Crab Nebula
M1 · NGC 1952
The remnant of the supernova recorded by astronomers in 1054 CE, powered by a central pulsar.
Why it matters at 0.75–5 µm
Synchrotron emission produces a smooth power-law continuum across the SPHEREx band.

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.
