![Architecture and workflow of AstroGenesis. Researchers interact with the system through a chatbot interface and select an appropriate DSRM corresponding to the astrophysical source class under investigation. Within the selected DSRM, a Supervisor Agent coordinates task execution through a Planner/Replanner and a set of specialized agents responsible for literature analysis, observational data retrieval, theoretical modeling, and research ideation. These agents operate using external tools which include, astrophysical tools, data-analysis modules, and pre-trained models to perform modeling of the data, etc. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/AstroGenesis.png?resize=1200%2C722&ssl=1)

The Role Of Minerals In Prebiotic Evolution: Implications For Identifying Worlds With The Potential For Life’s Origin
[Fundamental Research] Understanding the origin of life requires explaining how abiotic molecules transitioned into the first living systems within plausible geological settings. Increasing evidence suggests minerals as active participants in […]

![First detection of fully deuterated methanol in interstellar space This composite image shows the Perseus molecular cloud, which is located about 1,000 light-years from Earth. A rare form of the organic alcohol methanol has been observed around at least one of the very young stars still embedded within it. This is the first time this molecule has been detected in space, as shared by the ALMA COMPASS Large Program (Complex Organic Molecules in Protostars with ALMA Spectral Surveys).
