Space Time
Also known as Bubble Nebula, NGC 7635, Caldwell 11.
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.
Bubble Nebula (NGC 7635) image-field center is placed at J2000 RA 23.3 h, Dec 61.2° in Cassiopeia, at an adopted distance of 8,000 light-years.
Bubble Nebula (NGC 7635) (stellar-wind emission nebula; central source BD +60° 2522, massive wind-driving O star): projected footprint at the adopted distance 12.1 × 11.5 light-years; outer radius used for arrival 6 light-years.
The light field samples the published telescope composite at its angular scale and adopted distance. Color follows the source’s assigned wavelength palette. Shallow depth is illustrative, not measured tomography; foreground stars and telescope diffraction remain features of the source image.
