Sky and Astrology Atlas

This atlas is a reference collection with two layers: on one side the astronomy of sky events and concepts, on the other the concepts of astrological culture — side by side, without being mixed together.

Scope: two layers, one atlas

The astronomy layer holds eclipses, planetary motion, meteor showers, constellations and the basic concepts of the science of the sky. The culture layer sets out elements such as the signs, planetary symbolism and astrological period concepts within their historical and cultural context. The two layers are clearly separated visually as well; in every record you can see plainly which knowledge rests on observation and which on tradition.

How a record is built

A typical record in the culture layer answers three questions. What is actually happening in the sky? How has this phenomenon been interpreted in culture? And what do we see when we look at it with scientific method? This structure aims to set out the evidence without belittling a reader who believes. Astrology is not a scientific discipline; but knowing where its concepts come from helps you read the culture better.

Filters and connections

You can sift the records by layer, astronomy or culture, and by type of subject: sky events, celestial bodies, concepts, symbols. There are paths from an eclipse record to the relevant observation guide, and from a sign record to cognitive concepts such as the Barnum effect. If you would rather learn the subject in sequence, the Sky, Mind and Culture section and the Academy will keep you company.

Frequently asked questions

Do the astrology records endorse astrology?

The records describe astrological concepts as a cultural phenomenon, with respect but within an evidential frame. It is stated plainly that astrology is not a scientific discipline; the aim is not to judge but to help you understand.

Is equipment needed for observation?

Most sky events can be watched with the naked eye; the records include practical notes on how each event is observed. A spot away from light pollution is often worth more than a telescope.

Are horoscope readings published here?

No. The atlas describes the cultural origins and the symbolism of the signs; it does not produce daily readings.
