Twitter has threatened Meta with legal action over its new social media platform “Threads,” claiming that they have created a “copycat” platform and hiring former Twitter staff to do so. Meta, the parent company of Instagram and Facebook led by Mark Zuckerberg, revealed Threads on Wednesday, a text-based app partnering with Instagram that is similar to Twitter and other apps.

Astronomers have spotted the moment a black hole "turned on". While looking for the collision of a neutron star with another object, which should result in a kilonova (an explosion which reddens then fades over time), they stumbled upon an event which remained extremely bright. They soon worked out this light was because of supermassive black hole called J221951-484240 which had been on for around 10 months. But then they had to work out what had caused it, and got stuck between two causes, “J221951 is consistent with being nuclear, so the scenarios we are being left are a tidal disruption event or an active galactic nucleus,” lead author Dr Samantha Oates said as she presented the research at the National Astronomy Meeting 2023. “Looking at the spectrum it's consistent with both categories.” Sign up to our free Indy100 weekly newsletter A tidal disruption event (TDE) takes place when a star or a gas cloud gets too close to a supermassive black hole. The material is ripped apart, and begins to shine as the black hole feeds Alternatively, it could be an active galactic nucleus (AGN), the phase of a supermassive black hole where it is consistently feeding in a frenzy. “We hope in future to distinguish between these two scenarios,” Dr Oates concluded.

July's Buck supermoon could be seen around the world lighting up the skies at the start of this week, but incredible new footage is showing the sheer scale of the phenomenon. A plane flying over the skies of Oregon is going viral after being filmed getting completely eclipsed by the moment. In the footage of the giant moon, the tiny plane goes flying past, and looks absolutely minuscule in comparison to the planet. Click here to sign up for our newsletters

There are eight planets in our solar system – plus poor old Pluto, which was demoted in 2006 – but what if there were more? Turns out that might be the case. Astronomers have calculated there is a 7 per cent chance that Earth has another neighbour hiding in the Oort cloud, a spherical region of ice chunks and rocks that is tens of thousands of times farther from the sun than we are. “It’s completely plausible for our solar system to have captured such an Oort cloud planet,” said Nathan Kaib, a co-author on the work and an astronomer at the Planetary Science Institute. Sign up to our free Indy100 weekly newsletter Hidden worlds like this are “a class of planets that should definitely exist but have received relatively little attention” until now, he said.. If a planet is hiding in the Oort cloud, it’s almost certainly an ice giant. Large planets like Jupiter and Saturn are generally born as twins. They have huge gravitational pulls of their own, however, and sometimes destabilise one another. That could have led to a planet to be nudged out of the solar system entirely – or exiled to its outer reaches, where the Oort cloud resides. “The survivor planets have eccentric orbits, which are like the scars from their violent pasts,” said lead author Sean Raymond, researcher at the University of Bordeaux’s Astrophysics Laboratory. That means that the Oort cloud planet could have a significantly elongated orbit, unlike the near-perfect circle Earth tracks around the sun. Trouble is, when things are that far away, they’re pretty difficult to spot. “It would be extremely hard to detect,” added Raymond. “If a Neptune-sized planet existed in our own Oort cloud, there’s a good chance that we wouldn’t have found it yet,” said Malena Rice, an astronomer at MIT not involved in this work. “Amazingly, it can sometimes be easier to spot planets hundreds of light-years away than those right in our own backyard.” Time to crack out the telescope.

Researchers in China have developed an artificial intelligence tool capable of designing a working computer in under five hours. The team of 19 computer scientists from five different institutions made the AI breakthrough after setting out to prove that machines can create computer chips in a similar way to humans. The feat was performed 1,000 times faster than a human team could have achieved it, the researchers claimed, marking a major step towards building self-evolving machines. “Design activity... distinguishes humanity from other animals and traditional machines, and endowing machines with design abilities at the human level or beyond has been a long-term pursuit,” the scientists wrote in a paper detailing their research. “We present a new AI approach to automatically design a central processing unit (CPU), the brain of a computer, and one of the world’s most intricate devices humanity has ever designed.” The project involved the layout of an industrial-scale RISC-V CPU, capable of running the Linux operating system and achieving an accuracy of 99.99 per cent in validation tests. The AI bypassed the manual programming and verification process of the typical design cycle, which the researchers said “consumes more than 60-80 per cent of the design time and resources” of human teams. The AI was also able to autonomously make discoveries involving computer design, uncovering something called the von Neumann architecture, first invented in 1945. The overall performance of the CPU is relatively modest compared to modern computers, with the researchers saying it can perform at a similar level to a 1991 Intel 80486SX CPU. Developing the AI approach, however, has the potential to “reform the semiconductor industry by significantly reducing the design cycle”, the researchers said. The research is detailed in a study, titled ‘Pushing the limits of machine design: Automated CPU design with AI’. Leading AI chip maker Nvidia has previously used artificial intelligence to optimise its computer chip designs, publishing a new approach to AI-powered chip design in March that could significantly improve the cost and performance of CPUs.
