ESA AI Tool Identifies 1,400 Anomalies in Hubble Archive, Expanding Astronomical Knowledge
The European Space Agency (ESA), in collaboration with NASA, has utilized an artificial intelligence tool named AnomalyMatch to analyze nearly 100 million image cutouts from the Hubble Legacy Archive. This effort led to the identification of approximately 1,400 anomalies, including gravitational lenses, galaxy mergers, and other objects that challenge existing classification schemes. The AI tool ranked images based on their unusual characteristics, and researchers David O'Ryan and Pablo Gómez subsequently reviewed and cataloged these anomalies. This process, which took about two and a half days, resulted in the discovery of over 800 objects not previously documented in scientific literature.
