Description
17,736 galaxies are labeled by citizen scientists through the Galaxy Zoo 2 project. The catalog includes right ascension, declination, redshift, and Galaxy Zoo 2 labels for each entry. Leung et al. published this dataset in 2018, and it is hosted by MultimodalUniverse on Hugging Face.
Use Cases
Classify galaxy morphologies based on citizen-scientist labels.
Analyze the spatial distribution of galaxies based on right ascension and declination coordinates.
Study the relationship between galaxy redshift and morphological type.
Train machine learning models for automated galaxy classification.
Strengths
Contains 17,736 labeled galaxy records.
Includes core astronomical features: right ascension, declination, and redshift.
Leverages labels from the large-scale Galaxy Zoo 2 citizen science project.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is known, but other scale metrics like file size and formats are unknown.
Description metadata is limited; actual data quality requires manual inspection after download.
Provenance
Source
Galaxy Zoo 2 project, via Leung et al. (2018).
Collection Method
