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."

Editor's Note: This year marks the 10th anniversary of the Belt and Road Initiative (BRI) proposed by Chinese President Xi Jinping. Through the lens of foreign pundits, we take a look at 10 years of the BRI - how it achieves win-win cooperation between China and participating countries of the BRI and how it has given the people of these countries a sense of fulfillment. In an interview with Global Times (GT) reporter Li Aixin, Erik Solheim (Solheim), former under-secretary-general of the United Nations and former executive director of the UN Environment Programme, recalled how the BRI helped shorten a previously long journey in Sri Lanka to a half-hour trip. "We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together," Solheim said. This is the 18th piece of the series. GT: How do you evaluate the role of the BRI in promoting development in participating countries over the past 10 years? Solheim: The BRI has been a major driver of development since it was announced by President Xi Jinping in Kazakhstan 10 years ago. The China-Laos Railway has connected landlocked Laos to the Chinese and European rail network, making it possible for Laos to sell more goods and welcome more tourists. Rail corridors in Kenya and from Djibouti to Addis Ababa connect the interior of Africa to the coast, bringing opportunities for much faster development in East Africa. The Bandung-Jakarta railway in Indonesia, Hanoi metro, roads and ports in Sri Lanka - there are great examples of good south-south and BRI projects in almost every corner of the world. GT: In your experience of traveling around the world, has any BRI-related story left a deep impression on you? Solheim: Yes, many! I'll just mention two. When I was chief negotiator in the Sri Lanka peace process 15 years ago, it took a long time to travel from the airport to Colombo, the capital of Sri Lanka. When I came back last year, it took half an hour on wonderful Chinese-built highways. Traveling through Mombasa, a coastal city in Kenya, you see a lot of poverty and run down houses. Then all of a sudden, a green, clean, well-run oasis opens up. It's the end station of the Nairobi-Mombasa railway which links the capital Nairobi to the coast. The rail station stands out and is showing the future for Kenya. GT: The EU proposed the Global Gateway, and the US proposed the Build Back Better World. What do you think are the similarities and differences between these projects and the BRI? Solheim: I really wish success for the Western initiatives. What developing nations ask for is a choice of good cooperation with both China and the West. Unfortunately, up to now, a number of the Western-led initiatives have been more like media events. They lack structure, secretariat, finances and clear direction. Nearly all nations in the world want to see close people-to-people relations, investment and political cooperation with both China and the West. No one wants to choose. GT: Some people from the West are talking about "de-coupling" and "de-risking." Both seem to be another way of saying "de-globalization." Do you think "de-coupling" and "de-risking" will affect the BRI? And what role will the BRI play in maintaining globalization? Solheim: Decoupling is probably the most unwise idea in the world today. It's outright dangerous. Facing climate change, environmental degradation, economic troubles, war in Ukraine and other places, and the threat of pandemics, we need more, not less, cooperation. We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together. Almost all developing countries have made BRI agreements with China. As an example, when President Xi met all the leaders of Central Asia recently in Xi'an, Northwest China's Shaanxi Province, they made a very ambitious declaration on future green cooperation between China and Central Asia. GT: You have previously said that the BRI is a fantastic vehicle to promote green global development, which can boost the economy and ecology at the same time. Could you elaborate on how you think the BRI has achieved development of the economy and ecology? Solheim: In the beginning there were too many fossil fuel projects among BRI programs. In the BRI International Green Development Coalition, we argued this should stop. When President Xi pledged to stop building new coal-fired power projects overseas, it was one of the most important environmental decisions ever. Also, it happened at a time when important BRI nations like Bangladesh, Kenya and Pakistan decided they could grow their economies and go green without coal. The BRI will in the next decade become the world's most important vehicle for green energy and green transport. We will see massive investments in solar and wind power, hydrogen, electric batteries and more. GT: How do you view China's goal of achieving harmony between humanity and nature in modernization? In what way is China's story in pursuing harmony between humanity and nature relevant to other countries? Solheim: China now covers between 60 percent and 80 percent of all major green technologies in the world - solar, wind, hydro, batteries, electric cars and high-speed rail. Companies like Longi, BYD and CATL are the world leaders in their sectors. More remarkably and maybe less noticed abroad, China is also a global leader in protecting nature. It's embarking upon one of the most massive national park programs, with a focus on Qinghai Province and Xizang Autonomous Region. China is by far the biggest tree planter in the world and the global leader in desert control in Kubuqi, Inner Mongolia and other places. China has been hugely successful in the recovery of endangered species like the Giant Panda, Tibetan Antelope and Snow Leopard. A new center for mangrove restoration is being set up in Shenzhen and the fishing ban in the Yangtze will restore that magnificent ecosystem. The Belt and Road is a great opportunity for the world to learn from good Chinese green practices.

On the evening of July 8, local time, the Israel Defense Forces issued a statement saying that Major General Avi Bluth replaced Yehuda Fox as the commander of the Israeli Central Command. Earlier that day, the Israeli army held a handover ceremony, which was presided over by the Israeli Chief of Staff Halevy. Avi Bluth joined the Israel Defense Forces in 1993 and commanded the Israeli military operations in the West Bank. In May this year, Bruce was promoted to major general and served as a military commander in the Israeli Central Command. CCTV reporters learned that in late April this year, Yehuda Fox, then commander of the Israeli Central Command, requested to resign and retire from the army in August this year. Fox had previously stated that he should bear part of the responsibility for the military intelligence failure on October 7 last year, and "must end his term like everyone else." According to the official website of the Israeli Defense Forces, the Central Command is one of the four major commands of the Israeli army, headquartered in Jerusalem, and its responsibility covers nearly one-third of Israel's territory.

The returner of the Chang'e-6 lunar probe is opened during a ceremony at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation in Beijing, capital of China, June 26, 2024. The returner of the Chang'e-6 lunar probe was opened at a ceremony in Beijing on Wednesday afternoon. During the ceremony at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, researchers opened the returner and examined key technical indicators. Photo: Xinhua As the US space industry recently faced yet more delays and stagnation with key components including manned spacecraft and space suits "going wrong," NASA has once again resorted to its "sour grapes" rhetoric upon seeing China's successful retrieval of fresh lunar soils from the far side of the moon, by claiming that China did not directly invite its scientists to participate in the lunar soil research. This behavior is a typical blame-shifting trick, Chinese experts said, noting it is clear to all that it is the US' own laws, not China, that are restricting space cooperation between the two sides. Instead of deceiving themselves by distorting the truth, the US should face up to its own problem of overall weakening engineering capability and the lack of long-term planning in its space industry. After the Chang'e-6 samples, weighing nearly 2 kilograms, were safely transported to a special laboratory for further study on Friday, NASA spokesperson Faith McKie told media that while China worked with the European Space Agency, France, Italy and Pakistan on this mission, "NASA wasn't invited to take part in the moon probe." NASA also didn't get "any direct invitation" to study China's moon rocks, after it welcomed all scientists from around the world to apply to study them, McKie told NatSec Daily. Responding to the remarks, Chinese Foreign Ministry spokesperson Mao Ning told the Global Times on Monday that China is open to having space exchanges with the US, and we also welcome countries around the world to take part in the study of lunar samples. "However, the US side seems to have forgotten to mention its domestic legislation such as the Wolf Amendment. The real question is whether US scientists and institutions are allowed by their own government to participate in cooperation with China," Mao said. "The existence of the Wolf Amendment has basically shut the door to space collaboration between the two countries," Wang Yanan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Monday. Even if research institutions of the US have the willingness to work with China on opportunities such as lunar sample research, institutions there must obtain special approval from the US Congress due to the presence of this amendment, Wang explained. Currently, no such "green light" is in sight from the Congress. Furthermore, China's collaboration with international partners is based on equality and mutual benefit, leveraging their respective scientific resources, facilities, and expertise. However, the US only wants what it doesn't have, and its engagement with China would be advantageous only to itself, Wang noted. NASA has found itself embroiled in a number of thorny issues recently, with the latest being Boeing's Starliner manned spaceship experiencing both helium leaks and thruster issues during a June 6 docking with the International Space Station (ISS), which led to an indefinite delay for its crew's return to Earth, despite NASA's insistence that they are not "stranded" in space. The return of the Starliner capsule, while has already been delayed by two weeks, will be put on hold "well into the summer" pending results of new thruster tests, which are scheduled to start Tuesday and will take approximately two weeks or even more, per NASA officials. Previously on June 24, NASA cancelled a spacewalk on the ISS following a "serious situation," when one of the spacesuits experienced coolant leak in the hatch. While being broadcast on a livestream, the astronauts reported "literally water everywhere" as they were preparing for the extravehicular activity, space.com reported. The report said that this is the second time this particular spacewalk was postponed, after a June 13 attempt with a different astronaut group was pushed back due to a "spacesuit discomfort." The recurring issues with the spacesuits are due to their much-extended service lifespan, media reported, as the puffy white ones US astronauts currently wear were designed more than 40 years ago. Despite the pressing need to replace them, NASA announced recently that it is abandoning a plan to develop next-generation spacesuits, which had been committed to be delivered by 2026, CNN reported on Thursday. One of the root causes for such problems is that the US has developed many large technology conglomerates, which for a long time have benefited significantly from government orders and industry monopolies. Consequently, in many complex engineering fields, the level of attention given is greatly insufficient, Wang noted. It also reflected the US' lack of long-term strategic planning for its manned space program. For instance, the ageing spacesuits should have been replaced a decade ago to ensure that operational suits remain in usable condition. Failure to address this issue results in a hindrance to the space station's necessary maintenance tasks and even poses life-threatening risks to astronauts in emergency situations, experts said. The issues with Boeing's spacecraft and the spacesuits are not isolated problems, but reflected a systemic issue in the US space industry - the overall weakening of engineering capabilities, they noted.

Carlsberg to buy Britvic for 1,315p per share Carlsberg will also buy out Marston's from brewing joint venture Danish brewer plans to create integrated beverage business in UK Shares in Carlsberg, Britvic, Marston's all rise July 8 (Reuters) - Carlsberg (CARLb.CO), opens new tab has agreed to buy British soft drinks maker Britvic (BVIC.L), opens new tab for 3.3 billion pounds ($4.23 billion), a move the Danish brewer said would forge a UK beverage "powerhouse" and that sent both companies' shares higher. Carlsberg clinched the takeover with a sweetened bid of 1,315 pence per share - comprising cash and a special dividend of 25 pence a share - after the British company rejected 1,250 pence per share last month. The acquisition will create value for shareholders, contribute to growth and forge a combined beer and soft drink company that is unique in the UK, CEO Jacob Aarup-Andersen told investors on a conference call. "With this transaction we are creating a UK powerhouse," he said. He brushed off concerns from some analysts about integration risks, saying Carlsberg has a strong track record of running beer and soft drink businesses in several markets. Soft drinks already make up 16% of Carlsberg's volumes. COST SAVINGS As drinkers in some markets ditch beer for spirits or cut back on drinking altogether, brewers have looked to broaden their portfolio into new categories like hard seltzer, canned cocktails and cider, as well as zero-alcohol brews. Britvic sells non-alcoholic drinks in Britain, Ireland, Brazil and other international markets such as France, the Middle East and Asia. Carlsberg said the deal will deliver a number of benefits, including cost and efficiency savings worth 100 million pounds ($128 million) over five years as it takes advantage of common procurement, production and distribution networks. It will also see Carlsberg take over Britvic's bottling agreement with PepsiCo (PEP.O), opens new tab. Carlsberg already bottles PepsiCo drinks in several markets and there is scope to add more geographies in future, Aarup-Andersen said. arlsberg halted share buy backs on Monday as a result of the deal. Chief financial officer Ulrica Fearn said these would resume once Carlsberg reaches its revised target for net debt of 2.5 times EBITDA, from 3.5 times currently - a goal it expects to meet in 2027. "Whilst this represents a shift in the strategy away from organic top- and bottom-line growth and consistent returns to shareholders, we view it as a relatively low risk transaction with attractive financials," Jefferies analysts said in a note. Carlsberg also said on Monday it will buy out UK pub group Marston's (MARS.L), opens new tab from a joint venture for 206 million pounds. That will give it full ownership of the newly formed Carlsberg Britvic after the deal.
