NASA scientists were surprised to discover a high-speed jet stream near Jupiter's equator. Previous telescopes couldn't see Jupiter's atmosphere in such detail so they missed the fierce winds. AdvertisementAdvertisementNASA's James Webb Space Telescope has helped scientists discover that Jupiter has a thin jetstream whipping around the planet at 320 miles per hour — twice as fast as Earth's strongest hurricanes. The JWST's predecessor, Hubble, was not strong enough to clearly capture images of the hazier parts of Jupiter's atmosphere, NASA said in a press release detailing its findings. The JWST was only able to detect the jet stream when it looked at a particular band of infrared light, which revealed changes in atmospheric features at varying altitudes.

CNN —Too often seaweed is portrayed as a slimy, smelly nuisance that disrupts beach trips and ocean swims. In fact, seaweed, officially a type of marine algae, is an untapped resource that could transform the planet and our health. Farmer Jean-Marie Pedron picks edible seaweed along a beach of Le Croisic in western France in March 2021, for a three-starred chef. As well as offering hope for the future, seaweed indelibly shaped our past, as a fascinating finding released this week has revealed.

CNN —Astronomers using the James Webb Space Telescope have for the first time detected tiny quartz crystals containing silica — a common mineral on Earth — within the atmosphere of a blazing hot exoplanet. An artist's concept depicts what the exoplanet WASP-17b could look like. What the quartz crystals reveal about WASP-17bWasp-17b takes 3.7 Earth days to complete one orbit around its star. Webb detected quartz crystals in the atmosphere of WASP-17b. While the clouds can drift around the planet, they likely vaporize on the hot day side, which could send the quartz particles swirling.

Scientists had previously thought Luminous Fast Blue Optical Transients were caused by dying stars. AdvertisementAdvertisementA bright flash of blue light appearing in the middle of seemingly empty space has scientists confused. Scientists previously thought they knew what could cause such a bright burst of energy. That's much too far for a core-collapse supernova to travel. There are a few more hypotheses for what could cause the bright blue flashes.

And for scientists, preserved footprints can lead to unexpected journeys into the past that rewrite history. National Park ServiceWhen the discovery of 61 fossilized human footprints found in New Mexico’s White Sands National Park was first announced in 2021, the ancient find changed the timeline of early humans living in the Americas. That’s why the footprints represent such a crucial missing chapter in human history. Across the universePlanetlike objects were spotted in a new image of the Orion Nebula taken by the James Webb Space Telescope.

Star formation in the early galaxies occurred in occasional big bursts, they found, rather than at a steady pace. "According to the standard model of cosmology, there should not be many very massive galaxies during cosmic dawn because it takes time for galaxies to grow after the Big Bang. And the reason this is so significant is that we explain these very bright galaxies without having to break the standard cosmological model," Faucher-Giguère added. They blast gas into space that becomes ingredients for another burst of star formation. But the stronger gravitational effects in larger galaxies prevent these bursts, favoring steady star formation.

CNN —New images from the James Webb Space Telescope have revealed surprising pairs of planet-like objects in the Orion Nebula that have never been detected before. The Orion Nebula, a glowing cloud of dust and gas, is one of the brightest nebulae in the night sky and identifiable as the sword in the Orion constellation. But no existing theories explain how the JuMBOs formed, or why they’re present in the Orion Nebula, McCaughrean said. This Webb image shows the full survey of the inner Orion Nebula and Trapezium Cluster, captured in long wavelengths of light. Meanwhile, other research focused on different star-forming regions could reveal whether JuMBOs are elsewhere beyond the Orion Nebula.

Workers using OpenAI's ChatGPT may actually perform more poorly than those who don't, new BCG research finds. AdvertisementAdvertisementIf you're using ChatGPT as a shortcut at work, you may want to be extra careful. For tasks "inside the frontier," consultants using AI were "significantly more productive" and "produced significantly higher quality results" than those who weren't using the chatbot. BCG's findings demonstrate a cautionary tale for workers thinking about using ChatGPT to help do their jobs. AI-generated errors may only get worse: In a recent paper, AI researchers found that generative AI models could soon be trained on AI-generated content — a phenomenon they call "model collapse."

CNN —A building block of life may exist inside the global ocean on Europa, one of Jupiter’s icy moons. Scientists have long questioned whether Europa’s ocean contained carbon and other chemicals necessary for life. Astronomers used the Webb telescope to observe Jupiter's icy moon Europa. Carbon dioxide appears to be concentrated in a region of “chaos terrain” on Europa called Tara Regio. Future observations of Europa with the Webb Telescope could help astronomers determine whether there are other concentrated regions of carbon dioxide on the surface, Trumbo said.

CNN —I once felt the immense force unleashed by an earthquake in 1999 when I was living in Taipei, Taiwan. It was a feeling I was reminded of again this week when writing about a mysterious seismic phenomenon witnessed during Morocco’s recent devastating earthquake. Force of natureReports of multicolor “earthquake lights,” such as the ones seen in videos captured before Morocco’s 6.8 magnitude quake on September 8, go back centuries to ancient Greece. Researchers are beginning to understand the different forms the lights take and where they might appear. One 2014 study found the mystery lights could result from certain rocks when put under stress, but there is still no consensus on exactly what causes these outbursts.

NASA's James Webb Space Telescope discovered signs of a vast ocean on the planet K2-18 b. Astronomers can't directly look at the surface of the planet, called K2-18 b, but Webb analyzed its atmosphere for hints of what may lie below. That's a strong mark against the molecule's existence on K2-18 b. Confirming these findings requires a lot more observation of K2-18 b. As Blain put it: "K2-18 b is not exactly an Earth twin."

Google CEO Sundar Pichai isn't in a rush to catch up to OpenAI, he told Wired. Releasing Google's AI products before ChatGPT was launched "wouldn't have worked out as well," he said. Pichai's thoughts on AI come months after the CEO declared a "code red" for Google's search engine. "In some ways, it was an exciting moment for me, because we are building that underlying technology and deploying it across our products," Pichai told Wired in an interview published on Monday. Since the disastrous demo, Google has announced a slate of new AI products.

The Webb telescope, which can detect infrared light invisible to the human eye, searched for exactly what elements are featured in the planet’s atmosphere. On Earth, dimethyl sulfide “is only produced by life,” according to NASA. Hot ocean worldsThe discoveries about its atmospheric composition suggest it could be a “Hycean exoplanet,” a theoretical type of exoplanet that runs hot but is covered in oceans and has a hydrogen-rich atmosphere. There are no confirmed Hycean exoplanets just yet. “This means our work here is but an early demonstration of what Webb can observe in habitable-zone exoplanets.”

Opinion: The Deep Space Network is in trouble
  + stars: | 2023-09-11 | by ( Opinion Don Lincoln | ) edition.cnn.com   time to read: +6 min
The Deep Space Network, or DSN, is an interconnected set of three radio telescope facilities spread across the globe. Indeed, without the DSN, NASA’s robotic exploration of deep space would simply not be possible. On the contrary, if humanity is going to once again venture into deep space, it will be crucial to be able to maintain a radio link with those intrepid explorers. Both of those missions, indeed all deep space programs, depend on reliable communication, or they will fail. The Deep Space Network is NASA’s link to the planets, and it needs additional support if we ever hope to boldly go where no one has gone before.

But as more people turn to this buzzy technology for things like homework help, workplace research, or health inquiries, one of its biggest pitfalls is becoming increasingly apparent: AI models often just make things up. Researchers have come to refer to this tendency of AI models to spew inaccurate information as “hallucinations,” or even “confabulations,” as Meta’s AI chief said in a tweet. A number of high-profile hallucinations from AI tools have already made headlines. Cracking down on AI hallucinations, however, could limit AI tools’ ability to help people with more creative endeavors — like users that are asking ChatGPT to write poetry or song lyrics. How to prevent or fix AI hallucinations is a “point of active research,” Venkatasubramanian said, but at present is very complicated.

CNN —The James Webb Space Telescope has revealed colorful new portraits of the iconic Ring Nebula. Webb previously captured a different perspective on the Ring Nebula, as well as the similar-looking Southern Ring Nebula. A longtime favorite of astronomers, the Ring Nebula has been studied for years due to its observability and the insight it can provide into the lifetime of stars. Messier and astronomer Darquier de Pellepoix discovered the Ring Nebula in 1779. As the dying star was throwing off its atmosphere, the companion star shaped the outflow and sculpted it.”
