Data

Every claim in the archive is traceable. Here's where the data comes from.

I

Astronomical Sources

All celestial data in the archive is derived from professional-grade astronomical databases. These are the same sources used by space agencies, observatories, and academic researchers worldwide.

NASA JPL Horizons Planetary ephemeris, orbital elements, and positional data for all solar system bodies. The definitive source for high-precision celestial mechanics.
ssd.jpl.nasa.gov
Swiss Ephemeris High-precision astronomical calculations used by professional astrologers and researchers. Sub-arc-second accuracy for planetary positions spanning millennia.
NASA Eclipse Website Fred Espenak's eclipse catalog, the gold standard for eclipse data. Comprehensive records of solar and lunar eclipses spanning five millennia.
eclipse.gsfc.nasa.gov
IAU The International Astronomical Union. Official constellation boundaries, celestial nomenclature, and standardized astronomical definitions.

Historical Sources

Every world event in the archive is independently verifiable. We draw from multiple layers of historical scholarship to ensure accuracy across four and a half millennia of human history.

Primary Sources Contemporary accounts, government records, treaties, and first-hand documentation from the period in question.
Academic Databases JSTOR, Google Scholar, and university press publications for peer-reviewed historical research and analysis.
Reference Works Encyclopedia Britannica and Oxford Reference for cross-verification of dates, figures, and established historical consensus.
Regional Archives Specialized sources for pre-modern events: Babylonian clay tablets via British Museum records, Chinese dynastic histories, and Roman historical sources including Livy, Tacitus, and Cassius Dio.

Data Format

Each event in the archive is structured as a complete record containing the following fields:

Year The year of the event, from 44 BCE to 2026 CE
Date Specific date when available
Celestial Event The name of the astronomical alignment
Celestial Type Eclipse, conjunction, opposition, square, retrograde, equinox, or ingress
Symbol Astrological glyph for the alignment
World Event The corresponding historical occurrence
Category Geopolitical, financial, scientific, cultural, religious, pandemic, or deaths
Description Narrative context for the event
Cosmic Link Analysis of the celestial-terrestrial correlation
Historical Parallel Connections to similar alignments and events across history

The full dataset contains 128 events spanning 44 BCE to 2026 CE, making it one of the most comprehensive publicly available archives mapping celestial alignments to world history.

Open Data Philosophy

We believe celestial history should be accessible to everyone. The archive is free, with no paywalls or algorithmic gatekeeping. All astronomical data used is publicly available from the sources listed above. We encourage independent verification.

If a claim in this archive doesn't hold up to scrutiny, we want to know. The value of this project depends entirely on the integrity of the data. Every celestial position can be recalculated. Every historical event can be cross-referenced. That is by design.

We are not in the business of telling anyone what to believe. We are in the business of presenting the data clearly enough that the patterns speak for themselves.

The patterns in this archive are not articles of faith. They are observations, laid out in the open, for anyone to examine, question, and interpret as they see fit. That is the only honest way to do this.
