Space Time
Also known as Boomerang, ESO 172-7.
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.
Boomerang Nebula image-field center is placed at J2000 RA 12.7 h, Dec -54.5° in Centaurus, at an adopted distance of 5,000 light-years.
Boomerang Nebula (preplanetary nebula; central source Boomerang Nebula, illuminating stellar system): projected footprint at the adopted distance 1.9 × 1.9 light-years; outer radius used for arrival 1 light-years.
A colored presentation of reflected light through a green-yellow filter. Visible color is not a temperature map of the exceptionally cold gas. 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.
