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.
Egg Nebula image-field center is placed at J2000 RA 21 h, Dec 36.7° in Cygnus, at an adopted distance of 1,000 light-years.
Egg Nebula (preplanetary nebula; central source Egg Nebula, illuminating stellar system): projected footprint at the adopted distance 0.3 × 0.3 light-years; outer radius used for arrival 0.2 light-years.
The February 2026 Hubble release combines optical and infrared observations. The hidden central star is not drawn as an unobscured object. 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.
