Timeline of September NASA Rumor

This is a short timeline that I attempted to put together in order to explain the sequence of how the September 2016 NASA rumor came out:

• Last big zodiac controversy happens in January of 2011.
• January 13, 2016 – Short astrology page updated on NASA education blog
  • The original article was shorter, and written a few years earlier.
  • The article doesn’t say anything about NASA changing the signs.
• January 20, 2016 – High school newspaper blog notes article, but doesn’t gain traction
• September 2, 2016 – Spirit Science blog publishes original sponsored click-bait post.
  • “Your Astrological Sign Has Shifted: NASA Updated The Zodiac Signs For The First Time In 2,000 Years”
  • Article makes it seem like NASA itself has recently changed the signs.
• September 3–4+, 2016 – Spirit Science post gets shared widely on Facebook
• September 12–17 – Story picked up, esp. by women’s magazine sites in second week.
  • September 15 – Cosmopolitan runs a story on it.
  • September 16 – Glamour posts article on it.
  • September 16 – Gizmodo gets statement from NASA.
• September 20/21 – NASA issues updated article/statement on Tumblr blog
  • BBC runs story talking about how the NASA story spread September 21.
• September 22-26 – Coverage from local news networks + lots of other sites.
  • NPR runs story on zodiac issue on September 25.

Zodiac Issue

• The three “zodiacs”: constellational, sidereal, tropical.
  • Only the tropical and sidereal zodiacs are typically used in practice as reference systems.
  • Tropical zodiac aligned with equinoxes and solstices, sidereal with constellations.
• Zodiac standardized to 12 signs of 30 degrees each around 5th century BCE.
  • Around the same time natal astrology was developed.
• Most of the qualities associated with the signs didn’t come about until 1st century BCE.
• Tropical and sidereal zodiacs roughly aligned then.
• Some qualities taken from the tropical zodiac, some from sidereal.
  • Part of the misconception is the assumption that all of the qualities that astrologers associated with the signs are derived from the constellations, which is not true.
• Precession – slow drift apart – 1 degree every 72 years.
• Tropical zodiac already used by Hipparchus in the 2nd century BCE.
• Ptolemy firmly establishes tropical zodiac for western astrologers in 2nd century CE.
• Western astrologers largely using tropical zodiac since 2nd century.
• Sun-sign columns developed in 1930s predicated on tropical zodiac.
• To the extent that western astrology has been predicated on the tropical zodiac for 1800 years now, nothing has changed.
