Learn Astrology: A Clear, Real-Astronomy Guide

Astrology has a small number of moving parts that combine into something rich. There are the planets (including the Sun and Moon), which describe what is happening — identity, emotion, communication, love, drive. There are the twelve signs, which describe how each planet expresses itself. There are the twelve houses, which describe where in life it plays out. And there are the aspects, the angles between planets, which describe how the parts of you talk to one another.

If you are brand new, read the concept pages in order: begin with what astrology actually is, then the birth chart as a whole, then your Sun, Moon and Rising — the "big three" that sketch the fastest, truest outline of a person. From there, the houses, aspects and transits pages show how the chart deepens and how it moves over time. The planet pages can be read in any order, whenever you want to go deeper on one part of yourself.

Reading about astrology in the abstract only takes you so far. The moment it becomes genuinely useful is when you see it in your own chart — your real Sun, Moon and Rising, your planets in their actual signs and houses, the specific aspects that shape how you operate. Everything in this guide is designed to be read alongside your own map of the sky.

You can calculate that map for free in under a minute. Because the Rising sign and houses depend on your exact birth time, entering an accurate time unlocks the most personal layers of the chart. If you know it, use it; if you do not, you still get an accurate reading of every planet by sign.

Almost everything in a birth chart is a combination of just four kinds of thing. Once you can name them, the rest of astrology stops feeling like a wall of jargon and starts reading like a language with a simple grammar. Keep this short glossary in mind as you move through the guide — every concept and planet page below is really just exploring one of these four in depth.

The planets (including the Sun and Moon) are the actors; the signs are the costumes and accents they wear; the houses are the stages they perform on; and the aspects are the conversations they have with one another. A single placement — say, "Venus in Libra in the seventh house, trine the Moon" — is all four at once: a planet, in a sign, in a house, in aspect. Learn to read that sentence and you can read a chart.

We think you deserve the truth about what astrology is and is not. The astronomy is exact and verifiable — the planetary positions in your chart are real, calculated to the arc-second. The interpretation layered on top is a symbolic tradition thousands of years old, meant for insight and self-reflection, not scientific prediction. Held that way, it is a remarkably useful mirror: a vocabulary for noticing patterns, naming tendencies, and thinking about timing and growth.

Throughout this guide we keep those two layers distinct — what we compute versus what we interpret — so you always know which is which. That honesty is the whole point of Sigastra.

Most people meet astrology through their Sun sign — the "star sign" you get from your birthday alone. It is real and it matters, but it is genuinely only one twelfth of the picture. Your Sun describes your core identity; your Moon describes your inner emotional world; your Rising sign describes how you come across and frames the entire chart. Add the other planets, the houses they fall in and the aspects between them, and you move from a single label to a detailed portrait that actually sounds like you.

That is the journey this guide is built for. Start with the concepts that give you the map, read the planets to understand each part of yourself, and return to your own chart at every step. You do not need to memorise anything — you need only follow your curiosity, one page at a time, and let the picture fill in.
