Lengthening day: If it seems as if each day is longer than the last, you’re right. But that’s just because Earth is slowing down ever so slightly every day. Gravitational tugs from other celestial bodies (principally the moon and the sun) are causing the “great slowdown,” as my colleague David Ropeik explained back in 2001. It’s thought that when the moon formed, billions of years ago, a full day was six hours long, and that the day lasted less than 23 hours when dinosaurs ruled the earth. Nowadays, leap seconds are periodically added to keep atomic clocks in sync — most recently at the end of 2008.
Based on old astrology I am a Gemini, but I just saw today that as a result of the precession of the equinoxes I am really a Taurus according to modern astronomy. They show the updated Zodiac chart in the video at the link below.
“Back in the days of Babylonian soothsayers, the sun might have been in the constellation Capricorn at this time of year. But due to the changing tilt of Earth’s axis, it’s actually in Sagittarius right now.
Over the course of thousands of years, Earth’s axis wobbles like a top, and as a result the apparent position of the sun against the constellations varies. The boundaries of the constellations have become more sharply defined as well, which means the sun doesn’t spend equal amounts of time in each of the zodiacal “signs.” In fact, the sun passes through a 13th constellation — Ophiuchus the serpent bearer — which throws off the whole traditional 12-house system that astrologers swear by.
