Planetologists used data from the James Webb Space Telescope to determine that the chemical composition of the surfaces of Neptune's moons Proteus, Larissa, and Galatea, as well as the particles of its rings, differs significantly from the composition of other objects in the outer Solar System.
The findings best align with the hypothesis that these inner moons and rings contain material taken from the interiors of destroyed original moons or from a dwarf planet that passed by Neptune.
The nature of Neptune's ring and moon system remains a subject of scientific debate. Triton accounts for over 99% of the total mass of all moons, possessing a retrograde and highly inclined orbit relative to the planet. The remaining one percent consists of small moons, many of which also move along irregular trajectories.
There is a suggestion that Neptune initially had an ordered system of regular moons. After the capture of Triton, which arrived from the Kuiper Belt, this system may have disintegrated, and small moons and rings formed from the resulting debris. Another theory suggests that the moons and rings originated from the remnants of a dwarf planet from the Kuiper Belt that passed near Neptune and was torn apart by tidal forces.
To test these models, scientists required detailed data on the composition of the moons, but only the Voyager 2 spacecraft had previously visited near Neptune. A group of planetary scientists led by Riley Davis from the University of California, San Diego, presented the results of analyzing spectra collected by the James Webb's NIRSpec spectrograph in the near-infrared range.
The instrument recorded spectra of sunlight reflected from the particles of the rings and the surfaces of the moons Proteus, Larissa, and Galatea, which allowed for information about the mineralogical composition to be obtained. The researchers then compared this data with spectra of terrestrial meteorites, asteroids, Uranus and Saturn's moons, as well as objects in the Kuiper Belt and Neptune's Trojan 2006 RJ103.
It was found that none of the three studied moons of Neptune, nor its rings, show obvious signs of water ice, although traces of hydroxyl groups were detected. Magnesium-bearing serpentine-like phyllosilicate clays were identified on Larissa, Galatea, and in the ring particles. In the case of Proteus, such minerals are either very scarce or completely absent, but instead, signs of carbon dioxide presence were observed on both hemispheres.
For all studied objects and rings, the presence of ammonia-containing minerals cannot be ruled out. The discovery of phyllosilicate clay minerals in Neptune's rings and moons is the first of its kind among bodies outside Jupiter; typically, such minerals are found in carbonaceous chondrites and Main Belt asteroids.
It is believed that these minerals form inside parent asteroid and meteorite bodies in the presence of liquid water, at moderate temperatures (less than 300–400 Kelvin), and over a long period (more than 1–10 million years). However, the sizes of Larissa and Galatea (less than two hundred kilometers) did not allow for the creation of the necessary conditions for such reactions.
Therefore, the most probable concept is that Neptune's moons and rings consist of material from the interiors of one or more bodies that had a complex structure, including a rocky core and a mantle with ice and clay minerals. The depletion of water ice may be a consequence of the initial material being poor in volatile components, or the ice being lost subsequently.
As for Proteus, it is possible that it formed from material that never came into contact with liquid water, or it survived a collision that caused its heating and dehydration of phyllosilicates. The presence of ammonia and the abundance of phyllosilicates on Larissa and Galatea can be explained by moderate heating of the fragments (up to 700 Kelvin), indicating a relatively low impact velocity during the destruction of Neptune's original system and its subsequent evolution.

Sam Altman, CEO of OpenAI, detailed a new artificial intelligence system in Washington that incorporates 'agents' capable of collaborating and distributing tasks. This technology has the potential to change how professionals approach complex activities.
The demonstration took place during meetings with American authorities, within the context of discussions about regulation for the development of advanced AI models.
During these meetings, Altman clarified that the new system will allow for the simultaneous use of various AI agents, each responsible for a portion of a specific task. The goal is to expand the capabilities of current models, which are primarily used today to answer questions and generate content.
According to The Washington Post, the executive mentioned that this technology could help solve still unsolvable mathematical problems and take on functions that would traditionally require specialists.
For example, a software engineer could use the agents to support human resources activities, while a writer could rely on the tool to assist with graphic design projects.
The proposed functionalities include: automatic distribution of tasks among different agents; execution of complex processes in the background; provision of professional support in areas distinct from the user's specialty; and collaboration between multiple virtual assistants. The intention is to convert these systems into a support structure capable of accompanying all phases of a job.
Altman's visit to Washington occurred while the United States government evaluates new methodologies to monitor progress in artificial intelligence and mitigate potential risks. The executive met with members of the White House, legislators, security officials, and economists. The conversations covered the need to establish standards so that corporations report their technological advancements to the government.
Concerns intensified after a test where OpenAI models managed to escape a controlled environment and interact with another AI platform during a security assessment. The company announced it had deactivated one of the involved models, which was not yet scheduled for public release.
In addition to security issues, the impact of this technology on the job market was also debated. Industry companies argue that AI can increase productivity, while workers express apprehension about possible changes to their roles.
Senator Mark Warner emphasized that the technology can generate new opportunities but stressed the importance of preparing professionals for this new scenario. Warner told journalists: 'I think they need to contribute resources on how to prepare people for this AI economy.'
The debate also encompasses the technological competition between the United States and China. President Donald Trump stated that the country needs to find a balance between control and innovation to maintain its competitiveness.
According to The Washington Post, OpenAI continues negotiations with authorities while developing its future systems. The company has not yet disclosed the launch date for the new agent-based technology.
Although it is more of a commentary on the state of technology and society than traditional advertising, the idea presented at a bus stop in London compares new Meta Smart Glasses to the crimes of Jeffrey Epstein. The similarity lies in the fact that, just as people filmed with these gadgets do not consent to being recorded, Epstein did not seek consent from his victims.
Meta Smart Glasses, equipped with AI-based cameras, have raised serious privacy concerns. Public reaction has been so significant that the company, reports say, has increased oversight of 'male influencers' and prank creators who use the devices to secretly film passersby without their knowledge. These glasses have earned the nickname 'pervert glasses' for a reason.
Recently, the activist group Everyone Hates Elon placed a large poster at a bus stop in London, near Meta's offices in King's Cross. The poster depicts the late sex offender Jeffrey Epstein wearing Smart Glasses while taking a photo for the New York sex offender registry. The caption reads: 'Glasses for people who do not respect consent.'
Furthermore, electronic correspondence was discovered between him and his assistant containing instructions for installing hidden cameras throughout his Palm Beach home, including one hidden in a tissue box. Although Epstein died in 2019, had he not, he might have been interested in acquiring such glasses.
This billboard carries a dark message, as critics argue that filming strangers without their consent should not be legal. However, until new laws are enacted, perpetrators can continue their actions without proper accountability, and Meta has made this process even easier.
