Every aspect, with its origin

One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Image field at the adopted distance

Wizard Nebula (star-forming emission nebula; central source Wizard Nebula, embedded stellar population): projected footprint at the adopted distance 88.6 × 84.2 light-years; outer radius used for arrival 44.3 light-years.

Sky-plane structure with a display depth

This is an emission-line composite of the NGC 7380 cluster and surrounding nebula; the published colors encode selected filters. Projected structure follows the credited observation at its published angular scale and an approximate adopted distance. Shallow depth is illustrative, not measured tomography. The source palette is preserved; brightness is adjusted for the navigable view.

Methodmeasured sky-plane structure with constrained display depth
LimitEmission points and knots are deterministic presentation samples, not individually catalogued gas parcels.

What is not measured

  • Appearance: a reconstruction from measurements, not a direct observation. Sky-plane structure with a display depth. Emission points and knots are deterministic presentation samples, not individually catalogued gas parcels.
