Astrology or cosmology is not specifically mentioned in the Torah, and there are two commandments which have been used by some authorities as a basis to forbid the practice:
"You shall not practice divination or soothsaying." (Leviticus 19:26)
"When you enter the land that the ETERNAL your God is giving you, you shall not learn to imitate the abhorrent practices of the nations. Let no one be found among you who...is an auger, a soothsayer, a diviner, a sorcerer, one casts spells.....For anyone who does these things is abhorrent to the ETERNAL..." (Deuteronomy 18:9-12).
