Andromeda Galaxy
M31 · NGC 224
The nearest large spiral galaxy and the most distant object easily visible to the naked eye.
Why it matters at 0.75–5 µm
At 1–2 µm the old stellar population dominates and the bulge brightens; longer wavelengths trace warm dust in the spiral arms.

Builds a 4-epoch × 102-channel input from real SPHEREx L2 exposures here (64×64 at 6.15″/px), then runs the ONNX model in your browser to pick the best viewing channels and score anomalies and motion. The first run at a position takes 1–2 minutes.
