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.
"Pictures on the wall were falling," New Yorkers rattled by earthquake
An earthquake jolted New York City on Friday morning, followed by more than 10 aftershocks which shook New Jersey, sending tremors as far as Philadelphia to Boston and jolting buildings in Manhattan and throughout its five boroughs. The preliminary quake, measuring 4.8 magnitude, centered around Lebanon, New Jersey, approximately 60 kilometers from New York City, with a depth of about 5 kilometers. Following the earthquake, New York City mayor Eric Adams stated at a press conference that no injuries had been reported, but they would continue to monitor and inspect critical infrastructure. The densely populated New York City was caught off guard by the unusual event. Broadcaster CBS reported that New York had not experienced an earthquake of this magnitude since 1884. Residents in Brooklyn expressed their shock when experiencing tremors which shook the city. "At first, I thought it was just construction next door, but then I noticed the pictures on the wall had fallen," Jennifer Wu, a resident in New York, told the Global Times on Saturday. Video footage circulating online showed the Statue of Liberty and the New York City skyline trembling as the earthquake struck. An angle from directly above Lady Liberty caught Ellis Island shaking during the incident. "It is fine," New York's famous Empire State Building posted on social platform X after the earthquake. The United Nations headquarters located in New York was hosting a Security Council meeting on the Israeli-Palestinian issue, and diplomats present in the meeting felt the tremors, local media reported. According to the Weather Channel, residents in Baltimore, Philadelphia, New Jersey, Connecticut, Boston and other areas of the Northeast seaboard also reported shaking. Tremors lasting for several seconds were felt over 200 miles away near the Massachusetts-New Hampshire border. The New York mayor told the press that New Yorkers should go about their normal day, while the governor Kathy Hochul emphasized the seriousness of the situation. She initiated assessments for damage across the state and had discussions with New Jersey Governor Phil Murphy. The quake caused flight delays throughout the New York area, with temporary control measures put in place across New York's John F. Kennedy International Airport, Newark Liberty International Airport in Newark, New Jersey, and Baltimore-Washington's Thurgood Marshall International Airport, checking for damage to runways. Operations resumed around Friday noon, ABC reported.
Koenigsegg Fused Three Hypercars Into One To Make The Chimera
Koenigsegg Agera RS Chimera combines technologies from Agera RS, CC850, and Jesko. An Agera RS platform features the engine from the Jesko and the simulated manual gearbox from the CC850. Development took three years, thanks to software and hardware integration challenges. A "chimera," for the uninitiated, is described as a mythical creature whose anatomy comes from multiple animals, creating a hybrid of two or more creatures' best bits. It's also the name of the latest one-off creation from Koenigsegg, and it's certainly apt; the Koenigsegg Agera RS Chimera is an amalgam of technologies from the decade-old, record-breaking Agera RS, the fascinatingly innovative CC850, and the awe-inspiring Jesko - which just recently set four new acceleration records. There's also a hint of Regera in here, which had some impressive records of its own. As reported by Mr. JWW, the strictly one-off special edition was commissioned by FIA President Mohammed Ben Sulayem, and both he and one of Koenigsegg's engineers arrived at the same name. Let's take a closer look and see exactly why this is a hybrid, even though it's not electrified. Three Cars In One The Chimera was originally a regular Agera RS and one of several Koenigsegg megacars owned by Ben Sulayem, but he asked Christian and the team to initiate a special project on his behalf. Around the same time, the extraordinary Koenigsegg CC850 was revealed at Monterey Car Week 2022, introducing the innovative Engage Shift System (ESS). This was based on the already astonishingly fast nine-speed Light Speed Transmission, with new actuators and sensors added to enable the simulation of a manual transmission without a physical link between the shifter and the gearbox. Like the rest of the world, the FIA boss was enamored by this novel technology, and as a wealthy 'Egg collector, he asked for it to be put into his special Agera-based project. Christian pondered this and ultimately decided to fulfill the request, in the process turning Ben Sulayem's special edition into something of a development mule for the ESS. But unlike the CC850, the Chimera got the larger turbos of the Jesko, enabling around 1,280 horsepower on regular gas and up to 1,600 hp on E85. That means this is an Agera RS with a CC850 transmission and a Jesko engine. On paper, that sounds simple, but the reality was anything but... Three Shifting Experiences Took Three Years To Combine According to a video from YouTuber and Koenigsegg distributor Mr. JWW, this development process took three years and required the relocation of the battery, new mounts for the powertrain, new harnesses, new software and controllers, and even a new infotainment system. To ensure all the electronics worked seamlessly was a challenge, but then Ben Sulayem asked for another layer of intricacy, requesting that paddle shifters be added, like in the Jesko Absolut and Jesko Attack. In the CC850, you could only switch between the simulated manual mode and fully automatic shifts, but now, the Chimera's development has unlocked manually operable paddles, which have now been added as the only option you can add to a CC850. There was also significant relocation and redesigning of suspension components, with parts from the Jesko and the Regera forming the subframe and elements of the suspension, respectively. A new scoop for the new transmission's cooler was also added, but it looks like it was always planned. Christian von Koenigsegg says this is a true one-off, saying that it would be cheaper and easier to start something all-new from scratch than to mix new and old technologies again, and that it's simply "too much work" to tackle a retrofit project. The Chimera is not completed just yet, as there are still subtle elements to refine, such as the bite point of the clutch pedal, but these minor issues will surely be resolved soon. It's an amazing feat, combining three hypercars in one, and we can't even fathom how Koenigsegg will top this in the future, but we don't doubt that Christian and his team will continue to do just that.

Avi Bruce appointed as head of IDF Central Command
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.
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.
