“SDSS Halo Star Cloud | 3D Galactic Rotation Visualization (w/ Kosmosphar 1978 Soundtrack)”

This is a 10-minute, 3D animated visualization of halo stars orbiting the Milky Way, constructed using real astronomical data from the Sloan Digital Sky Survey (SDSS).

✅ What you're seeing:
10,000+ stars selected from SDSS spectroscopic catalogs

Stars plotted in Galactocentric Cartesian coordinates, with distance estimated from g-band magnitude (assuming M ~ 4.5)

Colors represent either metallicity [Fe/H], redshift, or g-r color index depending on data availability

Velocity vectors shown for stars with motion data

DBSCAN clustering identifies possible halo substructures

Camera performs a spiral rotation in 3D space, simulating flyby around the Galactic halo

🎵 Soundtrack: Excerpt from Kosmosphar (1978) album "Gravitationswellen", a vintage analog electronic journey that fits the deep-space visual vibe.
