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

Flame Nebula (star-forming emission nebula; central source Flame Nebula, embedded stellar population): projected footprint at the adopted distance 12.7 × 13.3 light-years; outer radius used for arrival 6.6 light-years.

Appearance Reconstructed

Sky-plane structure with a display depth

The VISTA field includes surrounding Orion nebulosity. The destination aperture emphasizes the Flame; bright stellar halos are observation features. 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.

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.
