'The Witcher 3: The Wild Hunt' has hit the impressive milestone, eight years after its launch.

Astronomers have found a planetary system with six different worlds that orbit in a strange rhythm. The set of planets move around their star in a rhythmic beat, scientists say, staying synchronised in a kind of dance. The findings could help shed more light on how planets form and evolve, the researchers say. The star is smaller, and slightly dimmer than the Sun, and the six “sub-Neptunes” - possibly smaller versions of Neptune in our solar system - move in a cyclic rhythm. According to the experts, this orbital waltz repeats itself so precisely it can be readily set to music. The star, HD110067, is 100 light-years away in the northern constellation of Coma Berenices, and had perplexed researchers for years. Now scientists, including those at the University of Warwick, have revealed the true architecture of this unusual system using Nasa and European Space Agency (Esa) spacecraft. The analysis was led by University of Chicago scientist Dr Rafael Luque, who said: “This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the right conditions to support the existence of liquid water in their surfaces.” The first indication of planets orbiting the strange star system came in 2020, when Nasa’s Transiting Exoplanet Survey Satellite (Tess) detected dips in the star’s brightness which suggested planets were passing in between the star and the spacecraft. A preliminary analysis revealed two possible planets - one with a year (the length of time it takes to complete one orbit around the star) of 5.64 days, and another with an unknown period at the time. Two years later, Tess observed the same star again, and analysis ruled out the original interpretation but presented two additional possible planets. Much was still unknown about the planetary system, until scientists across the world - including those at the University of Warwick - joined the investigation. They used data from Esa’s Characterising Exoplanet Satellite (Cheops), hoping to determine the orbital periods of these faraway planets. While multi-planet systems are common in the Milky Way, those in a tight gravitational formation known as “resonance” are observed by astronomers far less often. In this case, the planet closest to the star makes three orbits for every two of the next planet out - called a 3/2 resonance - a pattern that is repeated among the four closest planets. Among the outermost planets, a pattern of four orbits for every three of the next planet out (a 4/3 resonance) is repeated twice. Thomas Wilson, from the Department of Physics at the University of Warwick, said: “By establishing this pattern of planet orbits, we were able to predict other orbits of planets we hadn’t yet detected. “From this we lined up previously unexplained dips in starlight observed by Cheops and discovered three additional planets with longer orbits. This was only possible with the crucial Cheops data.” Researchers say the planets - two to three times the size of Earth - are likely to have been performing this same rhythmic dance since the system formed billions of years ago. Dr Luque said: “We think only about 1% of all systems stay in resonance, and even fewer show a chain of planets in such configuration.” Experts say orbitally resonant systems are extremely important to find because they tell astronomers about the formation and subsequent evolution of the planetary system. Planets around stars tend to form in resonance but can easily have their orbits thrown around. For example, a very massive planet, a close encounter with a passing star, or a giant impact event can all disrupt the careful balance. Therefore, multi-planet systems preserving their resonance are rare. HD110067 is the brightest known system with four or more planets. Since those planets are all sub-Neptune-sized with likely larger atmospheres, it makes them ideal candidates for studying using the James Webb Space Telescope (JWST) and the Esa’s future Ariel telescope. Mr Wilson added: “All of these planets have large atmospheres - similar to Uranus or Neptune - which makes them perfect for observation with JWST. “It would be fascinating to test if these planets are rocky like Earth or Venus but with larger atmospheres - solid surfaces potentially with water. “However, they are all much hotter than Earth - 170C to 530C - which would make it very difficult for life to exist.” Hannah Osborne, a PhD student at UCL’s Mullard Space Science Laboratory and a co-author of the study, said: “The system itself is a key discovery for exoplanet science: because all six planets are in a resonant chain we know that the architecture of the system can’t have changed much since its formation, so by studying HD110067 we get a rare window into the past to understand how these types of systems may have formed and evolved.” The findings are published in the Nature journal.

A potentially dangerous setting on Android phones means that emergency phone lines are being pocket dialled, a Metropolitan Police officer has warned. Android devices have a setting called ‘Emergency SOS’ that is intended to make it easier for people to call for help. If a person presses the power button fives times or more, it starts a series of emergency actions like calling for help. Users can choose what that setting does. But by default the phone calls the police number, so that they will be alerted to any issue. The ease with which the setting can be activated means that 999 lines in the UK are getting called by accident, according Met Police chief superintendent Dan Ivey. The button is being pressed while people’s phones are in their pockets, further filling up already stretched emergency call handlers. He asked that people disable the feature to help reduce demand. He described the setting as a “problem”, though some users may opt to keep it active if they feel that it is likely to be used in an emergency. Mr Ivey said that on Saturday the Met Police had received an “unprecedented” 9,500 calls through 999, and 3,000 on non-emergency lines. Only 20 per cent of them had required police to be sent in emergency response mode, he said. “There is a problem with SOS auto mode on Android devices, so we are asking for your help,” Mr Ivey said, describing the issue. He asked that people turn off the feature by going to settings and then choosing “Emergency SOS”, where the feature can be turned off or changed so that it does not ring 999. He asked people to ensure they only call 999 when they need police urgently, on blue lights, in situations where there is a danger to life, someone is using or there is immediate threat of serious violence, or there is serious injury to a person or serious damage to a property. Mr Ivey was responding a to post from the London Ambulance Service in which it said it was also receiving historic numbers of calls. It said that on Monday it had received 7,751 999 calls, the highest since New Year’s Eve 2021, and also asked people to keep 999 for life-threatening emergencies only. The iPhone also has its own Emergency SOS feature, though its design may mean that it is less likely to be triggered by accident. On newer phones it is activated by pressing a volume and power button, and on older ones it is used by pressing the power button fives times; in both cases, however, it also requires users to then push across a slider that will actually activate the emergency call.

Sony has announced “Project Q”, a portable version of the PlayStation. The handheld system appears to be something like a PlayStation 5 controller, chopped in half with a screen placed in the middle of it. It works by streaming games over WiFi, the company said during a reveal. But it also suggested that customers will still need a PS5 in their home, and that the Project Q handheld will not be a standalone device. “We will launch a dedicated device that enables you to stream any game from your PS5 console using Remote Play over Wi-Fi,” said PlayStation boss Jim Ryan. “Internally known as ‘Project Q,’ it has an 8-inch HD screen and all of the buttons and features of the DualSense wireless controller.” That divided controller will have all the same “buttons and features” of the controller from the PS5, Sony said. That includes its adaptive triggers and haptic feedback. It will also have a screen that can show up to 1080p resolution at 60 frames per second, the company said. The headset is due to be announced later this year. Sony gave no further information about when that would be, how much it would cost, or even whether “Q” would be its eventual name. The system is not a devoted handheld device, like the Nintendo Switch or the Steam Deck. Nor is it specifically for streaming games over the internet, which would be part of a long-rumoured push into cloud gaming from PlayStation. Instead, it appears to be intended as a way of playing PlayStation games in other parts of the house. Users must not only have a PS5 also connected to the WiFi – which will be accessed through that Remote Play service – but also have the game they want to play installed on that console. Other services already offer the ability to play Remote Play games on handheld devices. Android and iPhones can use that same service, and can pair with controllers.
