The positions of stars during the 1919 total solar eclipse, which was used to prove Einstein's ... [+] theory that space-time bends light. Astrologers will make money from April 8’s total solar eclipse—but they may end the day wondering what to believe. After presumably confusing astronomy and astrology, and then being forced to run with it, marketing majors are this month busily sending press releases to journalists with refrains like “the stars are aligned” while detailing eclipse-viewing events on April 8. Some promise tarot card readers and tooth gem vendors, others the chance to “embrace changes and new beginnings” during “immersive astrological experiences.” However, Western astrologers could be in for a nasty shock on April 8 when the sun appears in the “wrong” sign of the zodiac. Astrologically Significant? Despite simply little more than a line-of-sight phenomenon, solar eclipses are, apparently, astrologically significant—and this one certainly will be to any believer in astrology who actually looks at the sky and the stars during totality. Astrologers and everyone else within the path of totality—the 115-mile-wide shadow of the
moon sweeping across parts of 15 U.S. states on April 8, will experience darkness in the day and see a totally eclipsed sun. For up to 4 minutes and 26 seconds, stars will be visible. But from a believer in astrology’s point of view, they will be the wrong stars. NOTE: This article only applies to those that are in the path of totality. If you’re not within the path of totality (which you can check on this interactive map , this eclipse simulator and in this eclipse look-up then you’ll see just a partial solar eclipse, which requires solar safety glasses at all times and is not rare or unusual. Stars During Totality Any earnest belief in star/birth signs and horoscopes cannot survive seeing the actual sky during totality on April 8. In Western astrology, astrological signs consist of 12 constellations, each 30 degrees. All star signs are signs of the zodiac—constellations on the ecliptic , a line in the sky that the sun appears to follow. Where the sun was when you were born is your star sign. If you were born on April 8, you’re an Aries. According to Western astrology, everyone born between March 21 and April 19 is an Aries. Look at the stars during totality on April 8, and you’ll see that the sun will be not in Aries but in Pisces. It’s supposed that if you’re born between February 19 and March 20, you’re a Pisces, but the sun is within that constellation’s boundaries between March 11 and April 18. Western astrology is mainly about convenience, not accuracy, but a month out ? It mostly means that people are not the star sign they think they are—they’re the one that comes before. Western astrology no longer relates to what’s happening in the sky, which is odd given that it concerns the relationships between constellations, stars and planets. Still, there’s a fascinating astronomical reason for that— precession . Earth’s Precession Explained There’s no need to get too judgemental about astrology. It is, after all, at the root of modern astronomy, albeit centuries ago. The Babylonians, living 2,500 years ago in
Iraq and
Syria, first divided the sky into the zodiac. Since then, Earth has precessed . Precession is a natural process lasting 25,800 years that sees Earth wobble on its axis—rather like a spinning top—because of the moon’s gravitational influence. The result is that the “North Star” and the equinox points constantly change. In short, the apparent positions of the stars have shifted west.
