New study suggests organic molecules on Ceres came from Asteroids, not volcanoes
Recent findings from NASA's Dawn spacecraft have led scientists to reconsider how organic molecules ended up on the dwarf planet Ceres. Previously, it was believed that cryovolcanic activity—volcanoes that erupt icy materials—in Ceres' interior brought these organic compounds to the surface. However, new research from the Max Planck Institute for Solar System Research (MPS) in Germany suggests a different origin.
The study indicates that organic molecules on Ceres were likely deposited by asteroid impacts rather than being formed internally through volcanic processes. By analyzing spectral imaging data from the Dawn spacecraft, scientists mapped areas rich in organic materials and found they were not located near cryovolcanic sites.
Ranjan Sarkar, a scientist involved in the study, pointed out that these organic deposits are rare and not linked to volcanic features, challenging the earlier belief that volcanoes were responsible for bringing organic materials to the surface.
Further analysis suggests that slow-moving asteroids from the outer asteroid belt could be the source of these organic compounds. Due to their low impact speeds, the heat generated during collisions is insufficient to destroy the organic molecules, allowing them to remain on Ceres' surface.
Martin Hoffmann, another researcher at MPS, highlighted that there is no evidence of volcanic or tectonic activity in the areas where these organic compounds are found. This supports the theory that the organic materials were delivered from space by asteroid impacts rather than from within the planet itself.

Eighteen properties, including the Reliance Centre in Mumbai's Ballard Estate, fixed deposits, bank balance and shareholding in unqouted investments of Reliance Anil Ambani Group have been provisionally attached under the Prevention of Money Laundering Act (PMLA), they said.
Another set of seven properties of Reliance Infrastructure Ltd, two properties of Reliance Power Ltd, nine properties of Reliance Value Service Private Ltd, fixed deposits in the name of Reliance Value Service Private Ltd, Reliance Venture Asset Management Private Lt, Phi Management Solutions Private Ltd, Adhar Property Consultancy Pvt Ltd, Gamesa Investment Management Private Ltd and investments made in unquoted investment by Reliance Venture Asset Management Private Ltd and Phi Management Solutions Private Ltd have also been attached, they said.
The ED had earlier attached properties worth over Rs 8,997 crore in the bank fraud cases related to Reliance Communications Ltd (RCOM), Reliance Commercial Finance Ltd, and Reliance Home Finance Ltd.
The total attachment in the case against the Reliance Group is now Rs 10,117 crore.
