Space Time
Also known as NGC 2174.
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.
Monkey Head Nebula image-field center is placed at J2000 RA 6.2 h, Dec 20.5° in Orion, at an adopted distance of 6,500 light-years.
Monkey Head Nebula (star-forming emission nebula; central source Monkey Head Nebula, embedded stellar population): projected footprint at the adopted distance 7.5 × 7.5 light-years; outer radius used for arrival 3.8 light-years.
The observation is a small pillar field inside NGC 2174, not the entire monkey-head outline. Infrared colors are assigned to invisible wavelengths. 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.
Compare the bright ionized boundary and dark obscuring dust with the infrared view of the same pillars. Publisher release: 7 February 2011; this is not the observing epoch.
