    He also drew a parallel between this year and 2014’s Chenab flows. “A discharge of 947,000 cusecs downstream Khanki [over Chenab] on Sept 7 eventually turned out to be a flow of 453,570 cusecs at Panjnad on Sept 16 and 475,000 cusecs [inclusive of Indus flows] at Guddu on Sept 19.

    He, however, assured that the government was prepared to deal with any situation involving a flow of 900,000 cusecs, considered a super flood.

  • Apple Developing AI-Powered Web Search Tool for Siri and Safari

    Apple Developing AI-Powered Web Search Tool for Siri and Safari

    Apple is reportedly developing an artificial intelligence (AI)-powered web search tool that could be added to its Siri voice assistant, its Safari web browser and its Spotlight search features on the iPhone.

    The search tool, dubbed World Knowledge Answers, would look up information from the internet and summarize the results, similar to OpenAI’s ChatGPT, Google’s AI Overviews and apps from companies like Perplexity AI, Bloomberg reported Wednesday (Sept. 3), citing unnamed sources.

    Apple did not immediately reply to PYMNTS’ request for comment.

    PYMNTS reported in November 2024 that innovation in search is getting a shot in the arm by AI-powered chat interfaces that are challenging traditional models.

    While Google has reigned supreme as the global leader in online search, a shifting technology is setting the stage for intensified competition from alternative search engines and AI-powered platforms.

    In May, while testifying in the U.S. Justice Department’s lawsuit against Google parent company Alphabet, Apple Senior Vice President of Services Eddy Cue said Apple was “actively looking at” revamping its Safari web browser to concentrate on AI-powered search engines.

    Cue noted a recent dip in Safari searches, which he attributed to increased use of AI, and said he believes that AI search engine providers such as OpenAI, Perplexity AI and Anthropic will eventually supplant standard search engines like Google.

    It was reported in July that AI-powered chatbots account for a small but growing share of searches conducted through desktop browsers.

    The share of those searches in the United States that went to chatbots rather than traditional search engines reached 5.6% in June, up from 2.48% in June 2024 and 1.3% in January 2024.

    Wednesday’s report came at a time when Apple has been facing mounting criticism that the company has lagged in the AI race.

    It was reported in August that Apple held a rare companywide meeting to cover its investment in AI and that CEO Tim Cook expressed a positive outlook about the company’s AI future, saying Apple has “exciting” plans for the technology that he wasn’t able to discuss.

    During a July earnings call, Cook said Apple is making “good progress” on integrating more AI capabilities in Siri, which are set to arrive next year.

  • Strange phenomenon happening deep in the Dead Sea

    Strange phenomenon happening deep in the Dead Sea

    (Web Desk) – Salt giants and other striking formations in the Dead Sea reveal how evaporation and fluid dynamics shape Earth’s geological past and present.

    The Dead Sea represents a unique convergence of conditions: it lies at the lowest point on Earth’s surface and contains one of the planet’s highest salt concentrations. This extreme salinity makes the water unusually dense, and its distinction as the deepest hypersaline lake produces remarkable, often temperature-driven processes beneath the surface that scientists are still working to understand.

    Among the most intriguing features are the so-called salt giants — vast accumulations of salt within the Earth’s crust.

    “These large deposits in the earth’s crust can be many, many kilometers horizontally, and they can be more than a kilometer thick in the vertical direction,” said UC Santa Barbara mechanical engineering professor Eckart Meiburg, lead author of a paper published in the Annual Review of Fluid Mechanics. “How were they generated? The Dead Sea is really the only place in the world where we can study the mechanism of these things today.”

    Although massive salt deposits are also present in places such as the Mediterranean and Red seas, the Dead Sea is the only location where they are actively forming. This makes it an unparalleled site for investigating the physical processes that govern their development, including how their thickness varies across space and time.

    “It used to be such that even in the winter when things cooled off, the top layer was still less dense than the bottom layer,” Meiburg explained. “And so as a result, there was a stratification in the salt.”

    This balance shifted in the early 1980s when partial diversion of the Jordan River reduced freshwater inflow, allowing evaporation to dominate. At that point, surface salinity reached levels comparable to the deep waters, enabling the two layers to mix. This change transformed the lake from meromictic to holomictic (a lake in which the water column overturns annually). Today, stratification still occurs, but it persists only for roughly eight months during the warmer part of the year.

  • Sources: Alyssa Thompson flies to London amid Chelsea links

    Sources: Alyssa Thompson flies to London amid Chelsea links

    Angel City FC forward Alyssa Thompson boarded a London-bound plane from Los Angeles on Wednesday as six-time reigning English champions Chelsea attempt to finalize a deal for the American, multiple sources confirmed to ESPN.

    England’s transfer deadline closes at 11 p.m. local time Thursday. Multiple sources confirmed that Angel City and Chelsea have not yet agreed to a deal, but Thompson’s departure for London signals that a transfer agreement will be reached.

    The 20-year-old Thompson missed Angel City’s league match on Monday and was listed as an excused absence. The team’s head coach Alexander Straus, who arrived on the job in June, said after Monday’s 2-1 victory over Bay FC that the prior days had been “difficult.”

    Angel City has not commented on the transfer saga as it has played out over the past week.

    Thompson has scored six goals and added two assists for Angel City this season in the NWSL. In January, Thompson signed a three-year extension with Angel City that runs through the 2028 NWSL season.

    Her 19-year-old sister, Gisele, also signed an extension through 2028 at the same time. Thompson is a Los Angeles native who skipped college — after committing to Stanford — to turn professional. Angel City selected her first overall in the 2023 NWSL Draft.

    Thompson became the first player to be drafted straight out of high school. She was the youngest player on the United States’ 2023 World Cup team later that year at 18 years old. Thompson debuted for the senior USWNT against England on Oct. 7, 2022, in front of 90,000 fans at Wembley Stadium in London.

    Chelsea is already home to United States international forward Catarina Macario and USWNT vice-captain and defender Naomi Girma. The club paid a then world record $1.1 million transfer fee to San Diego Wave FC for Girma in January.

    Chelsea have made a point to go after more USWNT talent in recent scouting efforts. A fee for Thompson, one of the NWSL’s emerging stars, is expected clear the $1 million threshold at minimum. The Orlando Pride set a new world record in August when the NWSL team paid $1.5 million to Tigres for Mexico forward Lizbeth Jacqueline Ovalle.

    ESPN’s Emily Keogh and Charlotte Gibson contributed to this report.

  • Barracuda warns of rising phishing attacks with clever URL tricks

    Barracuda warns of rising phishing attacks with clever URL tricks

    Barracuda has detected over a million phishing-as-a-service (PhaaS) attacks in the first two months of 2025, highlighting the increasing sophistication of cyber threats targeting email users worldwide.

    Researchers have reported a significant outbreak of attacks generated by the Tycoon phishing platform, which employs advanced evasion techniques to bypass traditional security measures and deceive recipients into clicking malicious links.

    New phishing techniques

    The latest Barracuda report details a range of methods used by the Tycoon platform to disguise dangerous links in phishing emails. These techniques focus on confusing automated detection systems by altering the appearance and structure of web addresses (URLs).

    Among the identified tactics is inserting a series of invisible spaces by repeatedly entering the ‘%20’ code into a URL, causing the web address to appear legitimate to both humans and machines while obscuring its true destination. Another method involves the use of obscure characters, such as a Unicode symbol resembling a dot, which can be mistaken for a standard period but functions differently in a web context.

    Tycoon-generated links may also feature hidden email addresses or special codes appended to the end of a URL, as well as the inclusion of unexpected symbols such as backslashes (”) or dollar signs (‘$’) that disrupt typical URL formats. These characters are rarely used in legitimate website addresses, making them effective for bypassing pattern-matching security tools.

    Crafted URLs

    Barracuda’s threat analysts have documented phishing attacks where URLs are structured in a way that only part of the web address is hyperlinked, with the remaining segment left as plain text. This tactic allows the dangerous section to evade detection by security solutions that analyse only clickable components.

    Attackers also manipulate URL elements by using two ‘https’ sections or omitting key markers such as ‘//’ to obscure the real destination of a link, all while ensuring the visible portion appears benign. In some cases, the ‘@’ symbol is employed, with everything preceding the symbol crafted to look reputable, such as ‘office365,’ while the actual destination, often malicious, follows after the ‘@’ sign.

    Barracuda warns that these methods are designed not only to confuse technical defences but also to deceive users who may skim over the details of an address, increasing the risk of successful phishing attempts.

    Expert commentary

    Attackers use tricks with spaces, symbols and web addresses that look trustworthy at first glance but which make it much harder for people – and traditional security software – to spot that they lead to a dangerous website.

    This warning was issued by Saravanan Mohankumar, Manager of the Threat Analysis team at Barracuda. Mohankumar further explained the ongoing evolution of cyber threats, stating, “Security tools are increasingly effective at spotting and blocking malicious links in phishing emails and this is driving attackers to continuously invent new and more sophisticated ways to disguise such links.”

    Preventative measures

    Barracuda’s current guidance recommends a “multilayered approach” to protection, combining various security measures that can identify, analyse, and block abnormal behaviours. This includes integrating artificial intelligence and machine learning at the email gateway and after email delivery, to improve detection rates for unusual or complex phishing attempts.

    The company also emphasises the importance of comprehensive security awareness training for employees, aiming to equip end-users with up-to-date knowledge and the ability to recognise and report suspicious messages. Regular training ensures a human layer of defence remains effective against threats that may bypass automated controls.

    As phishing techniques continue to develop, the report underscores the challenges facing both technology providers and users in identifying and preventing email-borne threats. Security teams are encouraged to remain vigilant for emerging tactics and adapt their defences accordingly.

  • Fifa says 2026 World Cup tickets will start at $60 but dynamic pricing looms | World Cup 2026

    Fifa says 2026 World Cup tickets will start at $60 but dynamic pricing looms | World Cup 2026

    Fifa has confirmed that it will employ dynamic pricing for tickets to the 2026 World Cup from the beginning of the sales process, which starts next week. The system was also used for this year’s Club World Cup and, in the UK, drew widespread complaints from fans buying tickets for Oasis’s comeback tour.

    The use of dynamic pricing was one of a few new details Fifa officials discussed around ticketing for the World Cup one week before sales open, including the first collection of prices. The cheapest tickets will start at $60 (£44), with the most expensive, for a prime spot at the final, starting at $6,730 (£5,760). Fifa did not provide any price points in between those two.

    Dynamic pricing means that those starting prices can, and probably will, rise significantly. This will be the first men’s World Cup to use the scheme, in which the ticket prices are adjusted by the seller to reflect demand – ­similar to the way surge pricing works for .

    Ticket companies have benefited significantly from dynamic pricing as its usage has risen over the last ­decade . Ticketmaster parent company LiveNation broke its record for revenue in 2024, with dynamic pricing thought to be a significant factor. The practice has also attracted complaints from fans priced out of events – including in high-profile cases surrounding Oasis’s tour and last season’s FA Cup final.

    Fifa officials justified the use of dynamic pricing by saying it was the organization’s way of adapting to the domestic market in the United States and Canada, where the practice is common, and where it says the public already accepts that event tickets will be priced according to demand. One official added that Fifa couldn’t pass up the additional revenue that would be generated by dynamic pricing, citing the 211 Fifa member nations that could benefit from a more profitable World Cup. According to the officials, Fifa never ran a baseline study to determine how much revenue could be generated from 2026 World Cup ticket sales without dynamic pricing – suggesting the topic was never really up for debate.

    The pricing structure is expected to be put into place immediately for the first phase of ticket sales, which begins on 10 September. Prices will fluctuate based on demand from that point on, meaning that some matches will have higher minimum price points than others before the World Cup draw has even begun.

    Fifa used dynamic pricing at the 2025 Club World Cup, with mixed results. Prices for those games initially rose sharply, only to drop – in some cases as low as $13.40 (£10) – just before kickoff as stadiums remains only partially full. However, demand at the World Cup is almost certain to be significantly higher than at the Club World Cup, and a Fifa official said that this time around prices would not go lower than $60.

    Changes to ticket categories

    Another significant change described by Fifa officials comes in the way tickets are categorized for the World Cup. In past tournaments, Fifa has broken down seats into a category system, with Category 1 generally considered to be the best seats, Category 2 the next best, and so on until Category 4. It had been standard practice for a seat’s placement in relation to the pitch to affect its categorization: a seat along the sideline, for example, was far more likely to be considered Category 1, while a seat at the same level but located behind the goal might be Category 2 or lower.

    That approach is no longer in use. In 2026, seat categories will in most cases correspond to the level of the stadium the seat is located. At the World Cup final, for example, the entire lower level of MetLife Stadium is expected to count as Category 1, with the suite level in the middle counting as Category 2, and then the upper bowl making up Categories 3 and 4.

    Once again, Fifa officials said that the change was made to bring the organization in line with perceived cultural norms in the host countries. The officials said that according to their research, North American fans place a higher emphasis on proximity to the field than they do having a certain type of view of the match.

    Where and when tickets will go on sale

    The ticket sales process for the 2026 World Cup starts on 10 September for Visa cardholders. Photograph: Fifa

    Fifa and longtime financial partner Visa announced in late July the details of the first phase of ticket sales, and those remain largely the same. From 10-19 September, Visa cardholders worldwide may submit an application on Fifa’s website, and by 29 September the randomly accepted applicants will be notified and given a date and time window in October, during which they can buy tickets. A Fifa official said that application data would be screened to prevent the influence of bots, and that the randomized draw would be made in the presence of a public notary in Zurich.

    As in past World Cups, fans may buy single-game tickets, or packages that give access to every game at a certain venue, or every game played by a specific team. Tickets will only be sold by category, with seats assigned at random within those categories until the final phase of sales, in which fans can buy specific seats on a first-come, first-served basis, many months after dynamic pricing has gone into effect.

    Fans can buy a maximum of four tickets per match, for a maximum of 10 matches during the tournament. Fifa said it would operate a resale marketplace in an effort to avoid scalping.

    James Webb Space Telescope reveals ghostly dust rings: This “dead” star surprises astronomers |

    The James Webb Space Telescope (JWST) has captured astonishing new images of the planetary nebula NGC 1514, unveiling ghostly, infrared-bright rings around a dying star system located approximately 1,500 light-years from Earth. These structures, seen in unprecedented detail, provide astronomers with an extraordinary glimpse into the complex history and evolution of this stellar remnant.The findings, published in The Astronomical Journal under the title “JWST/MIRI Study of the Enigmatic Mid-infrared Rings in the Planetary Nebula NGC 1514,” reveal details never seen before. They allow scientists to study the turbulent 4,000-year history of the nebula and raise intriguing questions about the formation and behaviour of such celestial structures.

    Unveiling NGC 1514: James Webb Space Telescope shows infrared rings of dying star

    NGC 1514 was first discovered in 1790 by William Herschel, who observed its hazy glow surrounding a single star, a finding that challenged 18th-century ideas about nebulae. Over the centuries, astronomers repeatedly imaged the nebula, each time uncovering new layers of complexity.In 2010, NASA’s WISE (Wide-field Infrared Survey Explorer) detected a pair of infrared rings invisible in optical light. However, their precise structure and composition remained elusive-until the advent of JWST. Using the Mid-Infrared Instrument (MIRI), astronomers led by Michael Ressler of NASA’s Jet Propulsion Laboratory captured unprecedented images of the rings, showing fine-grained clumps, filaments, and turbulent features within the structures.

    Inside NGC 1514: How a binary star system shapes ghostly rings

    At the core of NGC 1514 lies a binary star system: a white dwarf and a giant companion star. The now-dead star expelled its outer layers as it evolved into a white dwarf, forming the glowing nebula. Its companion orbits closely, likely interacting gravitationally to shape the nebula’s peculiar hourglass structure.JWST’s images reveal a three-dimensional, pinched hourglass envelope, with the rings embedded across its midsection. The rings display asymmetries and unusual dust patterns, hinting at intense past interactions between the stars and complex processes that continue to puzzle astronomers.

    JWST reveals unique thermal dust emission in NGC 1514

    One of the most surprising discoveries is the nature of the rings’ emission. Unlike other planetary nebulae, which often show signals from molecules like polycyclic aromatic hydrocarbons (PAHs) or molecular hydrogen, over 98% of the light from NGC 1514’s rings comes from thermal radiation emitted by cool dust grains.This discovery suggests that the rings are fragile and structurally unique, and their formation mechanisms remain poorly understood. The striking clarity of JWST’s mid-infrared images emphasises the telescope’s transformative ability to reveal hidden geometries in complex nebulae.

    How JWST transforms our understanding of NGC 1514 and dying star

    NGC 1514 has evolved from a curious fuzzy patch in 18th-century telescopes to a scientific Rosetta Stone for understanding stellar death. The nebula’s symmetrical, ghostly rings challenge conventional theories about the final stages of stellar evolution and highlight the intricate interactions within binary star systems.These observations underscore JWST’s crucial role in expanding our understanding of planetary nebulae and the dynamic processes shaping them. Even as astronomers uncover more about NGC 1514, the nebula continues to redefine our knowledge of dying stars and cosmic evolution.
