The Sun is extremely active right now, blasting the Earth with the biggest solar storms in 20 years. This is what it is doing to the rest of the Solar System. If you happened to look skywards on a few nights in May 2024, there was a good chance of seeing something spectacular. For those at relatively low latitudes, there was a rare chance to see the flickering red, pink, green glow of our planet's aurorae. A powerful solar storm had sent bursts of charged particles barrelling towards Earth and, as they bounced around in our planet's atmosphere, they unleashed spectacular displays of the Northern and Southern Lights. The dazzling displays of aurora borealis were visible far further south than they might normally be – and far further north in the case of aurora australis thanks to the power of the geomagnetic storm, the strongest in two decades. Although some people experienced only a faint, eerie glow, others were treated to a myriad of colour as far south as London in the UK and Ohio in the US. Reports even came in from just to the north of San Francisco, California. But while this spike in activity from the Sun left many on Earth transfixed by the light display it produced, it has also had a profound effect elsewhere in the Solar System. As most of us wondered at the colours dancing across the night's sky, astronomers have been peering far beyond to see the strange ways such intense bursts of particles affect other planets and the space between them. "The Sun can fire material outwards in any direction like a garden sprinkler," says Jim Wild, a professor of space physics at Lancaster University in the UK. "The effects are felt throughout the Solar System." Our Sun is currently heading towards, or has already reached, its solar maximum – the point in an 11-year cycle where it is most active. This means the Sun produces more bursts of radiation and particles from solar flares and events known as coronal mass ejections (CMEs). If these are sprayed in our direction, they can supercharge the Earth's magnetic field, causing magnificent aurorae but also posing problems for satellites and power grids. "Things really seem to be picking up right now," says Mathew Owens, a space physicist at the University of Reading in the UK. "I think we're about at solar maximum now, so we may see more of these kinds of storms in the next couple of years." Around the Sun, multiple spacecraft are observing this increase in activity up close. One of those, the European Space Agency's (Esa) Solar Orbiter, has been studying the Sun since 2020 on an orbit that takes it within the path of Mercury. Currently the spacecraft is "on the far side of the Sun as seen from Earth", says Daniel Müller, project scientist for the Solar Orbiter mission at Esa in the Netherlands. "So we see everything that Earth doesn't see." The storm that hit Earth in May originated from an active region of solar flares and sunspots, bursts of plasma and twisting magnetic fields on the Sun's surface, known as its photosphere. Solar Orbiter was able to see "several of the flares from this monster active region that rotated out of Earth's view", says Müller, bright flashes of light and darkened regions called sunspots on the Sun's surface. One of the goals of Solar Orbiter is "to connect what's happening on the Sun to what's happening in the heliosphere," says Müller. The heliosphere is a vast bubble of plasma that envelops the Sun and the planets of the Solar System as it travels through interstellar space. What Müller and his colleagues hope to learn more about is where the solar wind – the constant stream of particles spilling out from the Sun across the Solar System – "blows into the interstellar medium", he says. "So we are particularly interested in anything energetic on the Sun that we can find back in the turbulence of the solar wind." This particular cycle, cycle 25, appears to be "significantly more active than what people predicted", says Müller, with the relative sunspot number – an index used to measure the activity across the visible surface of the Sun – eclipsing what was seen as the peak of the previous solar cycle. The National Oceanic and Atmospheric Administration (Noaa) in the US had predicted a maximum monthly average of 124 sunspots a day in May, but the actual number was 170 on average, with one day exceeding 240, according to Müller. But the exact cause of the Sun's 11-year-long cycle and its variabilities remains a bit of a mystery. • Alien aurora: The strange displays that light up other worlds • Why Einstein was wrong about black holes • The Moon is slipping away from the Earth – and our days are getting longer The effects of these changes in solar activity, however, extend far across the Solar System. Earth is not the only planet to be hit by solar storms as they billow across interplanetary space. Mercury, the closest planet to the Sun, has a much weaker magnetic field than Earth – about 100 times less – and lacks a substantial atmosphere. But solar activity can cause the surface of the planet to glow with X-rays as solar wind rains down. Venus also lacks a substantial magnetic field, but the planet does still create auroras as the solar wind interacts with the planet's ionosphere. At Mars, the effect of solar activity is more obvious. Here, a Nasa spacecraft called Maven (Mars Atmosphere and Volatile Evolution) has been studying the planet's atmosphere from orbit since 2014. "We were on the declining side of solar cycle 24 [then]," says Shannon Curry, a planetary scientist at the University of Colorado, Boulder in the US and the lead on the mission. "We are now coming up on the peak of cycle 25, and this latest series of active regions has produced the strongest activity Maven has ever seen." Between 14 and 20 May the spacecraft detected exceptionally powerful solar activity reaching Mars, including an X8.7 – solar flares are ranked B, C, M, and X in order from weakest to strongest. Results from the event have yet to be studied, but Curry noted that a previous X8.2 flare had resulted in "a dozen papers" published in scientific journals. Another flare on 20 May, later estimated to be an even bigger X12, hurled X-rays and gamma rays towards Mars before a subsequent coronal mass ejection launched a barrage of charged particles in the same direction. Images beamed back from Nasa's Curiosity Rover on Mars revealed just now much energy struck the Martian surface. Streaks and dots caused by charged particles hitting the camera's sensors caused the images to "dance with snow", according to a press release from Nasa. Maven, meanwhile, captured glowing aurora as the particles hit the Mars' atmosphere, engulfing the entire planet in an ultraviolet glow. The flares can cause the temperature of the Martian atmosphere to "dramatically increase," says Curry. "It can even double in the upper atmosphere. The atmosphere itself inflates. The entire atmosphere expands dozens of kilometres – exciting for scientists but detrimental for spacecraft, because when the atmosphere expands there's more drag on the spacecraft." The expanding atmosphere can also cause degradation of the solar panels on spacecraft orbiting Mars from the increase in radiation. "The last two flares caused more degradation than what a third of a year would typically do," says Curry. Mars, while it has lost most of its magnetic field, still has "crustal remnant magnetic fields, little bubbles all over the southern hemisphere", says Curry. During a solar event, charged particles can light those up and excite particles. "The entire day side lights up in what we call a diffuse aurora," says Curry. "The entire sky glows. This would most likely be visible to astronauts on the surface." By the time solar storms reach further out into the solar system, they tend to have dissipated but can still have an impact on the planets they encounter. Jupiter, Saturn, Uranus, and Neptune all have aurorae that are in part driven by charged particles from the Sun interacting with their magnetic fields. But one of the key effects of solar activity on interplanetary space that astronomers are eager to study is something called "slow solar wind", a more sluggish, but denser stream of charged particles and plasma from the Sun. Steph Yardley, a solar astronomer at Northumbria University in the UK, says solar wind is "generally classed about 500km/s (310 miles/s)", but slow wind falls below this. It also has a lower temperature and tends to be more volatile. Recent work by Yardley and her colleagues, using data from Solar Orbiter, suggests that the Sun's atmosphere, its corona, plays a role in the speed of the solar wind. Regions where the magnetic field lines, the direction of the field and charged particles are "open" – stretching out into space without looping back – provide a highway for solar wind to reach high speeds. Closed loops over some active regions – where the magnetic field lines have no beginning and end – can occasionally snap, producing slow solar wind. The variability in the slow solar wind seems to be driven by the unpredictable flow of plasma inside the Sun, which makes the magnetic field particularly chaotic. The X-class flares and coronal mass ejections seen in May transformed the interplanetary medium as they flung out material across the solar system. Solar Orbiter detected a huge spike in ions moving at thousands of kilometres per second immediately after the 20 May flare. Computers on board other spacecraft – the BepiColombo probe, which is currently on a seven-year journey to Mercury, and Mars Express, in orbit around the Red Planet – both saw a dramatic increase in the number of memory errors caused by the high energy solar particles hitting the memory cells. The day after the coronal mass ejection, magnetometers on board the Solar Orbiter also saw large swings in the magnetic field around the spacecraft as a huge bubble of plasma made up of charged particles thrown out from by the event washed past it at 1,400km/s (870 miles/s). Increased solar activity is a boon for scientists. "If you track the number of papers produced by solar physicists, you can almost see an 11-year cycle in there," says Owens. "We are all more scientifically productive when there's a lot of activity to study." As the Sun continues into solar maximum, the Solar System will see more and more activity streaming from its surface. Yet while all the planets witness at least some of the activity, our planet bears the brunt more than most. "Earth is slightly unique in that space weather can have interesting effects on human technologies," says Wild. "There's an extra dimension here on Earth." Perhaps one day those anthropogenic effects might be felt elsewhere, too. "If you're going to fly to Mars and you have a six-month flight through the interplanetary environment, you're going to potentially suck up a lot of space weather events," says Wild. "How you protect your astronauts is an interplanetary issue that we need to get our heads around."

The tetraprism lens with 5x optical zoom currently exclusive to the iPhone 15 Pro Max could be headed to both the iPhone 16 Pro and iPhone 16 Pro Max, narrowing the gap between Apple's premium flagships. That's according to a new report from analyst Ming-Chi Kuo, who cites a recent earnings call with Apple lens supplier Largan. In the call, a spokesperson from Largan said "some flagship specifications will be extended to other models" in the second half of 2024, presumably in reference to the upcoming iPhone Pro models. "Apple is Largan’s largest customer, and Largan is also Apple’s largest lens supplier," Kuo said. "Therefore, the quote likely refers to the fact that the new iPhone 16 Pro and Pro Max will have a tetraprism camera in 2H24 (while only the iPhone 15 Pro Max had this camera in 2H23).” The report goes on to say that the tetraprism camera for the iPhone 16 Pro series won't be all that different from the one in the iPhone 15 Pro Max. While the lack of an upgrade is disappointing, it's not necessarily a bad thing as these kinds of lenses are already top-of-the-line. They represent a major increase over prior models’ zoom capabilities, and they're capable of offering more depth while still fitting into super-slim smartphones. That being said, Apple does appear to be revamping the main camera and ultra-wide camera on the iPhone 16 Pro Max. Evidence continues to mount that both iPhone 16 Pro models will share the same 5x optical zoom camera. Earlier this week, DigitTimes in Asia (via 9to5Mac) reported that Apple is set to ramp up orders for tetraprism lenses as it expands their use in its upcoming iPhone series. Industry sources told the outlet that Largan and Genius Electronic Optical were tapped as the primary suppliers. Apple would be wise to streamline its Pro-level iPhones with the same camera setup; then all customers have to consider with their choice of a new iPhone is the size and price. Of course, this should all be taken with a grain of sand for now until we hear more from Apple. It's still a while yet before Apple's usual September time window for iPhone launches. In the meantime, be sure to check out all the rumors so far in our iPhone 16, iPhone 16 Pro and iPhone 16 Pro Max hubs.

A spokesperson for the Ministry of Commerce (MOFCOM) on Monday rejected remarks from the EU Ambassador to China on the anti-subsidy investigation into Chinese electric vehicles (EVs). MOFCOM said China had expressed strong opposition through various channels since October 2023 and has always advocated for handling economic and trade frictions through dialogue and consultation in order to maintain the overall strategic partnership between China and Europe. EU Ambassador to China Jorge Toledo claimed on Sunday that the EU has been trying to engage with China for months regarding the imposition of tariffs on Chinese EVs but that China had only recently sought to initiate discussions. This is false, the spokesperson said. MOFCOM said that after the European Commission (EC) officially filed a case, Chinese Commerce Minister Wang Wentao sent a letter to European Commission Executive Vice-President Valdis Dombrovskis on October 24, 2023, expressing hope to resolve the case through dialogue and negotiation. On November 13, 2023, Wang sent another letter to the European side proposing negotiation suggestions. In February 2024, Wang met with Dombrovskis during the WTO's 13th Ministerial Conference face to face and proposed dialogue and negotiation with the European side. On May 19, 2024, Wang reiterated the hope for dialogue and negotiation to resolve the case in a letter to the European side. Additionally, Chinese technical experts have been sending signals to the European side regarding on-site inspections, hearings, and other channels since the case was filed, expressing willingness to resolve trade frictions through dialogue and negotiation. On the day the preliminary ruling was announced on June 12, Dombrovskis replied to Wang in a letter, expressing the desire for both sides to strengthen dialogue to resolve the case. On June 22, Wang held a video conference with Dombrovskis, and they agreed to start negotiations on the EU's anti-subsidy investigation into Chinese EVs. Subsequently, China sent a working group to Europe for negotiations on June 23, and multiple rounds of technical consultations were held simultaneously via video. MOFCOM said that China has shown the utmost sincerity and hopes that the European side will meet China halfway, show sincerity, and push forward the negotiation process to reach a mutually acceptable solution as soon as possible. China has always believed that trade protectionist measures are not conducive to the development of global green industries and automotive industry cooperation. Efforts should be made to adhere to dialogue and cooperation to promote economic green transformation, rather than creating divisions and disrupting global industrial and supply chains, MOFCOM said. China firmly opposes any unilateralism and protectionism that politicizes and weaponizes economic and trade issues, and will take all necessary measures to defend its own interests against any abuse of rules and suppression of China, MOFCOM added.

US politicians are advocating for steep tariffs, echoing the protectionist Fordney-McCumber Tariff of 1922. Despite potential international retaliation, risks to global economic rules and a shift from post-World War II principles, US politicians have promised to increase trade barriers against China, causing concerns for the sustainability of global economic harmony. A century ago, the Republican Congress passed the Fordney-McCumber Tariff of 1922. This post-World War-I effort to protect the US from German competition and rescue America's own businesses from falling prices sparked a global wave of tariff hikes. While long forgotten, echoes of Fordney-McCumber now reverberate across the US political landscape. Once again, politicians are grasping the tariff as a magic talisman against its own economic ills and to contain the rise of China. The Democratic Party of the 1920s opposed tariffs, because duties are harmful to consumers and farmers, but today both President Joe Biden and former President Donald Trump favor national delivery through protectionism. Trump promised that his second term, if elected, would impose 60-percent tariffs on everything arriving from China and 10-percent tariffs on imports from the rest of the world, apparently including the imports covered by 14 free trade agreements with America's 20 partners. He initially promised 100-percent tariffs on electric vehicles (EVs), but when Biden declared that he was hiking tariffs on EVs from China to 100-percent, Trump raised the ante to 200-percent. On May 14, 2024, the White House imposed tariffs ranging from 25 percent (on items such as steel, aluminum and lithium batteries) to 50 percent (semiconductors, solar cells, syringes and needles) and 100 percent (electric vehicles) on Chinese imports. US government officials offer "national security" and "supply chain vulnerability" as the justification for levying high tariffs. To deflect worries about inflation, US Trade Representative Katherine Tai declared, "first of all, I think that that link, in terms of tariffs to prices, has been largely debunked." Contrary findings by the United States International Trade Commission and a number of distinguished economists, as well as Biden's own 2019 statement criticizing Trump's tariffs - "Trump doesn't get the basics. He thinks tariffs are being paid by China… [but] the American people are paying his tariffs" - forced Tai's office to wind back her declaration. The fact that prohibitive barriers to imports of solar cells, batteries and EVs will delay the green economy carries zero political weight with Trump and little with Biden. Nor does either of them worry about the prospects of Chinese retaliation and damage to the fabric of global economic rules. Historical lessons - unanticipated consequences of the foolish Fordney-McCumber Tariff of 1922 and the Smoot-Hawley Tariff of 1930 - are seen as irrelevant by the candidates and their advisers. The US' lurch from its post-World War II free trade principles offers China a golden opportunity. On the world stage, China will espouse open free trade and investment. China will encourage EV and battery firms to establish plants in Europe, Brazil, Mexico and elsewhere, essentially daring the US to damage its own alliances by restricting third country imports containing Chinese components. Whether the fabric of global economic rules that has delivered astounding prosperity to the world will survive through the 21st century remains to be seen. Much will depend on the decisions of other large economic powers, not only China but also the European Union and Japan, as well as middle powers, such as Australia, Brazil, Chile, ASEAN and South Korea. Their actions and reactions will reshape the rules of the 21st century. If others follow America down this costly path, the world will become less prosperous and vastly more unpredictable. If they resist, the US risks being diminished and more isolated. The author is a non-resident Senior Fellow at the Peterson Institute of International Economics. bizopinion@globaltimes.com.cn

Koenigsegg Agera RS Chimera combines technologies from Agera RS, CC850, and Jesko. An Agera RS platform features the engine from the Jesko and the simulated manual gearbox from the CC850. Development took three years, thanks to software and hardware integration challenges. A "chimera," for the uninitiated, is described as a mythical creature whose anatomy comes from multiple animals, creating a hybrid of two or more creatures' best bits. It's also the name of the latest one-off creation from Koenigsegg, and it's certainly apt; the Koenigsegg Agera RS Chimera is an amalgam of technologies from the decade-old, record-breaking Agera RS, the fascinatingly innovative CC850, and the awe-inspiring Jesko - which just recently set four new acceleration records. There's also a hint of Regera in here, which had some impressive records of its own. As reported by Mr. JWW, the strictly one-off special edition was commissioned by FIA President Mohammed Ben Sulayem, and both he and one of Koenigsegg's engineers arrived at the same name. Let's take a closer look and see exactly why this is a hybrid, even though it's not electrified. Three Cars In One The Chimera was originally a regular Agera RS and one of several Koenigsegg megacars owned by Ben Sulayem, but he asked Christian and the team to initiate a special project on his behalf. Around the same time, the extraordinary Koenigsegg CC850 was revealed at Monterey Car Week 2022, introducing the innovative Engage Shift System (ESS). This was based on the already astonishingly fast nine-speed Light Speed Transmission, with new actuators and sensors added to enable the simulation of a manual transmission without a physical link between the shifter and the gearbox. Like the rest of the world, the FIA boss was enamored by this novel technology, and as a wealthy 'Egg collector, he asked for it to be put into his special Agera-based project. Christian pondered this and ultimately decided to fulfill the request, in the process turning Ben Sulayem's special edition into something of a development mule for the ESS. But unlike the CC850, the Chimera got the larger turbos of the Jesko, enabling around 1,280 horsepower on regular gas and up to 1,600 hp on E85. That means this is an Agera RS with a CC850 transmission and a Jesko engine. On paper, that sounds simple, but the reality was anything but... Three Shifting Experiences Took Three Years To Combine According to a video from YouTuber and Koenigsegg distributor Mr. JWW, this development process took three years and required the relocation of the battery, new mounts for the powertrain, new harnesses, new software and controllers, and even a new infotainment system. To ensure all the electronics worked seamlessly was a challenge, but then Ben Sulayem asked for another layer of intricacy, requesting that paddle shifters be added, like in the Jesko Absolut and Jesko Attack. In the CC850, you could only switch between the simulated manual mode and fully automatic shifts, but now, the Chimera's development has unlocked manually operable paddles, which have now been added as the only option you can add to a CC850. There was also significant relocation and redesigning of suspension components, with parts from the Jesko and the Regera forming the subframe and elements of the suspension, respectively. A new scoop for the new transmission's cooler was also added, but it looks like it was always planned. Christian von Koenigsegg says this is a true one-off, saying that it would be cheaper and easier to start something all-new from scratch than to mix new and old technologies again, and that it's simply "too much work" to tackle a retrofit project. The Chimera is not completed just yet, as there are still subtle elements to refine, such as the bite point of the clutch pedal, but these minor issues will surely be resolved soon. It's an amazing feat, combining three hypercars in one, and we can't even fathom how Koenigsegg will top this in the future, but we don't doubt that Christian and his team will continue to do just that.
