Triangulum Galaxy

M33 · NGC 598

The third-largest member of the Local Group, with prominent H II regions like NGC 604.

Why it matters at 0.75–5 µm

Star-forming knots stand out in the 3.3 µm PAH channels.

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.
