TheGalaxyDB: 22 Million Galaxies, Rendered
A browser-based galaxy catalog that cross-matches five astronomical datasets and renders morphological types with its WebGL engine, GLEN.
Field notes
The catalog is assembled by merging SDSS DR17, HyperLEDA, HECATE, PGC2003, and Mangrove records into unified entries with morphology, redshift, physical properties, and source cross-references. Its GLEN renderer uses GLSL shaders and measured classification parameters: spiral-arm winding changes across Sa–Sc, while bar strength distinguishes barred types. The homepage reports roughly 14 million spiral and barred-spiral objects, with records marked spectroscopic or photometric.
