Rotten eggs chemical detected on Jupiter-like alien planet

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.

Australia pledges to provide more funds to Pacific island banks to counter China's influence
Australia pledged on Tuesday to increase investment in Pacific island nations, offering A$6.3 million ($4.3 million) to support their financial systems. Some Western banks are cutting ties with the region because of risk factors, while China is trying to increase its influence there. Some Western bankers have terminated long-standing banking relationships with small Pacific nations, while others are considering closing operations and restricting access to dollar-denominated bank accounts in those countries. "We know that the Pacific is the fastest-moving region in the world for correspondent banking services," Australian Treasurer Jim Chalmers said in a speech at the Pacific Banking Forum in Brisbane. "What's at stake here is the Pacific's ability to engage with the world," he said, with much of the region at risk of being cut off from the global financial system. Chalmers said Australia would provide A$6.3 million ($4.3 million) to the Pacific to develop secure digital identity infrastructure and strengthen compliance with anti-money laundering and counter-terrorist financing requirements. Experts say Western banks are de-risking to meet financial regulations, making it harder for them to do business in Pacific island nations, where compliance standards sometimes lag, undermining their financial resilience. Australia's ANZ Bank is in talks with governments about how to make its Pacific island businesses more profitable amid concerns about rising Chinese influence as financial services leave the West, Chief Executive Shayne Elliott said Tuesday. ANZ is the largest bank in the Pacific region, with operations in nine countries, though some of those businesses are not financially sustainable, Elliott said in an interview on the sidelines of the forum. "If we were there purely for commercial purposes, we would have closed it a long time ago," he said. Western countries, which have traditionally dominated the Pacific, are increasingly concerned about China's plans to expand its influence in the region after it signed several major defense, trade and financial agreements with the region. Bank of China signed an agreement with Nauru this year to explore opportunities in the country, following Australia's Bendigo Bank saying it would withdraw from the country. Mr. Chalmers said Australia was working with Nauru to ensure that banking services in the country could continue. ANZ Bank exited its retail business in Papua New Guinea in recent years, while Westpac considered selling its operations in Fiji and Papua New Guinea but decided to keep them. The Pacific lost about 80% of its correspondent banking relationships for dollar-denominated services between 2011 and 2022, Australian Assistant Treasurer Stephen Jones told the forum, which was co-hosted by Australia and the United States. “We would be very concerned if there were countries acting in the region whose primary objective was to advance their own national interests rather than the interests of Pacific island countries,” Mr. Jones said on the first day of the forum in Brisbane. He made the comment when asked about Chinese banks filling a vacuum in the Pacific. Meanwhile, Washington is stepping up efforts to support Pacific island countries in limiting Chinese influence. "We recognize the economic and strategic importance of the Pacific region, and we are committed to deepening engagement and cooperation with our allies and partners to enhance financial connectivity, investment and integration," said Brian Nelson, U.S. Treasury Undersecretary for Counterterrorism and Financial Intelligence. The United States is aware of the problem of Western banks de-risking in the Pacific region and is committed to addressing it, Nelson told the forum's participants. He said data showed that the number of correspondent banking relationships in the Pacific region has declined at twice the global average rate over the past decade, and the World Bank and the Asian Development Bank are developing plans to improve correspondent banking relationships. U.S. Treasury Secretary Janet Yellen said in a video address to the forum on Monday (July 8) that the United States is focused on supporting economic resilience in the Pacific region, including by strengthening access to correspondent banks. She said that when President Biden and Australian Prime Minister Anthony Albanese met at the White House last year, they particularly emphasized the importance of increasing economic connectivity, development and opportunities in the Pacific region, and a key to achieving that goal is to ensure that people and businesses in the region have access to the global financial system.
Samsung hit the biggest strike! Over 6,500 people attended.
More than 6,500 employees at South Korea's Samsung Electronics began a three-day mass strike on Monday (July 8), demanding an extra day of paid annual leave, higher pay raises and changes to the way performance bonuses are currently calculated. This is the largest organized strike in Samsung Electronics' more than half century of existence, and the union said that if this strike does not push employees' demands to be met, a new strike may be called. One of the core issues of the current dispute between the labor union and Samsung Electronics is raising wages and increasing the number of paid vacation days. The second demand is a pay rise. The union originally wanted a pay rise of more than 3% for its 855 employees, but last week they changed their demand to include all employees (rather than just 855). The third issue involves performance bonuses linked to Samsung's outsized profits - chip workers did not receive the bonuses last year when Samsung lost about Won15tn and, according to unions, fear they will still not get the money even if the company manages to turn around this year.
Explainer: How Boeing's Starliner can bring its astronauts back to Earth
WASHINGTON, June 24 (Reuters) - Problems with Boeing's Starliner capsule, still docked at the International Space Station (ISS), have upended the original plans for its return of its two astronauts to Earth, as last-minute fixes and tests draw out a mission crucial to the future of Boeing's (BA.N), opens new tab space division. NASA has rescheduled the planned return three times, and now has no date set for it. Since its June 5 liftoff, the capsule has had five helium leaks, five maneuvering thrusters go dead and a propellant valve fail to close completely, prompting the crew in space and mission managers in Houston to spend more time than expected pursuing fixes mid-mission. Here is an explanation of potential paths forward for Starliner and its veteran NASA astronauts, Barry "Butch" Wilmore and Sunita "Suni" Williams. THE CURRENT SITUATION Starliner can stay docked at the ISS for up to 45 days, according to comments by NASA's commercial crew manager Steve Stich to reporters. But if absolutely necessary, such as if more problems arise that mission officials cannot fix in time, it could stay docked for up to 72 days, relying on various backup systems, according to a person familiar with flight planning. Internally at NASA, Starliner's latest targeted return date is July 6, according to this source, who spoke on condition of anonymity. Such a return date would mean that the mission, originally planned for eight days, instead would last a month. Starliner's expendable propulsion system is part of the craft's "service module." The current problems center on this system, which is needed to back the capsule away from the ISS and position it to dive through Earth's atmosphere. Many of Starliner's thrusters have overheated when fired, and the leaks of helium - used to pressurize the thrusters - appear to be connected to how frequently they are used, according to Stich.
Poland and Ukraine sign bilateral security agreement
On July 8, Ukrainian President Zelensky, who was visiting Poland, and Polish Prime Minister Tusk signed a bilateral security agreement in Warsaw, the capital of Poland. The agreement clearly states that Poland will provide support to Ukraine in air defense, energy security and reconstruction. After signing the agreement, Tusk said that the agreement includes actual bilateral commitments, not "empty promises." Previously, the United States, Britain, France, Germany and other countries as well as the European Union signed similar agreements with Ukraine.
China will reach climate goal while West falls short
There has been constant low-level sniping in the West against China's record on climate change, in particular its expansion of coal mining, and its target of 2060 rather than 2050 for carbon zero. I have viewed this with mild if irritated amusement, because when it comes to results, then China, we can be sure, will deliver and most Western countries will fall short, probably well short. It is now becoming clear, however, that we will not have to wait much longer to judge their relative performances. The answer is already near at hand. We now know that in 2023 China's share of renewable energy capacity reached about 50 percent of its total energy capacity. China is on track to shatter its target of installing 1200GW of solar and wind energy capacity by 2030, five years ahead of schedule. And international experts are forecasting that China's target of reaching peak CO2 emissions by 2030 will probably be achieved ahead of schedule, perhaps even by a matter of years. Hitherto, China has advisedly spoken with a quiet voice about its climate targets, sensitive to the fact that it has become by far the world's largest CO2 emitter and aware that its own targets constituted a huge challenge. Now, however, it looks as if China's voice on global warming will carry an authority that no other nation will be able to compete with. There is another angle to this. China is by far the biggest producer of green tech, notably EVs, and renewable energy, namely solar photovoltaics and wind energy. Increasingly China will be able to export these at steadily reducing prices to the rest of the world. The process has already begun. It leaves the West with what it already sees as a tricky problem. How can it become dependent on China for the supply of these crucial elements of a carbon-free economy when it is seeking to de-risk (EU) or decouple (US) its supply chains from China? Climate change poses the greatest risk to humanity of all the issues we face today. There are growing fears that the 1.5-degree Celsius target for global warming will not be met. 2023 was the hottest year ever recorded. Few people are now unaware of the grave threat global warming poses to humanity. This requires the whole world to make common cause and accept this as our overarching priority. Alas, the EU is already talking about introducing tariffs to make Chinese EVs more expensive. And it is making the same kind of noises about Chinese solar panels. The problem is this. Whether Europe likes it or not, it needs a plentiful supply of Chinese EVs and solar panels if it is to reduce its carbon emissions at the speed that the climate crisis requires. According to the International Energy Authority, China "deployed as much solar capacity last year as the entire world did in 2022 and is expected to add nearly four times more than the EU and five times more than the US from 2023-28." The IEA adds, "two-thirds of global wind manufacturing expansion planned for 2025 will occur in China, primarily for its domestic market." In other words, willy-nilly, the West desperately needs China's green tech products. Knee-jerk protectionism demeans Europe; it is a petty and narrow-minded response to the greatest crisis humanity has ever faced. Instead of seeking to resist or obstruct Chinese green imports, it should cooperate with China and eagerly embrace its products. As a recent Financial Times editorial stated: "Beijing's green advances should be seen as positive for China, and for the world." The climate crisis is now in the process of transforming the global political debate. Hitherto it seemed relatively disconnected. That period is coming to an end. China's dramatic breakthrough in new green technologies is offering hope not just to China, but to the whole world, because China will increasingly be able to supply both the developed and developing world with the green technology needed to meet their global targets. Or, to put it another way, it looks very much as if China's economic and technological prowess will play a crucial role in the global fight against climate change. We should not be under any illusion about the kind of challenge humanity faces. We are now required to change the source of energy that powers our societies and economies. This is not new. It has happened before. But previously it was always a consequence of scientific and technological discoveries. Never before has humanity been required to make a conscious decision that, to ensure its own survival, it must adopt new sources of energy. Such an unprecedented challenge will fundamentally transform our economies, societies, cultures, technologies, and the way we live our lives. It will also change the nature of geopolitics. The latter will operate according to a different paradigm, different choices, and different priorities. The process may have barely started, but it is beginning with a vengeance. Can the world rise to the challenge, or will it prioritize petty bickering over the vision needed to save humanity? On the front line, mundane as it might sound, are EVs, wind power, and solar photovoltaics.
