Extended description
Astronism gives a central role to the emotion referred to as astronality. This entails a person's spiritual and/or existential connection to the astronomical world, perceived through a separable religious and philosophical system, both underpinned by a cosmocentric worldview. A cousin to both astrology and astrotheism, Astronists differ by their focus on cultivating their connection to The Cosmos as the highest priority. Astronism traces its lineage back to the Upper Palaeolithic period of the Stone Age in Cometan's historiography of the Astronic tradition during which time the Aurignacians first linked religious ideas and beliefs to the night sky. 
2. a philosophical system dispensing theories on eschatological, soteriological, and ethical topics involving the astronomical world to form a branch of philosophy called cosmontology.
  • a system of thought bestowing prime importance to astronomical rather than human or divine matters.
3. the preoccupation of an individual, or a society with the exploration of outer space, especially when considered as possessing moral or religious significance.
4. (often astronism) the belief that the astronomical world is both a source and a receptor of human faith and existential meaning and belief.
5. (functional definition) a forum and vehicle for the discussion and promotion of beliefs and practices relating humanity to the astronomical world.
