Image-field position and adopted distance
Rho Ophiuchi image-field center is placed at J2000 RA 16.4 h, Dec -24.4° in Ophiuchus, at an adopted distance of 390 light-years.
Also known as Rho Ophiuchi cloud complex, Rho Oph.
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.

Rho Ophiuchi (star-forming emission nebula; central source Rho Ophiuchi, embedded stellar population): projected footprint at the adopted distance 0.8 × 0.7 light-years; outer radius used for arrival 0.4 light-years.
This is Webb’s close field around young stars in Rho Ophiuchi, not the entire cloud complex or the wide Antares region. Infrared bands are assigned visible colors. 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.
