Also known as NGC 3132, Eight-Burst Nebula, Caldwell 74.
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.
Southern Ring Nebula image-field center is placed at J2000 RA 10.1 h, Dec -40.4° in Vela, at an adopted distance of 2,500 light-years.
Southern Ring Nebula (planetary nebula; central source Southern Ring Nebula, illuminating stellar system): projected footprint at the adopted distance 1.8 × 1.6 light-years; outer radius used for arrival 0.9 light-years.
Webb near-infrared filters reveal nested shells; the adopted distance follows the approximate value in the 2022 release. The observed ring does not determine its three-dimensional shape. 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.
Dust and the faint central star become more prominent while the bright companion loses its dominance. Publisher release: 12 July 2022; this is not the observing epoch.
