Astrology

Zodiac signs, eclipses, retrogrades and moons: where the ideas came from, what is actually happening overhead, and what the evidence says.

• Mercury Retrograde: What Is Actually Happening Up There Three or four times a year, Mercury seems to stop and back up across the sky. It never does. The truth is geometry, and an ancient puzzle.
• Scorpio: The Scorpion Is One of the Oldest Signs in the Sky Babylonian astronomers named its burning sting some three thousand years ago. Since then it has been a Greek assassin, a dragon's tail and Māui's fishhook.
