Everything Above Earth.

Asteria Star is a knowledge platform for everything above Earth — astronomy, space exploration, the night sky, celestial phenomena, mythology, observation, astrophotography, telescopes, and astrology as a separate cultural tradition.

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