The map needs a landscape screen — there is no room for the sky and the controls side by side in portrait.
DESI DR1 · Bright Galaxy Survey
Every point is one galaxy, placed by its measured redshift. Positions are comoving, under the Planck18 cosmology; distances are shown in millions and billions of light-years.
Data: DESI Data Release 1 — Bright Galaxy Survey large-scale-structure catalogs (iron, v1.5). Galaxy names and morphologies come from HyperLEDA, cross-matched on the sky.
Built by John Rachlin, Khoury College of Computer Sciences, Northeastern University, in collaboration with Claude Code.
