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.

July 9 (Reuters) - The National Highway Traffic Safety Administration (NHTSA) has opened a recall query into 94,275 Stellantis-owned (STLAM.MI), opens new tab Jeep SUVs over a loss of motive power, the U.S. auto safety regulator said on Tuesday. The investigation targets Jeep's Wrangler 4xe hybrid SUVs manufactured between 2021 through 2024. Chrysler had previously recalled, opens new tab the same model in 2022 to address concerns related to an engine shutdown. A recall query is an investigation opened by safety regulators when a remedy to solve an issue appears inadequate. The complaints noted in the new report include both failures in vehicles that received the recall remedy and those not covered by the prior recall, the NHTSA said.

JOHANNESBURG, July 9 (Reuters) - The South African rand was little changed in early trade on Tuesday, as markets awaited the Federal Reserve chair's testimony in Washington and U.S. June inflation data for clues on the country's future interest rate path. At 0644 GMT, the rand traded at 18.1300 against the dollar , near its previous close of 18.1175. "The rand has opened marginally softer at 18.13 this morning, and we expect trading to remain range-bound in the short term," said Andre Cilliers, currency strategist at TreasuryONE. Markets will listen to the tone of Fed Chair Jerome Powell's testimony in Washington on Tuesday and Wednesday and look to June inflation data out of the U.S. later this week for hints on the future interest rate path in the world's biggest economy. "Analysts will be gauging the Fed's response to the recent softer U.S. economic and labour data, with markets already starting to price in two rate cuts this year," Cilliers added. The risk-sensitive rand often takes cues from global drivers like U.S. economic policy in the absence of major local factors. South Africa's benchmark 2030 government bond was slightly stronger in early deals, with the yield down 1 basis point at 9.74%.

The U.S. Navy's Pacific Fleet announced on Wednesday (May 22) that the 2024 Rim of the Pacific Exercise (RIMPAC 2024) is expected to take place on June 26, with 29 countries participating in and around the Hawaiian Islands, a larger lineup than the previous exercise in 2022. The Philippines, which has had multiple maritime conflicts with China recently, and Japan, which has tense diplomatic relations with China, will send troops to participate. China has been excluded from participating in the international military exercise since 2018, and its aggressive actions and reactions are causing tensions in the Pacific region to continue to rise. The biennial Rim of the Pacific military exercise is the world's largest international maritime exercise. The U.S. Navy said that the exercise will last until August 2, and it is expected to involve 29 countries, 40 surface ships, 3 submarines, 14 countries' army forces, more than 150 aircraft and more than 25,000 personnel. The U.S. Navy said that the theme of the 29th RIMPAC 2024 is "Partners: Integrated and Ready", emphasizing inclusiveness as the core, promoting multinational cooperation and trust, and using military interoperability to achieve their respective national goals to strengthen integrated and ready alliance partners. Its goal is to "enhance collective strength and promote a free and open Indo-Pacific region" through joint training and operations. The 29 countries participating in the exercise this year include Australia, Belgium, Brazil, Brunei, Canada, Chile, Colombia, Denmark, Ecuador, France, Germany, India, Indonesia, Israel, Italy, Japan, Malaysia, Mexico, the Netherlands, New Zealand, Peru, South Korea, the Philippines, Singapore, Sri Lanka, Thailand, Tonga, the United Kingdom and the United States. Compared with the 28th RIMPAC held in 2022, which involved 26 countries, 38 surface ships, 4 submarines, 9 countries' army forces, more than 170 aircraft, and about 25,000 officers and soldiers, the number of countries, ships and army forces participating in this exercise has increased. The countries participating in this year's RIMPAC military exercise include all members of the Quadrilateral Security Dialogue (QUAD) between the United States, Japan, India and Australia, and the Australia-UK-US Trilateral Security Partnership (AUKUS), as in the previous exercise. In addition, countries surrounding the South China Sea and the South Pacific island nation of Tonga are also participating. Many analysts believe that the military exercise itself is sending a message to China: China's expansion in the Western Pacific region will be blocked and defeated. The United States invited China to participate in the RIMPAC military exercise twice in 2014 and 2016. In 2018, due to China's expansion in the South China Sea, the United States withdrew its invitation to China. In addition, despite Taiwan's repeated willingness to participate, Taiwan is still not included in the 29 countries participating in this year's RIMPAC military exercise. Analysts pointed out that the US-led RIMPAC military exercise is intended to unite allies to militarily intimidate China. If Taiwan is invited to join, it will be too provocative to China, which will not only aggravate the tension between the United States and China, but also embarrass some allies. The U.S. Navy said the commander of the U.S. Third Fleet will serve as the commander of the joint task force for the exercise, while Chilean Navy Commodore Alberto Guerrero will serve as deputy commander of the joint task force, which is a first in the history of the RIMPAC military exercise. In addition, Japan Maritime Self-Defense Force Rear Admiral Kazushi Yokota will also serve as deputy commander. Other key leaders of the multinational force exercise include Canadian Commodore Kristjan Monaghan, who will command the maritime forces, and Australian Air Force Commodore Louise Desjardins, who will command the air forces. According to the U.S. Stars and Stripes, Vice Admiral Michael Boyle is currently the commander of the U.S. Third Fleet. Vice Admiral John Wade has been nominated to replace Boyle. The U.S. Navy press release said the exercise will enhance the ability of international joint forces to "deter and defeat aggression by major powers in all domains and conflict levels," but did not provide specific information on which exercises will be held this summer. Previous RIMPAC training exercises have included sinking ships at sea with missiles, amphibious landings and the first landing of a Marine Corps Osprey aircraft on an Australian ship.

July 4 (Reuters) - A hacker gained access to the internal messaging systems at OpenAI last year and stole details about the design of the company's artificial intelligence technologies, the New York Times reported, opens new tab on Thursday. The hacker lifted details from discussions in an online forum where employees talked about OpenAI's latest technologies, the report said, citing two people familiar with the incident. However, they did not get into the systems where OpenAI, the firm behind chatbot sensation ChatGPT, houses and builds its AI, the report added. OpenAI executives informed both employees at an all-hands meeting in April last year and the company's board about the breach, according to the report, but executives decided not to share the news publicly as no information about customers or partners had been stolen. OpenAI executives did not consider the incident a national security threat, believing the hacker was a private individual with no known ties to a foreign government, the report said. The San Francisco-based company did not inform the federal law enforcement agencies about the breach, it added. OpenAI in May said it had disrupted five covert influence operations that sought to use its AI models for "deceptive activity" across the internet, the latest to stir safety concerns about the potential misuse of the technology. The Biden administration was poised to open up a new front in its effort to safeguard the U.S. AI technology from China and Russia with preliminary plans to place guardrails around the most advanced AI Models including ChatGPT, Reuters earlier reported, citing sources.
