Exploring the Possibility of Life on Dwarf Planet Ceres: Scientists Provide Insight
Scientists Discover Organic Substances Necessary for Life on Dwarf Planet Ceres
Recent research conducted by scientists has revealed that some organic substances crucial for life may have originated in an ocean on the dwarf planet Ceres. Ceres, the largest object in the asteroid belt, is known to have saltwater oceans beneath its icy surface, containing salt and hydrocarbons.
Researchers have identified areas rich in organic chemicals called aliphatics covering hundreds of square kilometers around the Ernutet crater on Ceres. These aliphatic components may have emerged on the surface relatively recently due to the rapid degradation caused by radiation exposure in space.
Led by Prof. Dr. Maria Cristina De Sanctis, a planetary scientist at the National Institute of Astrophysics in Italy, the team performed experiments in the laboratory using organic chemicals similar to those found on Ceres. The mixture, resembling the aliphatic organics near the Ernutet crater, was subjected to intense ultraviolet radiation and fast-moving ions to simulate the effects of space erosion on organic molecules.
The results of the experiment indicate that the aliphatic compounds were not resistant to radiation, even when combined with protective clay-like substances. It was determined that these hydrocarbons around the Ernutet crater could have arrived in the region approximately 10 million years ago.
Many simulations imply that the organic molecules were not brought by comets or smaller asteroids but were likely formed internally within Ceres. This suggests that the geology of Ceres produced these organic components in a relatively recent timeframe.
The team highlighted the Ernutet crater on Ceres as a potential site for further research into habitable or life-supporting environments. The organic compounds discovered in this area may have evolved over Ceres’ deep ocean’s lifespan, lasting several hundred million years.
The study, published in the journal Science Advances, opens up new possibilities for understanding the origin and existence of organic substances necessary for life beyond Earth. Further exploration of Ceres and its unique characteristics could provide valuable insights into the potential for habitability on other celestial bodies.
