A knowledge platform for everything above Earth — astronomy, space, the night sky, celestial events, mythology, and astrology as a clearly separate cultural tradition.

Astronomy is presented as scientific, evidence-based, and sourced. Astrology is presented as cultural, symbolic, and interpretive — never as proven science.
