KosmosAstrology is the art of interpreting the sky at the moment of your birth: the Sun, Moon, planets, Ascendant, houses, and the angles between them. In this section we explain the building blocks step by step, no prior knowledge required and no promises about fate. You'll learn how to find your Ascendant and Moon sign, what the twelve houses have to do with different areas of your life, how aspects such as the trine and the square work, and why the four elements sort the signs so well.
You'll also find current articles on the major movements in the sky: the Saturn return, Jupiter in Leo, the lunar nodes, eclipses, and Mercury retrograde. Every article treats astrology as a mirror for self-reflection. Once you know the tools, you look at your own birth chart with new eyes, and that is exactly what the personal Birth Chart Book is for.

Frequently asked questions about Astrology
What do I need to read my birth chart?
Your date of birth, time of birth, and place of birth. Without the time, you can still determine the Sun, usually the Moon, and all the planets in their signs, but the Ascendant and houses remain open. The articles on the Sun, Moon, and Ascendant and on the twelve houses are a great place to start.
Is astrology a science?
No. Astrology is an interpretive tradition thousands of years old, not a natural science. Planetary positions are calculated with astronomical precision, but their interpretation is an invitation to self-reflection, not a prediction. That is how we approach it in every article and book.
Where is the best place to start with astrology?
With the Big Three: your Sun sign, Moon sign, and Ascendant. The free calculator shows them in seconds, and the articles in this section explain what they mean. After that, houses, aspects, and planets are worth exploring, in that order.
