  • Zodiac and Retrograde Motion: Astronomy, not Astrology!

    Today we’re going to very quickly go over the zodiacal constellations, the constellations that we see in the sky along the path of the ecliptic, which is where we see the planets, the Moon, and the Sun, roughly speaking at least. We’ll start by taking a look at the planets at sunset in June. We…
