Also known as IC 1848, W5, Embryo Nebula, Sh2-199.
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.
Soul Nebula image-field center is placed at J2000 RA 2.9 h, Dec 60.4° in Cassiopeia, at an adopted distance of 6,500 light-years.
Soul Nebula (star-forming emission nebula; central source Soul Nebula, embedded stellar population): projected footprint at the adopted distance 249.7 × 283.8 light-years; outer radius used for arrival 141.9 light-years.
Spitzer assigned infrared colors: blue 3.6 microns, green 8 microns and red 24 microns. The image records an archived star-forming region, not its current appearance. 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.
