Astronomers have finally figured out the source of the brightest explosion ever recorded
Astronomers have finally figured out the source of the brightest explosion ever recorded
Astronomers believe they might have found the source of the brightest explosion ever in space. The record-breaking explosion recorded in October 2022 was the most powerful ever seen, leaving equipment and instruments struggling to measure it as it pointed directly at planet Earth. The bright gamma-ray burst is officially called GRB 221009A and when it first went off, scientists were left scrabbling to point telescopes in its direction to record it. The explosion has affectionately been nicknamed BOAT, standing for “brightest of all time”, and was caused by the death of a large star located 2.4 billion light-years away – relatively close in terms of space activity. The star collapsed into a black hole after ejecting its outer envelope, causing this huge, bright explosion comprised of gamma rays, producing not only a narrow structured jet but with an additional outflow of gas. Sign up to our free Indy100 weekly newsletter This “exceptionally rare event” surprised astronomers, who had not predicted the existence of gas, and certainly provides plenty of new information around the question of how black holes form. The study’s lead author and astronomer from George Washington University, Brendan O'Connor, explained: “GRB 221009A represents a massive step forward in our understanding of gamma-ray bursts, and demonstrates that the most extreme explosions do not obey the standard physics assumed for garden variety gamma-ray bursts.” He continued: “GRB 221009A might be the equivalent Rosetta stone of long GRBs, forcing us to revise our standard theories of how relativistic outflows are formed in collapsing massive stars.” The huge and long-lasting blast measured up to 18 teraelectronvolts which is a staggering record for a gamma-ray burst, leaving scientists to hypothesise that it was a supernova.

How tech could turn our homes into renewable energy power stations
How tech could turn our homes into renewable energy power stations
In 1866, Napoleon III was presented with a solar-powered device that its inventor claimed could provide inexhaustible energy. The Emperor of France was so impressed by Augustin Mouchot’s Solar Concentrator that he granted the maths teacher funding to continue its development. The success of Mouchot’s invention – which was the size of a small house – meant solar energy started to be taken seriously as a potential alternative to coal, and scientists got to work on improving and adapting the technology for residential applications. Within a few decades, thousands of homes across the US were fitted with solar water heating systems that could heat homes, warm food and wash clothes, however the oil boom in the 20th century saw the popularity of clean energy collapse. It took until the 1973 oil crisis and soaring prices for solar to regain mainstream attention, and 50 years of technological advances later we may now be on the cusp of realising the revolutionary potential seen by the early pioneers of renewable energy. Recent breakthroughs have made solar panels both cheaper and more efficient, while researchers claim to now be close to creating commercially viable alternatives that could transform homes into fully self-sufficient power stations. These new technologies are finally making it possible to move away from traditional energy reliance, transforming the concept of living off-grid from an alternative lifestyle choice to a realistic solution for a sustainable future. So what are these new technologies, and what might a solar-powered home look like in the next few years? Photovoltaic windows The off-grid solar market is predicted to be worth $394 million by 2030, but this may be a low estimate if solar-powered windows finally break into the commercial market. Last year, a team from École Polytechnique Fédérale de Lausanne in Switzerland achieved a new efficiency record for dye-sensitised solar cells (DSCs), opening up new commercial possibilities for see-through solar panels. The transparent properties of DSCs make them suitable for use in windows, greenhouses and glass facades, offering a theoretical price/performance ratio that is capable of competing with fossil fuel electrical generation. Photovoltaic windows have already been installed in the SwissTech Convention Center, but the latest efficiency record could precede a much wider spread roll out. Solar-powered paint The Sun beams enough energy to Earth in just one hour to power the whole planet for an entire year, yet less than 10 per cent of the global electricity supply comes from solar energy. One of its limitations is that solar panels require roofs or available land – but what if it was possible to transform entire buildings into electricity generators? Scientists claim that solar paint could achieve this at a relatively low cost in the near future. The technology involves photovoltaic quantum dots that capture light and turn it into electric current. Theoretically, these dots could be 11 per cent more efficient than traditional solar panels. A longer-term prospect is spray-on solar cells that use a liquid form of the so-called miracle material perovskite, which researchers at the University of Sheffield say could be used in “practical mass applications” in the coming years. Combined with solar windows, the technology could mean that every single surface of a building that is touched by the Sun could generate power. Solar trees and battery breakthroughs There are more than a million acres of private gardens in the UK, according to the Office for National Statistics, though the space taken up by solar panels currently make them an unpopular option for most homeowners. UK startup SolarBotanic Trees is aiming to change this with a bio-inspired design that features a shaded canopy with integrated seating, heating and outlets. Speaking to The Independent earlier this month, SolarBotanic Trees chief executive Chris Shelley said the first installations are already planned in Oxford next year. “The idea is to put solar panels on a domed surface like the canopy of a tree, and then place a battery storage system in the trunk,” he said. “The trees could go in people’s gardens to supplement rooftop solar panel setups, or several of them could even meet the annual electrical requirement of a medium-sized house.” The solar trees address the need for battery systems that can continue to supply power when the Sun is not shining. Several companies already offer battery packs for homes, most notably Tesla’s Powerwall that has been installed in more than half a million homes around the world. At Tesla’s Investor Day event earlier this year, the company projected that it will take $10 trillion to achieve a “sustainable energy civilisation”, but will require less than 0.2 per cent of the Earth’s surface to achieve. Renewables expert Dr Brian Azzopardi believes the “remarkable pace” of battery and solar advances over the last few years means individuals can already reduce their dependence on energy grids and look towards a more sustainable way of living. “It has revolutionised the renewable energy sector and opened up unprecedented opportunities for individuals to become increasingly self-sufficient with their energy needs,” Dr Azzopardi, who chairs the Foundation for Innovation and Research at the Malta College of Arts, Science and Technology, tells The Independent. “As battery technologies continue to evolve, becoming more affordable and efficient, the possibility of achieving a self-sufficient lifestyle ‘off-the-grid’ becomes increasingly feasible for a wider range of people.” How long until we see off-grid solar homes on a significant scale? In the same way that some developing countries and communities skipped landlines and went straight to mobile phones, it may be communities with no access to a power grid that benefit most from the emerging technology. One startup targeting under-served markets is Zola Electric, which offers “electrical infrastructure in a box” for places without power. It involves a solar panel and battery setup capable of powering a home, with company CEO Bill Lenihan describing it as a “game-changer” for the roughly 3 billion people living without affordable or reliable energy. “Our solutions are installed in homes, businesses, schools and hospitals in 10 countries across four continents, serving over two million customers,” he told The Independent. “They deliver distributed, clean, digital energy solutions for those that need it most.” For developed countries, achieving self-sufficient living with clean energy first requires electrifying all energy – from gas stoves to fuel-powered cars. Mark Jacobson, a professor of civil and environmental engineering at Stanford University, says that recent technological advances and incentivised roll-outs mean it already makes economic sense to transform homes into renewable power stations. “Costs have declined so much in recent years, and tax credits are so abundant, that most homeowners can readily install home solar and battery systems,” Professor Jacobson, who detailed how he made the transition in his 2023 bookNo Miracles Needed: How Today’s Technology Can Save Our Climate and Clean Our Air, told The Independent. “I don’t pay any energy bills, generate 120 per cent of the electricity I consume – selling the rest back to my utility – and have paid back the entire solar plus battery system in six years. My energy is free for the next 25 years.” Read More Electric car drives for 100 hours non-stop on futuristic road Massive mineral deposit discovery could meet global battery and solar panel demand ‘for next 100 years’ Geothermal power: Clean energy beneath our feet that could help UK ditch fossil fuels ‘It’s like having your legs broken’: What it’s like to fly as a disabled traveller In the battle of authors vs robots, the entire craft of writing is at stake

Meta sued over ‘open secret’ of ‘pursuing’ and signing up millions of underage users
Meta sued over ‘open secret’ of ‘pursuing’ and signing up millions of underage users
Facebook‘s parent company Meta disabled only a small fraction of the over one million reports it received of underage users on Instagram since early 2019, a lawsuit filed by 33 US states reportedly said. The newly unsealed legal complaint accused the tech giant of carrying an “open secret” that it had millions of users under the age of 13, and that Instagram “routinely continued to collect” their personal information such as location without parental permission. The complaint stated that within the company, Meta’s actual knowledge that millions of Instagram users were under the age of 13 was an “open secret” that was routinely documented, rigorously analyzed and confirmed, and zealously protected from disclosure to the public, according to a New York Times report. Last month, attorneys general from 33 states, including New York’s AG Letitia James, filed a lawsuit against Meta alleging that the tech giant designed harmful features contributing to the country’s youth mental health crisis. The lawsuit alleged Meta created addictive and “psychologically manipulative” features targeting young people while assuring the public falsely that the platform was safe to use. “Meta has profited from children’s pain by intentionally designing its platforms with manipulative features that make children addicted to their platforms while lowering their self-esteem,” Ms James said. Meta’s spokesperson responded to the lawsuit, saying that the company was committed to providing teens with “safe, positive experiences online,” and that it had already introduced “over 30 tools to support teens and their families” such as age verification and preventing content promoting harmful behaviours. “We’re disappointed that instead of working productively with companies across the industry to create clear, age-appropriate standards for the many apps teens use, the attorneys general have chosen this path,” the spokesperson added. However, a significant portion of the evidence provided by the states was obscured from public view via redactions in the initial filing. The new unsealed complaint filed last week provided fresh insights from the lawsuit, including the accusation that Instagram “coveted and pursued” underage users for years and that Meta “continually failed” to make effective age-checking systems a priority. The lawsuit reportedly argued that Meta chose not to build effective systems to detect and exclude underage teen users, viewing them as a crucial next generation demographic it needed to capture. It also accused the tech giant of “automatically” ignoring some reports of under 13 users and allowing them to continue using the platform while knowing about such cases via the company’s internal reporting channels. The company responded that the now publicly revealed complaint “mischaracterizes our work using selective quotes and cherry-picked documents.” It said verifying the ages of its users was a “complex” challenge especially with younger people who likely do not have IDs or licenses. Meta recently said it supports federal legislation requiring app stores to get parents’ approval whenever their teens under 16 download apps. “With this solution, when a teen wants to download an app, app stores would be required to notify their parents, much like when parents are notified if their teen attempts to make a purchase,” the company said. “Parents can decide if they want to approve the download. They can also verify the age of their teen when setting up their phone, negating the need for everyone to verify their age multiple times across multiple apps,” it said. The tech giant holds that the best solution to support young people is a “simple, industry-wide solution” where all apps are held to the same standard. “By verifying a teen’s age on the app store, individual apps would not be required to collect potentially sensitive identifying information,” Meta recently said.
