Art: the nebula, the exact colours everywhere (representative colour), the street detail in the city lights, and the brand stars. Stars.

Everything else in the galaxy world (the disk, bar, arms, dust and the millions of stars) is procedural, generated on the GPU at load time. Changes (CC BY 4.0 s.3(a)(1)(B)): since v5.1 "SPECTRUM" the ESO/S. Brunier panorama (mw-2k/mw-4k.jpg) is colour graded at runtime (teal/violet split-tone, desaturated; brightness structure kept). The file itself is unchanged. All galaxy colours are representative colour. ------------------------------------------------------------------------ assets/sun/ Sun (web/public/assets/sun/*.jpg) Source: NASA Solar Dynamics Observatory (SDO), AIA and HMI browse images of 27 Sep 2026, 13:55-14:05 UT, https://sdo.gsfc.nasa.gov/assets/img/browse/2026/09/27/ (AIA 94, 131, 171, 193, 211, 304, 335, 1600, 1700 A; HMI continuum).

On screen: representative colour per wavelength (not NASA's colour tables, not true colour). The corona beyond ~1.25 solar radii is an artistic extension of the real limb brightness (procedural noise).
