AI Study Finds Organic Molecules on Ceres Likely Came from Asteroid Impacts
The presence of organic molecules on the dwarf planet Ceres has been reassessed using AI analysis of data gathered by NASA’s Dawn spacecraft. Scientists have mapped regions rich in these compounds to determine whether they originated within Ceres or were delivered from external sources. Previously, it was believed that cryovolcanic activity on Ceres transported these molecules from beneath the surface. However, recent findings indicate that these organics were likely deposited by asteroid impacts rather than being internally generated.
Organic Deposits Mapped with AI Analysis
According to the study conducted, AI-driven analysis of Dawn’s data has provided a comprehensive map of organic-rich areas on Ceres. The research was conducted by scientists from the Max Planck Institute for Solar System Research (MPS) in Germany. Spectral imaging data showed that these organic deposits were not associated with sites of cryovolcanism. Ranjan Sarkar, a scientist involved in the study, said that sites of such organic molecules are actually rare on Ceres, and devoid of any cryovolcanic signatures. This challenges previous assumptions that cryovolcanic activity was responsible for bringing organic material to the surface.
Asteroids from the Outer Belt as a Possible Source
As reported, the study suggests that organic compounds on Ceres were likely delivered by low-velocity asteroid impacts. Simulations indicate that asteroids from the outer asteroid belt frequently collide with Ceres, but their relatively slow speeds prevent organic materials from being destroyed by heat. Martin Hoffmann, a researcher at MPS, explained to Nature Astronomy that “at none of the deposits do we find evidence of current or past volcanic or tectonic activity: no trenches, canyons, volcanic domes or vents.” This reinforces the idea that these molecules arrived externally rather than being produced within Ceres.
The findings support the possibility that organic molecules were present in the outer solar system early in its history and may have later been transported to inner planets, playing a role in the development of life on Earth.

Most early Europeans retained dark skin, hair, and eyes until approximately 3,000 years ago, as suggested by recent genetic research. Findings indicate that lighter features only became common in Europe during the Iron Age. Although the genetic markers for lighter pigmentation first appeared around 14,000 years ago, they remained relatively rare for thousands of years. Scientists suggest that lighter skin may have provided an advantage by aiding vitamin D production in regions with lower sunlight exposure. The research was conducted through an extensive analysis of ancient DNA samples from archaeological sites across Europe and parts of Asia.
Pigmentation Variations Over Time
According to a study published on the preprint server bioRxiv, genetic material from 348 ancient individuals was examined, with samples dating back as far as 45,000 years. The oldest belonged to the Ust’-Ishim individual from western Siberia, discovered in 2008, while another well-preserved genome came from the SF12 individual, who lived in Sweden around 9,000 years ago. Despite degradation in many samples, scientists utilised probabilistic phenotype inference and the HIrisPlex-S system to reconstruct pigmentation patterns.
Silvia Ghirotto, a geneticist at the University of Ferrara and the study’s senior author, stated in an email to Live Science that while lighter skin, hair, and eyes emerged sporadically in individuals over time, dark pigmentation remained dominant in parts of Europe well into the Copper Age. Some regions continued to see frequent occurrences of darker traits until the Iron Age.
Emergence of Lighter Features
The study found that lighter eye colours first appeared between 14,000 and 4,000 years ago, primarily in Northern and Western Europe. However, individuals with dark skin and dark hair still remained prevalent during that period. The genes responsible for lighter skin emerged in Sweden around the same time but remained rare initially.
Carles Lalueza-Fox, a palaeogeneticist at Barcelona’s Institute of Evolutionary Biology, who was not involved in the study, expressed surprise at the findings. He told Live Science that the persistence of darker pigmentation in some individuals until the Iron Age was unexpected. While the study maps out the emergence of these genetic traits, the reasons for their eventual dominance remain uncertain.
