An algorithm has spotted a nearly 600-foot, potentially hazardous asteroid near Earth. The tool is intended to find dangerous objects in Earth’s vicinity, to allow scientists to better track them and understand any threat they might pose. The new discovery is the system’s first detection of a “potentially hazardous” asteroid, a term that is used for those rocks that are near enough and possibly threatening enough to cause a danger to Earth. An asteroid gets the designation if it is within about 5 million miles of Earth’s orbit. The asteroid, known as 2022 SF289, does not pose any threat to Earth for the foreseeable future. Its closest approach brings it 140,000 miles from Earth – closer to us than the Moon, but still far enough away to be safe. But the creators of the algorithm said that it showed that the system could be used to detect others in the future – some of which may pose a threat to life on Earth. “By demonstrating the real-world effectiveness of the software that Rubin will use to look for thousands of yet-unknown potentially hazardous asteroids, the discovery of 2022 SF289 makes us all safer,” said scientist Ari Heinze, the principal developer of the algorithm, known as HelioLinc3D. Astronomers are looking forward to switching on the Vera C. Rubin Observatory, in Chile, in 2025. It will allow for a much more detailed view of the night sky. They hope that it can be used to spot more potentially hazardous asteroids, or PHAs. But the extra detail will also make more work for those poring through the data to find them, and so algorithms will be important to helping that work. HelioLinc3D is one such algorithm, and was built specifically to find asteroids within the Rubin observatory’s dataset. Though the equipment is not yet switched on, its creators looked to test whether it would successfully be able to find asteroids when it is looking through that data. The discovery of 2022 SF289 suggests that it will be. It was found in data from the ATLAS survey, based in Hawaii. ATLAS had actually seen the object three times on four separate nights, but an asteroid has to be seen four times on one night to be identified as a near-Earth object. “Any survey will have difficulty discovering objects like 2022 SF289 that are near its sensitivity limit, but HelioLinc3D shows that it is possible to recover these faint objects as long as they are visible over several nights,” said Denneau. “This in effect gives us a ‘bigger, better’ telescope.” Until now it had also been missed because it was passing in front of the busy and bright stars of the Milky Way. But scientists were able to confirm the existence of the object by looking back through data when they knew where to look. Scientists are aware of 2,350 PHAs already, but expect there are 3,000 out there waiting to be found. “This is just a small taste of what to expect with the Rubin Observatory in less than two years, when HelioLinc3D will be discovering an object like this every night,” said Rubin scientist Mario Jurić, director of the DiRAC Institute, professor of astronomy at the University of Washington and leader of the team behind HelioLinc3D. “But more broadly, it’s a preview of the coming era of data-intensive astronomy. From HelioLinc3D to AI-assisted codes, the next decade of discovery will be a story of advancement in algorithms as much as in new, large, telescopes.” Read More Reddit closes Place after obscene protests Kenya suspends eyeball-scanning crypto worldcoin Google warns Gmail users they could be about to lose their account Reddit closes Place after obscene protests Kenya suspends eyeball-scanning crypto worldcoin Google warns Gmail users they could be about to lose their account

Space travel might be a relatively modern phenomenon, but a pair of ancient human ancestors are getting to experience it too – albeit two million years after their death. The remains of a hominin species called Australopithecus sediba which date back two million years have been blasted into space as part of the Virgin Galactic’s spaceship, VSS Unity. The remains of a 250,000-year-old species named Homo naledi was also included in the craft, which was sent into space on September 8. Bone fragments from the two ancient skeletons were taken into orbit by Professor Lee Berger. They reached a height of around 50,000 feet by the VMS Eve mothership before being separated from the VSS Unity spaceship. Berger said: “The journey of these fossils into space represents humankind’s appreciation of the contribution of all of humanity’s ancestors and our ancient relatives. “Without their invention of technologies such as fire and tools, and their contribution to the evolution of the contemporary human mind, such extraordinary endeavors as spaceflight would not have happened.” Berger’s son, Matthew Berger, who was a part of the discovery of the remains as a child went on to explain the significance of the unusual cargo, saying: “These fossils represent individuals who lived and died hundreds of thousands of years ago, yet were individuals who likely gazed up at the stars in wonder, much as we do,” “I imagine they never could have dreamed while alive of taking such an incredible journey as ambassadors of all of humankind’s ancestors.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

TikTok does not want to compete with the BBC at Eurovision but instead “complement” and drive viewers towards its grand final coverage, a manager has said. The social media platform has partnered with contest organiser the European Broadcasting Union (EBU) and the BBC for the event in Liverpool, with busker pop-ups around the city, special coverage and gigs. James Stafford, TikTok’s general manager of marketing and operations for the UK, Ireland and Nordics, told the PA news agency the firm was doing “a lot of work” to promote the live TV broadcast. He said: “The hour before the live show on Saturday the BBC will be doing an exclusive live stream on TikTok that is designed to capture as much attention and audience from TikTok as possible, and direct them to go and tune in and watch the live broadcast. We would much prefer that we are a complement to those broadcasters and we can help them discover the next generation of fans who are going to tune in and watch Eurovision live on the BBC James Stafford “Now our goal here is not to compete with broadcasters for the live show. “We would much prefer that we are a complement to those broadcasters and we can help them discover the next generation of fans who are going to tune in and watch Eurovision live on the BBC.” Mr Stafford also sought to allay security concerns over TikTok’s involvement in the contest. TikTok is owned by Chinese internet company ByteDance, which argues that it does not share data with China’s government, but Beijing’s intelligence legislation requires firms to help the Communist Party when requested. Mr Stafford said: “The governments in Europe, including the UK, that have advised their employees not to use TikTok among other social apps on corporate devices is a purely precautionary measure, and it’s not the advice to ban the app in any of the markets. “We engage with all of our partners – the EBU, the governments that we partner with – to try and understand what their specific concerns are and share all of the information and be as transparent as possible about their concerns, so that we can move on from them.” Mr Stafford added that TikTok had had discussions with the EBU about the concerns. “Any one of our partners who has concerns, we are more than happy to be open and transparent with them about what they are,” he said. It came after Martin Osterdahl, the EBU’s executive supervisor for Eurovision, said the organisation plans to review its official partnership with TikTok – now in its second year – when the current contract ends. He told a press conference on Wednesday: “We review all our sponsorship agreements regularly and when they expire. We will do the same with TikTok. We will see what the situation is when that contract expires.” This year’s contest features a number of musicians with large followings on TikTok, including Norway’s Alessandra and Denmark’s Reiley. UK entrant Mae Muller, meanwhile, had chart success with her 2021 song Better Days after it went viral on the platform. Mr Stafford said that aside from last year’s UK entrant Sam Ryder being “incredibly talented” and “the most likeable person on Earth”, he also went into the 2022 contest with millions of TikTok fans. “I think a lot of other artists and delegations looked at that and saw the huge advantage there was to connect with fans and potential voters months before coming here,” he added. “So you will see that being a huge trend for the way various countries have selected their artists this year. “Of the 37 artists this year all of them are on TikTok and are really active and building their fan bases.” Darina Connolly, TikTok’s head of label and artist partnerships, said performers such as Israeli pop diva Noa Kirel, who has gone viral with a hand gesture dance move inspired by her song Unicorn, did not design their routines with TikTok in mind but such moments naturally translate to the app. She told PA: “I think all contestants are super focused on delivering the best performance that they can and I think easily a lot of that does translate to TikTok because we are an entertainment platform first and foremost, and people come to the platform to be entertained. “I wouldn’t say that the artists have done it specifically with TikTok in mind, but they have done it with entertainment in mind, which fits hand in hand with what we do as well.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Eurovision’s preparations for potential Russia cyberthreat ‘in good place’ UK-based tech company claims quantum computing ‘breakthrough’ Concert drone show organiser describes ‘nerve-wracking but exciting’ evening
