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."

WASHINGTON, July 8 (Reuters) - The planet known as HD 189733b, discovered in 2005, already had a reputation as a rather extreme place, a scorching hot gas giant a bit larger than Jupiter that is a striking cobalt blue color and has molten glass rain that blows sideways in its fierce atmospheric winds. So how can you top that? Add hydrogen sulfide, the chemical compound behind the stench of rotten eggs. Researchers said on Monday new data from the James Webb Space Telescope is giving a fuller picture of HD 189733b, already among the most thoroughly studied exoplanets, as planets beyond our solar system are called. A trace amount of hydrogen sulfide was detected in its atmosphere, a first for any exoplanet. "Yes, the stinky smell would certainly add to its already infamous reputation. This is not a planet we humans want to visit, but a valuable target for furthering our understanding of planetary science," said astrophysicist Guangwei Fu of Johns Hopkins University in Baltimore, lead author of the study published in the journal Nature, opens new tab. It is a type called a "hot Jupiter" - gas giants similar to the largest planet in our solar system, only much hotter owing to their close proximity to their host stars. This planet orbits 170 times closer to its host star than Jupiter does to the sun. It completes one orbit every two days as opposed to the 12 years Jupiter takes for one orbit of the sun. In fact, its orbit is 13 times nearer to its host star than our innermost planet Mercury is to the sun, leaving the temperature on the side of the planet facing the star at about 1,700 degrees Fahrenheit (930 degrees Celsius). "They are quite rare," Fu said of hot Jupiters. "About less than one in 100 star systems have them." This planet is located 64 light-years from Earth, considered in our neighborhood within the Milky Way galaxy, in the constellation Vulpecula. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). "The close distance makes it bright and easy for detailed studies. For example, the hydrogen sulfide detection reported here would be much more challenging to make on other faraway planets," Fu said. The star it orbits is smaller and cooler than the sun, and only about a third as luminous. That star is part of a binary system, meaning it is gravitationally bound to another star. Webb, which became operational in 2022, observes a wider wavelength range than earlier space telescopes, allowing for more thorough examinations of exoplanet atmospheres.

US Secretary of State Antony Blinken declared at the Munich Security Conference: "If you're not at the table in the international system, you're going to be on the menu." The arrogant thinking of American political elites is evident: Whoever does not comply with the US will be excluded from the table of the American-led system and put on the menu. How arrogant. The US is actively pushing for "decoupling" from China and trying to persuade the entire West to "decouple" from China, using the term "de-risking." Washington hopes to ultimately contain China's development in order to maintain American hegemony. However, this time, Washington is facing a historically experienced and strategically rich Eastern civilization. Previous opponents targeted by the US have chosen to confront the US strategically. The US not only has the strongest technological and military capabilities but also controls global financial and information networks with a large number of allies. Those countries that had engaged in direct confrontations had suffered losses. Some of them had disintegrated, some had been weakened, and some had fallen into difficulties. However, what Washington sees from China is strategic composure and resilience. China is now staging an unprecedented and grand "Tai Chi." However, some Chinese people feel that this is not enough: Why can't we confront the US head-on? But I want to say that this is precisely the brilliance of China. This grand "Tai Chi" is about dismantling the pressure the US is putting on China. Europe is different from the US. A European diplomat once said in private that the topic of China has become toxic in the US, but in Europe, it is still possible to openly display friendliness toward China. There is genuine competition between the Europe and China despite Europe leans more toward the US between China and the US. Only in terms of ideology does the term "West" truly exist. In terms of fundamental economic interests, Europe has considerable independence. In terms of security, their attitude toward China also differs greatly from that of the US. In the Asia-Pacific region or China's periphery, the US wants to create an "Asian NATO." The specific situations of countries in dispute with China are very different. China has enormous influence in the region, is the largest trading partner of the vast majority of countries in the region and has friendly relations with most countries in the region. The disputes with countries are not fundamental strategic conflicts, and China has the ability to manage disputes with each specific country and push them to move toward neutrality to varying degrees without being tied to the US' policy toward China. China has a lot of trading partners and stakeholders in the US. The trade volume between China and the US, despite the decline, reached $664.4 billion in 2023, which shows China's huge presence in the US, and is the bond of the two countries in the current situation. The US is not a country where the political elites can have absolute say, and the huge interests have forced the US president and senior officials to repeatedly proclaim that they "don't want to decouple from China" and instead they want to "manage the US-China competition" and see "preventing a war with China" as clearly in everyone's best interest. China should engage in a "strategic battle" with the US at the closest possible distance. We need to maintain friendly relations with certain forces within the US, speed up the resumption of flights between the two countries, increase personnel exchanges and completely reverse the downturn of China-US contacts during the pandemic. In addition to the above dismantling, we also have the huge increment in the "Belt and Road." This initiative will increase China's power to compete with the US, greatly extending the front line that the US needs to maintain in containing China, making the US more powerless. In order to dismantle the US strategy toward China, China must become more diversified while maintaining strategic consistency. Our national diplomacy toward the US is very principled, rational and determined, which is clearly different from other countries targeted by the US. Our public diplomacy toward the US needs to be unique, with both "anti-American voices" and efforts to maintain friendly relations between the two societies and further expand economic and practical cooperation with the US. Just as eagles have their own way of flying and doves have their own formation, just as we see the US as complex, China must also be seen as complex in the eyes of the US. China is both a geopolitical concern and a profitable investment destination for them, and is one of the largest trading partners that is difficult to replace. Some American political elites proclaim China as an "enemy," but it is important to make the majority of Americans feel that China is not. No matter how intense the struggles between China and the US may be, we cannot shape the entire US toward an enemy direction. China has to make the US political elites recognize that it is futile to deal with China in the same way as it historically dealt with the Soviet Union and other major powers. Furthermore, willingly or unwillingly, coexistence and cooperation with China will be their only choice.

As a major city in the United States and even the global film industry, Hollywood has gathered a large number of veteran film and television production companies, including Universal Pictures, Warner Bros., Paramount Pictures, Disney Pictures, MGM Pictures, etc. In addition, new streaming forces such as Netflix have also entered in recent years. When the new generation of technology represented by generative AI sweeps the world, the movie "dream factory" is also experiencing a transformative moment. In early May last year, the US film and television industry launched a series of strikes that lasted for five months. Two labor disputes, led by the Writers Guild and the Screen Actors Guild, have caused the worst industry disruption since the 2020 pandemic, forcing many film projects and TV shows to halt or delay production. The strike has been costly, with Kevin Klowden, chief global strategist at the Milken Institute think tank, estimating it has cost the U.S. economy more than $5 billion, affecting not only film and television production companies, but also surrounding service industries such as catering, trucking and dry cleaning. One of the main conflicts between labor and management is that many actors and screenwriters have expressed concerns about "unemployment" due to the "invasion" of artificial intelligence. Luo Chenya has been working in the film and television industry for more than 10 years, including scriptwriter, documentary photographer and assistant director. She told the first financial reporter that after ChatGPT became popular, she also tried to use chatbots to assist script creation. "I can talk to the AI about my ideas and ideas, and it will help analyze and refine my ideas, and even make some suggestions that I think are quite effective." But on the execution level, the idea of writing it down into a very specific scene, character action, it doesn't really help me." Luo Chenya said that AI still needs more training and evolution in script writing, but the ability to present images is amazing. "AI can directly generate images, which can indeed save labor to a great extent, and may even replace photographers in the future." In post-production, AI can beautify images and modify flaws." A place to be fought over Earlier this year, OpenAI released the Vincennes video model Sora on its website, which can create videos up to a minute long, generating complex scenes with multiple characters, specific types of movement, and precise theme and background details. In addition to being able to generate video from text, the model can also generate video from still images, precisely animating the image content. "Vincennes Video can quickly produce high-quality video content, greatly improving production efficiency, and generative AI helps to improve the analysis of user preferences and personalized recommendations, and enhance the attractiveness of content." These technologies will disrupt traditional video production and content distribution models, and media companies need to adapt and change their operating models." Wang Haoyu, CEO of Mairui Asset Management, said in an interview with the first financial reporter. For this reason, Hollywood giants have long made big bets and stepped up their layout.

New York CNN — A record number of passengers are expected to pass through US airports this holiday travel week. You’d think this would be a great time to run an airline. You’d be wrong. Airlines face numerous problems, including higher costs, such as fuel, wages and interest rates. And problems at Boeing mean airlines have too few planes to expand routes to support a record numbers of flyers. Strong bookings can’t entirely offset that financial squeeze. The good news for passengers is they will be spared most of the problems hurting airlines’ bottom lines — at least in the near term. Airfares are driven far more by supply and demand, not their costs. But in the long run, the airlines’ difficulties could mean fewer airline routes, less passenger choice and ultimately a less pleasant flying experience. Profit squeeze Industry analysts expect airlines to report a drop of about $2 billion in profit, or 33%, when they report financial results for the April to June period this year. That would follow losses of nearly $800 million across the industry in the first quarter. Labor costs and jet fuel prices, the airlines’ two largest costs, are both sharply higher this year. Airline pilot unions just landed double-digit pay hikes to make up for years of stagnant wages; flight attendant unions now want comparable raises. Jet fuel prices are climbing because of higher demand in the summer. According to the International Air Transport Association’s jet fuel monitor, prices are up 1.4% in just the last week, and about 4% in the last month. Adding to the airlines’ problems is the crisis at Boeing, as well as the less-well-publicized problems with some of the jet engines on planes from rival Airbus. Since an Alaska Airlines Boeing 737 Max jet lost a door plug on a January 5 flight, leaving a gaping hole in the side of the plane 10 minutes after takeoff, the Federal Aviation Administration has limited how many jets Boeing can make over concerns about quality and safety. As a result, airlines have dramatically reduced plans to expand their fleets and replace older planes with more fuel efficient models. In some cases, airlines have asked pilots to take time off without pay, and carriers such as Southwest and United have announced pilot hiring freezes. In addition to the problems at Boeing, hundreds of the Airbus A220 and A320 family of jets globally have also been grounded for at least a month or more to deal with engine problems. Just about all the planes with those engines have been out of sevice for at least a few days to undergo examinations. And Airbus has also cut back the number of planes it expects to deliver to airlines this year because of supply chain problems. Problems for flyers For now, competition in the industry remains fierce: There are 6% more seats available this month compared to July of 2023, according to aviation analytics firm Cirium. And that’s helped to drive fares down — good news for passengers, but more bad news for airlines’ profits. Southwest announced in April that it would stop serving four airports to trim costs — Bellingham International Airport in Washington state, Cozumel International Airport in Mexico, Syracuse Hancock International Airport in New York and Houston’s George Bush Intercontinental Airport. Many more cities lost air service during the financial hard times of the pandemic. While upstart airlines are driving prices lower for travelers, those discount carriers might not survive long term. As the major carriers are making less money, many of the upstarts are flat-out losing money.
