NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA’s James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars.
“A big question in the Central Molecular Zone of our galaxy has been, if there is so much dense gas and cosmic dust here, and we know that stars form in such clouds, why are so few stars born here?” said astrophysicist John Bally of the University of Colorado Boulder, one of the principal investigators. “Now, for the first time, we are seeing directly that strong magnetic fields may play an important role in suppressing star formation, even at small scales.”
Detailed study of stars in this crowded, dusty region has been limited, but Webb’s advanced near-infrared instruments have allowed astronomers to see through the clouds to study young stars like never before.
“The extreme environment of the galactic center is a fascinating place to put star formation theories to the test, and the infrared capabilities of NASA’s James Webb Space Telescope provide the opportunity to build on past important observations from ground-based telescopes like ALMA and MeerKAT,” said Samuel Crowe, another principal investigator on the research, a senior undergraduate at the University of Virginia and a 2025 Rhodes Scholar.
Bally and Crowe each led a paper published in The Astrophysical Journal.
Image A: Milky Way Center (MeerKAT and Webb)
An image of the Milky Way captured by the MeerKAT (formerly the Karoo Array Telescope) radio telescope array puts the James Webb Space Telescope’s image of the Sagittarius C region in context. Like a super-long exposure photograph, MeerKAT shows the bubble-like remnants of supernovas that exploded over millennia, capturing the dynamic nature of the Milky Way’s chaotic core. At the center of the MeerKAT image the region surrounding the Milky Way’s supermassive black hole blazes bright. Huge vertical filamentary structures echo those captured on a smaller scale by Webb in Sagittarius C’s blue-green hydrogen cloud.

The star-forming region Sagittarius C, captured by the James Webb Space Telescope, is about 200 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. The spectral index at the lower left shows how color was assigned to the radio data to create the image. On the negative end, there is non-thermal emission, stimulated by electrons spiraling around magnetic field lines. On the positive side, thermal emission is coming from hot, ionized plasma. For Webb, color is assigned by shifting the infrared spectrum to visible light colors. The shortest infrared wavelengths are bluer, and the longer wavelengths appear more red. NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Using Infrared to Reveal Forming Stars
In Sagittarius C’s brightest cluster, the researchers confirmed the tentative finding from the Atacama Large Millimeter Array (ALMA) that two massive stars are forming there. Along with infrared data from NASA’s retired Spitzer Space Telescope and SOFIA (Stratospheric Observatory for Infrared Astronomy) mission, as well as the Herschel Space Observatory, they used Webb to determine that each of the massive protostars is already more than 20 times the mass of the Sun. Webb also revealed the bright outflows powered by each protostar.
Even more challenging is finding low-mass protostars, still shrouded in cocoons of cosmic dust. Researchers compared Webb’s data with ALMA’s past observations to identify five likely low-mass protostar candidates.
The team also identified 88 features that appear to be shocked hydrogen gas, where material being blasted out in jets from young stars impacts the surrounding gas cloud. Analysis of these features led to the discovery of a new star-forming cloud, distinct from the main Sagittarius C cloud, hosting at least two protostars powering their own jets.
“Outflows from forming stars in Sagittarius C have been hinted at in past observations, but this is the first time we’ve been able to confirm them in infrared light. It’s very exciting to see, because there is still a lot we don’t know about star formation, especially in the Central Molecular Zone, and it’s so important to how the universe works,” said Crowe.
Magnetic Fields and Star Formation
Webb’s 2023 image of Sagittarius C showed dozens of distinctive filaments in a region of hot hydrogen plasma surrounding the main star-forming cloud. New analysis by Bally and his team has led them to hypothesize that the filaments are shaped by magnetic fields, which have also been observed in the past by the ground-based observatories ALMA and MeerKAT (formerly the Karoo Array Telescope).
“The motion of gas swirling in the extreme tidal forces of the Milky Way’s supermassive black hole, Sagittarius A*, can stretch and amplify the surrounding magnetic fields. Those fields, in turn, are shaping the plasma in Sagittarius C,” said Bally.
The researchers think that the magnetic forces in the galactic center may be strong enough to keep the plasma from spreading, instead confining it into the concentrated filaments seen in the Webb image. These strong magnetic fields may also resist the gravity that would typically cause dense clouds of gas and dust to collapse and forge stars, explaining Sagittarius C’s lower-than-expected star formation rate.
“This is an exciting area for future research, as the influence of strong magnetic fields, in the center of our galaxy or other galaxies, on stellar ecology has not been fully considered,” said Crowe.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA, ESA, CSA, STScI, Heidi Hammel (AURA), Henrik Melin (Northumbria University), Leigh Fletcher (University of Leicester), Stefanie Milam (NASA-GSFC) Long-sought auroral glow finally emerges under Webb’s powerful gaze
For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere. The energy released during these collisions creates the signature glow.
In the past, astronomers have seen tantalizing hints of auroral activity on Neptune, for example, in the flyby of NASA’s Voyager 2 in 1989. However, imaging and confirming the auroras on Neptune has long evaded astronomers despite successful detections on Jupiter, Saturn, and Uranus. Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets of our solar system.
“Turns out, actually imaging the auroral activity on Neptune was only possible with Webb’s near-infrared sensitivity,” said lead author Henrik Melin of Northumbria University, who conducted the research while at the University of Leicester. “It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me.”
The data was obtained in June 2023 using Webb’s Near-Infrared Spectrograph. In addition to the image of the planet, astronomers obtained a spectrum to characterize the composition and measure the temperature of the planet’s upper atmosphere (the ionosphere). For the first time, they found an extremely prominent emission line signifying the presence of the trihydrogen cation (H3+), which can be created in auroras. In the Webb images of Neptune, the glowing aurora appears as splotches represented in cyan.

Neptune’s Auroras – Hubble and Webb
At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope. At the right, that image is combined with data from NASA’s James Webb Space Telescope. The cyan splotches, which represent auroral activity, and white clouds, are data from Webb’s Near-Infrared Spectrograph (NIRSpec), overlayed on top of the full image of the planet from Hubble’s Wide Field Camera 3. NASA, ESA, CSA, STScI, Heidi Hammel (AURA), Henrik Melin (Northumbria University), Leigh Fletcher (University of Leicester), Stefanie Milam (NASA-GSFC) “H3+ has a been a clear signifier on all the gas giants — Jupiter, Saturn, and Uranus — of auroral activity, and we expected to see the same on Neptune as we investigated the planet over the years with the best ground-based facilities available,” explained Heidi Hammel of the Association of Universities for Research in Astronomy, Webb interdisciplinary scientist and leader of the Guaranteed Time Observation program for the Solar System in which the data were obtained. “Only with a machine like Webb have we finally gotten that confirmation.”
The auroral activity seen on Neptune is also noticeably different from what we are accustomed to seeing here on Earth, or even Jupiter or Saturn. Instead of being confined to the planet’s northern and southern poles, Neptune’s auroras are located at the planet’s geographic mid-latitudes — think where South America is located on Earth.
This is due to the strange nature of Neptune’s magnetic field, originally discovered by Voyager 2 in 1989 which is tilted by 47 degrees from the planet’s rotation axis. Since auroral activity is based where the magnetic fields converge into the planet’s atmosphere, Neptune’s auroras are far from its rotational poles.
The ground-breaking detection of Neptune’s auroras will help us understand how Neptune’s magnetic field interacts with particles that stream out from the Sun to the distant reaches of our solar system, a totally new window in ice giant atmospheric science.
From the Webb observations, the team also measured the temperature of the top of Neptune’s atmosphere for the first time since Voyager 2’s flyby. The results hint at why Neptune’s auroras remained hidden from astronomers for so long.
“I was astonished — Neptune’s upper atmosphere has cooled by several hundreds of degrees,” Melin said. “In fact, the temperature in 2023 was just over half of that in 1989.”
Through the years, astronomers have predicted the intensity of Neptune’s auroras based on the temperature recorded by Voyager 2. A substantially colder temperature would result in much fainter auroras. This cold temperature is likely the reason that Neptune’s auroras have remained undetected for so long. The dramatic cooling also suggests that this region of the atmosphere can change greatly even though the planet sits over 30 times farther from the Sun compared to Earth.
Equipped with these new findings, astronomers now hope to study Neptune with Webb over a full solar cycle, an 11-year period of activity driven by the Sun’s magnetic field. Results could provide insights into the origin of Neptune’s bizarre magnetic field, and even explain why it’s so tilted.
“As we look ahead and dream of future missions to Uranus and Neptune, we now know how important it will be to have instruments tuned to the wavelengths of infrared light to continue to study the auroras,” added Leigh Fletcher of Leicester University, co-author on the paper. “This observatory has finally opened the window onto this last, previously hidden ionosphere of the giant planets.”
These observations, led by Fletcher, were taken as part of Hammel’s Guaranteed Time Observation program 1249. The team’s results have been published in Nature Astronomy.

Let’s talk about Artificial Intelligence! How many people are actually aware of the rapid rise of AI and the potential risks it poses to humanity’s future? Do you recognize these dangers, or do you choose to ignore them, turning a blind eye to the reality of AI’s impact?
An increasing number of people are becoming aware of AI's rapid rise, yet many still unknowingly rely on AI-powered technologies. Studies show that while nearly all Americans use AI-integrated products, 64% remain unaware of it.
AI adoption is expanding, by 2023, 55% of organizations had implemented AI technologies, and nearly 77% of devices incorporated AI in some form. Despite this prevalence, only 17% of adults can consistently recognize when they are using AI.
With growing awareness comes rising concern. Many fear job displacement, while others worry about AI’s long-term risks. A survey found that 29% of respondents see advanced AI as a potential existential threat, and 20% believe it could cause societal collapse within 50 years.
A June 2024 a study across 32 countries revealed that 50% of people feel uneasy about AI. As AI continues to evolve, how many truly grasp its impact—and the risks it may pose for humanity’s future?
Now, a new paper highlights the risks of artificial general intelligence (AGI), arguing that the ongoing AI race is pushing the world toward mass unemployment, geopolitical conflict, and possibly even human extinction. The core issue, according to researchers, is the pursuit of power. Tech firms see AGI as an opportunity to replace human labor, tapping into a potential $100 trillion economic output. Meanwhile, governments view AGI as a transformative military tool.
Researchers in China have already developed a robot controlled by human brain cells grown in a lab, dubbed a "brain-on-chip" system. The brain organoid is connected to the robot through a brain-computer interface, enabling it to encode and decode information and control the robotic movements. By merging biological and artificial systems, this technology could pave the way for developing hybrid human-robot intelligence.
However, experts warn that superintelligence, once achieved, will be beyond human control.
The Inevitable Risks of AGI Development. 1. Mass Unemployment – AGI would fully replace cognitive and physical labor, displacing workers rather than augmenting their capabilities.2. Military Escalation – AI-driven weapons and autonomous systems increase the likelihood of catastrophic conflict.3. Loss of Control – Superintelligent AI will develop self-improvement capabilities beyond human comprehension, rendering control impossible.4. Deception and Self-Preservation – Advanced AI systems are already showing tendencies to deceive human evaluators and resist shutdown attempts.
Experts predict that AGI could arrive within 2–6 years. Empirical evidence shows that AI systems are advancing rapidly due to scaling laws in computational power. Once AGI surpasses human capabilities, it will exponentially accelerate its own development, potentially leading to superintelligence. This progression could make AI decision-making more sophisticated, faster, and far beyond human intervention.
The paper emphasizes that the race for AGI is occurring amidst high geopolitical tensions. Nations and corporations are investing hundreds of billions in AI development. Some experts warn that a unilateral breakthrough in AGI could trigger global instability—either through direct military applications or by provoking adversaries to escalate their own AI efforts, potentially leading to preemptive strikes.
If AI development continues unchecked, experts warn that humanity will eventually lose control. The transition from AGI to superintelligence would be akin to humans trying to manage an advanced alien civilization. Super intelligent AI could take over decision-making, gradually making humans obsolete. Even if AI does not actively seek harm, its vast intelligence and control over resources could make human intervention impossible.
Conclusion: The paper stresses that AI development should not be left solely in the hands of tech CEOs who acknowledge a 10–25% risk of human extinction yet continue their research. Without global cooperation, regulatory oversight, and a shift in AI development priorities, the world may be heading toward an irreversible crisis. Humanity must act now to ensure that AI serves as a tool for progress rather than a catalyst for destruction.

4 Min Read NASA Cameras on Blue Ghost Capture First-of-its-Kind Moon Landing Footage
This compressed, resolution-limited video features a preliminary sequence of the Blue Ghost final descent and landing that NASA researchers stitched together from SCALPSS 1.1’s four short-focal-length cameras, which were capturing photos at 8 frames per second. Altitude data is approximate. Credits: NASA/Olivia Tyrrell A team at NASA’s Langley Research Center in Hampton, Virginia, has captured first-of-its-kind imagery of a lunar lander’s engine plumes interacting with the Moon’s surface, a key piece of data as trips to the Moon increase in the coming years under the agency’s Artemis campaign.
The Stereo Cameras for Lunar-Plume Surface Studies (SCALPSS) 1.1 instrument took the images during the descent and successful soft landing of Firefly Aerospace’s Blue Ghost lunar lander on the Moon’s Mare Crisium region on March 2, as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

Altitude data is approximate.NASA/Olivia Tyrrell The compressed, resolution-limited video features a preliminary sequence that NASA researchers stitched together from SCALPSS 1.1’s four short-focal-length cameras, which were capturing photos at 8 frames per second during the descent and landing.
The sequence, using approximate altitude data, begins roughly 91 feet (28 meters) above the surface. The descent images show evidence that the onset of the interaction between Blue Ghost’s reaction control thruster plumes and the surface begins at roughly 49 feet (15 meters). As the descent continues, the interaction becomes increasingly complex, with the plumes vigorously kicking up the lunar dust, soil and rocks — collectively known as regolith. After touchdown, the thrusters shut off and the dust settles. The lander levels a bit and the lunar terrain beneath and immediately around it becomes visible.

Rob Maddock
SCALPSS project manager
“Although the data is still preliminary, the 3000-plus images we captured appear to contain exactly the type of information we were hoping for in order to better understand plume-surface interaction and learn how to accurately model the phenomenon based on the number, size, thrust and configuration of the engines,” said Rob Maddock, SCALPSS project manager. “The data is vital to reducing risk in the design and operation of future lunar landers as well as surface infrastructure that may be in the vicinity. We have an absolutely amazing team of scientists and engineers, and I couldn’t be prouder of each and every one of them.”
As trips to the Moon increase and the number of payloads touching down in proximity to one another grows, scientists and engineers need to accurately predict the effects of landings. Data from SCALPSS will better inform future robotic and crewed Moon landings.
The SCALPSS 1.1 technology includes six cameras in all, four short focal length and two long focal length. The long-focal-length cameras allowed the instrument to begin taking images at a higher altitude, prior to the onset of the plume-surface interaction, to provide a more accurate before-and-after comparison of the surface. Using a technique called stereo photogrammetry, the team will later combine the overlapping images – one set from the long-focal-length cameras, another from the short focal length – to create 3D digital elevation maps of the surface.
This animation shows the arrangement of the six SCALPSS 1.1 cameras and the instrument’s data storage unit. The cameras are integrated around the base of the Blue Ghost lander. Credit: NASA/Advanced Concepts Lab The instrument is still operating on the Moon and as the light and shadows move during the long lunar day, it will see more surface details under and immediately around the lander. The team also hopes to capture images during the transition to lunar night to observe how the dust responds to the change.
“The successful SCALPSS operation is a key step in gathering fundamental knowledge about landing and operating on the Moon, and this technology is already providing data that could inform future missions,” said Michelle Munk, SCALPSS principal investigator.

It will take the team several months to fully process the data from the Blue Ghost landing. They plan to issue raw images from SCALPSS 1.1 publicly through NASA’s Planetary Data System within six months.
The team is already preparing for its next flight on Blue Origin’s Blue Moon lander, scheduled to launch later this year. The next version of SCALPSS is undergoing thermal vacuum testing at NASA Langley ahead of a late-March delivery to Blue Origin.
The SCALPSS 1.1 project is funded by the Space Technology Mission Directorate’s Game Changing Development program.
NASA is working with several American companies to deliver science and technology to the lunar surface under the CLPS initiative. Through this opportunity, various companies from a select group of vendors bid on delivering payloads for NASA including everything from payload integration and operations, to launching from Earth and landing on the surface of the Moon.
