Zoobot: Foundation Model for Galaxies

Modern telescopes take far more images than astronomers could ever look through. Zoobot is a foundation model for automatically answering questions about galaxy images (like - does this galaxy have spiral arms?). By training on over 100M crowdsourced annotations from volunteers, Zoobot learns a semantic representation of each image that is useful for similarity search, anomaly detection, personalized recommendation, and (of course) efficient finetuning to new science questions.
