Galaxy Zoo Evo Unveils 1 Million Human-Annotated Galaxy Images, Advancing Astronomical Research

A significant new contribution to astrophysics, “Galaxy Zoo Evo,” has released a dataset of one million human-annotated galaxy images, according to recent arXiv submissions. This comprehensive collection has already garnered positive reviews for the NeurIPS Datasets and Benchmarks 2025 conference.

The “Galaxy Zoo Evo” project leverages the power of citizen science, where volunteers worldwide contribute to classifying galaxy images. The newly released data contains detailed annotations on galaxy morphology, features, and potential evolutionary stages, captured by human observers. This granular detail is crucial for improving astronomical models and understanding complex, nuanced aspects of galaxies that are challenging for automated systems alone.

Researchers anticipate that this vast dataset will be instrumental in training advanced AI models and uncovering new insights into galaxy formation, evolution, and the large-scale structure of the universe. The project highlights the enduring value of human observation in the digital age of astronomy.
