Sources and further reading

The credibility layer behind Xosmology.

Xosmology is written to be readable first. This page collects reputable places to go deeper: space agencies, universities, museums, public-health organisations, encyclopaedias and scholarly references.

These links are not meant to turn the site into an academic paper. They are here so readers can check the ground beneath the Story, Method, People and Practice pages.

This is a first public source list, not a final bibliography. It should grow as pages are reviewed and specific claims are source-checked.

How sources should be used

Xosmology should use external sources as support, not as decoration. Major factual claims should be checked against high-quality sources. Where evidence is uncertain, the site should say so plainly.

We should avoid relying on random blogs, sensational media, culture-war material, AI-generated pages or wellness sources making exaggerated claims.
