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.

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.

TikTok to introduce a new feature that can clone your voice with AI in just 10 second
Use of AI is certainly the hottest topic in the tech industry and every major and minor player in this industry is using AI in some way. Tools like ChatGPT can help you do a wide range of task and even help you generate images. The other thing is - Voice Cloning. OpenAI recently introduced a voice engine that can generate clone of your voice with just 15 seconds of your audio. There is no shortage of voice cloning tools on the web which can help you do the same. The newest tech giant which is going to use AI to clone your voice is - TikTok. We all know TikTok, posting short videos with filters, effects and all other kind of things. So TikTok found a way to use the voice cloning AI in its app. TikTok is working on this feature, which does not seem to really have a proper name, it just references it as "Create your voice with AI" and "TikTok Voice Library". In the latest version of TikTok I came across some strings which indicates that TikTok is working on it. I was also able to access the initial UI which introduces the feature and was able to see the terms and condition of "TikTok Voice Library" which user have to accept in order to use the feature. Here are the screenshots from the app- As you can in the screenshot above, this is the initial screen which a user will see for the first time they access this feature. Tiktok claims that it can create an AI verison of your voice in just 10 seconds. The generated AI voice clone can be used with text-to-speech in TikTok videos. It also outline the process of how it will work. You have to record yourself speaking and TikTok will process the voice and use information about your voice to generate your AI voice. When it comes to privacy, your AI voice will stay private and you can delete it anytime. Tapping the "Continue" button brings "TikTok Voice Library Terms" screen which a user should definitely read, you can see here and read as well - How it will work After agreeing to terms and conditions I was introduced with a screen where TikTok will show some text and user have to press the record button while reading the text. Now unfortunately I did not see any text. This is probably because the feature is not fully ready or the backend from which it fetches the text is not live yet. Manually pressing the record button and saying random things also shows an error. So, it's also not possible to provide any sample voice generated with it and see how it compares to other voice cloning competitors. If it starts working someday, it will process your recorded voice and generate AI version of your voice. Here is a screenshot of that screen - My guess is that whenever the feature starts working, users have to clone voice only one time and the saved AI voice can be used through the text-to-speech method to add voice in your videos. You just have to type the words, choice is yours :p
Morning Bid: Eyes switch to inflation vs elections, Powell up
A look at the day ahead in U.S. and global markets from Mike Dolan After an intense month focused on election risk around the world, markets quickly switched back to the more prosaic matter of the cost of money - and whether disinflation is resuming to the extent it allows borrowing costs to finally fall. Thursday's U.S. consumer price update for June is the key moment of the week for many investors - with the headline rate expected to have fallen two tenths of a percentage point to 3.1% but with 'core' rates still stuck at 3.4%. With Federal Reserve chair Jerome Powell starting his two-pronged semi-annual congressional testimony later on Tuesday, the consensus CPI forecast probably reflects what the central bank thinks of the situation right now - encouraging but not there yet. But as the U.S. unemployment rate is now back above 4.0% for the first time since late 2021, markets may look for a more nuanced approach from the Fed chair that sees it increasingly wary of a sudden weakening of the labor market as real time quarterly GDP estimates ebb again to about 1.5%. There were some other reasons for Fed optimism in the lead up to the testimony. The path U.S. inflation is expected to follow over coming years generally softened in June, amid retreating projections of price increases for a wide array of consumer goods and services, a New York Fed survey showed on Monday. Inflation a year from now was seen at 3% as of June - down from the expected rise of 3.2% in May - and five-year expectations fell to 2.8% from 3%. Crude oil prices are better behaved this week, too, falling more than 3% from the 10-week highs hit late last week and halving the annual oil price gain to 10%. The losses on Tuesday came after a hurricane that hit a key U.S. oil-producing hub in Texas caused less damage than many in markets had expected - easing concerns over supply disruption. Before Powell starts speaking later, there will also be an update on U.S. small business confidence for last month.
NASA plays 'blame-shifting' game with China as lunar soil research set to start
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.
