Overview
- AnomalyMatch processed nearly 100 million Hubble Legacy Archive cutouts in about two and a half days, producing a ranked list of unusual sources.
- Expert review confirmed roughly 1,300 true anomalies, more than 800 of which had not appeared in the scientific literature.
- Most finds are galaxies in mergers or interactions, with additional examples including gravitational lenses, jellyfish systems, clumpy galaxies, and edge‑on planet‑forming disks.
- The study highlights dozens of objects that defy current classification and flags 86 candidate new gravitational lenses for further investigation.
- The work marks the first systematic anomaly hunt across Hubble’s archive, is published in Astronomy & Astrophysics, and is positioned for use with Euclid, Rubin, and NASA’s Roman Telescope.
