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.

Recently, according to the FT, citing the latest forecast data of the market research institute SemiAnalysis, AI chip giant NVIDIA will ship more than 1 million new NVIDIA H20 acceleration chips to the Chinese market this year, and it is expected that the cost of each chip is between $12,000 and $13,000. This is expected to generate more than $12 billion in revenue for Nvidia. Affected by the United States export control policy, Nvidia's advanced AI chip exports to China have been restricted, H20 is Nvidia based on H100 specifically for the Chinese market to launch the three "castration version" GPU among the strongest performance, but its AI performance is only less than 15% of H100, some performance is even less than the domestic Ascend 910B. When Nvidia launched the new H20 in the spring of this year, there were reports that due to the large castration of H20 performance, coupled with the high price, Chinese customers' interest in buying is insufficient, and they will turn more to choose China's domestic AI chips. Then there are rumors that Nvidia has lowered the price of the H20 in order to improve its competitiveness. However, the latest news shows that due to supply issues caused by the low yield of the Ascend 910B chip, Chinese manufacturers in the absence of supply and other better options, Nvidia H20 has started to attract new purchases from Chinese tech giants such as Baidu, Alibaba, Tencent and Bytedance. Analysts at both Morgan Stanley and SemiAnalysis said the H20 chip is now being shipped in bulk and is popular with Chinese customers, despite its performance degradation compared to chips Nvidia sells in the United States.

A children's hospital in the Ukrainian capital was hit by a Russian missile on Monday as part of a wave of airstrikes across Ukraine that has killed at least 31 people and injured 154 others. "Russian terrorists have once again launched a massive missile attack on Ukrainian cities - Kiev, Dnipro, Kryvyi Rih, Slaviansk, Kramatorsk," said Ukrainian President Volodymyr Zelenskyy. Zelensky said Russia fired more than 40 missiles of different types at the five cities in daytime attacks, hitting residential buildings and public infrastructure. The Ukrainian air force said it intercepted 30 missiles. Authorities said the attack on Kiev killed seven people, while the attack on Kryvyi Rih, Zelensky's birthplace in central Ukraine, killed 10 and injured 47. United Nations Secretary-General António Guterres condemned the attacks, calling the assault on the Kiev hospital and another medical facility in the capital's Dniprovsky district "particularly egregious," said his spokesman, Stephane Dujarric. "Direct attacks on civilians and civilian objects are prohibited under international humanitarian law. Any such attacks are unacceptable and must cease immediately," Dujarric said. The U.N. Security Council will meet Tuesday to discuss the Russian strikes, diplomats said. The Russian Defense Ministry said the strikes targeted Ukrainian defense factories and a military aviation base and were successful. It denied striking any civilian facilities and claimed, without evidence, that photos from Kiev showed the damage was caused by a Ukrainian anti-aircraft missile. Ukrainian Air Force Colonel Yurii Ignat said Russia has been improving the effectiveness of its air strikes by equipping its missiles with enhanced features, including so-called heat decoys that can throw air defense systems off target. In comments sent to The Associated Press, he said the cruise missiles flew low in Monday's attack -- just 50 meters off the ground -- making them harder to hit. Western countries, led by the United States, have provided Ukraine with billions of dollars in arms support. They will hold a three-day NATO summit in Washington starting Tuesday to work out how to reassure Kiev of NATO's strong support and give Ukrainians hope that their country can survive the largest conflict in Europe since World War II. "Today's Russian missile strike that killed dozens of Ukrainian civilians and caused damage and loss of life to Kyiv's largest children's hospital is a horrifying reminder of Russia's brutality," U.S. President Joe Biden said in a statement Monday. "It is critical that the world continues to stand with Ukraine at this important moment and that we do not ignore Russian aggression." Biden said in the statement that he will meet with President Zelensky during the NATO summit in Washington this week "to make clear our unwavering support for Ukraine." Biden continued: "We will join our allies in announcing new measures to strengthen Ukraine's air defenses and help protect their cities and civilians from Russian attacks. The United States stands with the Ukrainian people." Czech President Petr Pavel said the hospital attack was "inexcusable" and he hoped the NATO summit would reach a consensus that Russia is "the greatest threat and we must be fully prepared to deal with it." Zelensky said during a visit to Poland that he hoped the NATO summit would provide Ukraine with more air defense systems. The Ukrainian leader said rescuers were digging through the rubble of the Ohmatdit Children's Hospital in Kyiv and that the number of casualties was not yet known. Kyiv Mayor Vitali Klitschko said at least 16 people were injured, including seven children, and the attack caused a two-story wing of the hospital to partially collapse. Doors and windows were blown off the hospital's 10-story main building, and the walls were charred. The floor of one room was splattered with blood. Hospital officials said the intensive care unit, operating room and oncology department were damaged.

Beijing self-driving cars on the road will usher in legislative protection. Recently, the Beijing Municipal Bureau of Economy and Information Technology solicited comments on the "Beijing Autonomous Vehicle Regulations (Draft for Comment)". The city intends to support the use of autonomous vehicles for urban public electric bus passenger transport, online car booking, car rental and other urban travel services. In addition to application scenarios, the draft for comments also standardizes autonomous driving innovation from many aspects, such as whether there is a driver, how to deal with traffic problems, and so on. The release of the opinion draft also means that the commercialization of automatic driving is accelerating, and perhaps soon we will be able to experience the convenience of automatic driving. In addition, the accelerated pace of autonomous driving, and whether it will have an impact on the taxi and traditional network car industry, it is also worth thinking about.

Japan and the Philippines signed an important defense agreement, and the two sides became "quasi-allies". On July 8, local time, Japan and the Philippines signed the "Reciprocal Access Agreement" in Manila. The agreement will relax restrictions on the movement of personnel between the Japanese Self-Defense Forces and the Philippine military during joint exercises, mutual visits and other operations in each other's countries. In response, Chinese Foreign Ministry spokesman Lin Jian responded at a regular press conference on the 8th that exchanges and cooperation between countries should not undermine mutual understanding and trust between regional countries, should not undermine regional peace and stability, and should not target third parties or undermine the interests of third parties. The Asia-Pacific region does not need military groups, let alone "small circles" that provoke camp confrontation and instigate a "new Cold War". Any actions that undermine peace and stability in the region and undermine unity and cooperation in the region will arouse the vigilance and common opposition of the people in the region. Japan and the Philippines upgraded to a "quasi-alliance" relationship On the same day, a "2+2" meeting attended by the foreign ministers and defense ministers of Japan and the Philippines was held in Manila. Japanese Defense Minister Minoru Kihara and Foreign Minister Yoko Kamikawa attended the talks with Philippine Defense Minister Gilbert Teodoro and Foreign Minister Enrique Manalo. This is the second Japan-Philippines "2+2" meeting. The last one was held in Tokyo in April 2022. Witnessed by Philippine President Marcos, the two sides signed the "Reciprocal Access Agreement". Marcos expressed the hope that the bilateral relations between the Philippines and Japan and the trilateral cooperation between the Philippines, Japan and the United States will be further deepened. The "Reciprocal Access Agreement" is also known as the "Military Visits Agreement". Military and defense cooperation between sovereign states, especially sending troops into each other's territory, usually faces complicated procedures and other problems. In order to simplify the procedures, the two countries will reach relevant agreements to simplify the approval procedures for the entry of troops from both sides into each other's countries, and facilitate mutual visits and joint military activities between the two countries' troops. The "Reciprocal Access Agreement" was born. Take the "Reciprocal Access Agreement" signed by Japan and Australia (full name "Agreement between Japan and Australia on Promoting Mutual Access and Cooperation Facilitation between the Japanese Self-Defense Forces and the Australian Defense Force") as an example. The agreement has 29 articles, covering many areas such as entry and exit procedures for troops, jurisdiction, taxation, cost burden and compensation. The key is to simplify the entry and exit procedures for visiting troops and their members, ships, aircraft, etc., relax restrictions on the transportation of weapons, ammunition and materials carried by visiting troops, and provide a legal basis for the two countries' troops and weapons and equipment to enter each other's territory. Japan and the Philippines signed the "Reciprocal Access Agreement", making the Philippines the third country to conclude this agreement with Japan after Australia and the United Kingdom. Cai Liang, Secretary-General and Researcher of the China-Japan Relations Research Center of the Shanghai Institute for International Studies, analyzed to The Paper (www.thepaper.cn) that Japan and the Philippines have their own strategic considerations for signing the "Reciprocal Access Agreement". As for the Philippines, due to its limited strength, it does not exclude any foreign power willing to strengthen military cooperation with the Philippines from intervening in the South China Sea situation. Therefore, it can be seen that in the past two years, the Philippines has actively promoted Australia, France, India and other countries to intervene in the South China Sea and strengthen military cooperation with them, involving intelligence, weapons and equipment, and training and exercises. "Japan's purpose is very simple. Strengthening military cooperation with the Philippines is to strategically balance China. The United States and the Philippines are allies, and the US-Japan alliance has been upgraded to a 'quasi-alliance'. The military cooperation between the United States, Japan and the Philippines has been upgraded to a new level." Cai Liang said, "The signing of an important defense agreement between Japan and the Philippines will make it easier for Japan to intervene in the South China Sea situation and seek the 'three seas linkage' of the East China Sea, the South China Sea, and the Taiwan Strait, in order to better respond to China's strategy and enhance its international influence." As for whether the signing of the "Reciprocal Access Agreement" means that Japan will deploy the Self-Defense Forces in the Philippines, Cai Liang pointed out that this agreement only simplifies the procedures for the troops of both sides to enter each other's territory, and is more suitable for short-term training, military exercises, etc., and is not a long-term deployment of the Self-Defense Forces in the Philippines. The two countries deepen military cooperation The Philippine presidential office also said in a statement that Japan is one of the four major strategic partners of the Philippines, and the two countries have established a strategic partnership for more than ten years. It seems no coincidence that Japan and the Philippines signed the "Reciprocal Access Agreement" at this time. Recently, China-Philippines relations have become tense around the situation in the South China Sea. The Global Times quoted Japan's Kyodo News Agency as saying that the two sides are seeking to strengthen cooperation against China. Minoru Kihara said last week: "The Philippines is located in a strategically important region, occupies a key position on Japan's sea lanes, and is also an ally of the United States. Joint training and strengthening cooperation with the Philippines are of great significance to the realization of a 'free and open Indo-Pacific region'." Cai Liang said that Japan's intervention in the South China Sea situation is mainly to reduce strategic pressure in the East China Sea and southwest of Japan, but it is not conducive to peace and stability in the South China Sea. It is reported that Japan and the Philippines began negotiations on the agreement in November last year. The signing of the "Reciprocal Access Agreement" by the two sides lays the foundation for the two countries to strengthen bilateral and even multilateral military cooperation in the future. The Japanese government intends to allow the Self-Defense Forces to formally participate in the annual US-Philippines "Shoulder to Shoulder" joint exercises around the Philippines after the agreement comes into effect. The Self-Defense Forces previously participated in the "Shoulder to Shoulder" exercises as observers, and will be able to formally participate after signing the agreement. In April this year, the United States and the Philippines held the largest "Shoulder to Shoulder" exercise to date, involving 5,000 Philippine personnel and 11,000 US personnel. The military exercise also included about 150 Australian military personnel and 100 French naval personnel. According to the plan, 14 countries including Japan and India sent personnel as observers. The "Typhon" medium-range missile launch system deployed by the US military on Luzon Island in the Philippines for the first time participated in the exercise, which aroused great attention from all walks of life. In terms of weapons and equipment exports, Japan and the Philippines have gradually strengthened military cooperation in recent years. The Philippines recently agreed to purchase five Coast Guard patrol ships from Japan to enhance its patrol capabilities in the South China Sea. Defense News reported in November last year that the Philippines had received an early warning radar system from Japan in 2023, the first major equipment transfer since the Japanese government lifted the postwar defense export ban in 2014. The Japanese Ministry of Foreign Affairs stated that Kamikawa mentioned topics such as defense equipment transfer, "government security capability enhancement support" (OSA), and economic and trade cooperation. The OSA project was created by the Kishida government and plans to allocate billions of yen in budget to assist the military construction of the Philippines and other countries, including providing the Philippines with 5 sets of coastal surveillance radars. Regarding Japan's relaxation of restrictions on defense equipment exports, the Chinese Ministry of Defense previously responded that Japan has continuously broken through the constraints of the "peace constitution" and the principle of "exclusive defense", and has been making small moves in the field of military security, which has aroused high vigilance and strong concern from the international community. China requires Japan to deeply reflect on its history of aggression, attach importance to the security concerns of its Asian neighbors, adhere to the path of peaceful development, and win the trust of its Asian neighbors and the international community with practical actions.
