Terry Nazon’s Astronomy: Just Plain Wrong


Introduction

I wanted to take a brief pause from writing lectures for the intro astronomy class I’m teaching (don’t worry guys, the one for tomorrow is already written!) and head down a different path for a few moments.

Some may consider me a glutton for punishment. Considering my recent run-in of being threatened by an astrologer, I’ve been following her a bit on Twitter to see what she’s up to in her astrological prognostications. And that’s what I want to talk about today.

Get Your Astronomy Right!

Alright, I’ll say it to start off with to let everyone know where I stand: I do not “believe” in astrology. I trust the studies that have shown it no better than random guessing and that have shown it has no predictive power better than cold reading and self-reporting positive results for positive predictions. I don’t see any mechanism by which it could work, and none that have been proposed by astrologers actually have any physical validity unless they want to re-write the laws of physics.

That said, if you’re going to be an astrologer, AT LEAST GET YOUR ASTRONOMY RIGHT!!!

I honestly don’t know if this is common to most astrologers, or if it just happens to be Terry Nazon who is, well, I’ll be polite and just say apparently ignorant of astronomy and where stuff is in the sky. It’s a little hard to believe considering that astrology’s entire foundation is based on where stuff is in the sky, but, well, facts are facts.

I showed in my series on Nazon before (part 1, part 2, and part 3) that she is apparently fairly ignorant of where objects are in the actual sky, and this is seriously not a case where you just have to take my word for it. Go download any free astronomy sky-display software, look at a star chart yourself, or download a commercial or shareware software. You will be able to demonstrably see that what I stated in my previous series is accurate. (I’m not going to provide star charts this time unless asked for in Comments because I think it’s fairly redundant at this point … and because I need to write a homework set to hand out for tomorrow.)

What’s Going on This Time?

14 hours ago from the time of this writing, so I guess around 6AM MDT (mountain daylight time for those not in the US), Nazon tweeted, “Mercury enters Gemini it’s home placement. Expects things to start moving quickly….”

This intrigued me. I don’t know anything about Mercury’s “home placement,” but based on my experience on my previous series about Terry Nazon (part 1, part 2, and part 3), I wanted to check this. I was not disappointed. At the moment, Mercury is on the Aries side of Taurus, actually having just entered Taurus on June 5 (5 days ago as of writing this). It won’t be until very late in the day on June 25 (that’s in 15 days) that Mercury will enter Gemini. Interesting.

On Monday, so about 2 days ago, Nazon tweeted (and put on her Facebook page): “Mars the planet of action enters Virgo where it last transitied [sic] July 2008. Mars transit around the zodiac is about 2 1/2 yrs. The last time Mars was in Virgo Saturn had just begun it’s transit of Virgo too. Now the two meet up again as Saturn ends its transit through Virgo.”

Also interesting. I love conjunctions, they’re actually really cool to photograph. I showed a conjunction to my class yesterday of the five planets that the ancient civilizations knew about in a photo taken a few years ago. But anyway, back to the claim. I took a look, and yet again, Mars is not anywhere near Virgo. It’s on the Cancer side of Leo right now, though Virgo is on the other side, and Saturn is currently reasonably close to the Leo side of Virgo.

However, Mars moves through the sky much more slowly than Mercury. As a consequence, while Terry Nazon was about 2 weeks off for her Mercury prediction, she’s a full 40 days of for her Mars prognostication. Mars will not enter Virgo until July 19 (actually July 20 for about 1/3 of the world).

(As a side note, about a month later on August 12 there is a VERY cool conjunction between Mars, Venus, Saturn, a thin crescent moon, AND Mercury that will be visible early in the morning evening.)

About the other part of that claim — when Mars last transited (moved through) Virgo, it did so between August 8, 2008, and October 15, 2008. It started doing this reasonably close to Saturn, though that’s almost due to definition: Saturn’s orbit around the sun takes about 30 Earth years. From 1 Earth year to the next, or even 2 Earth years to the next two, Saturn is not going to move very far in the sky. So if Mars right now is near Saturn, then the last time Mars was in this location, it was also near Saturn. But, regardless, Nazon is yet again wrong on her dates.

Final Thoughts

Perhaps I’m picking on low-hanging fruit. But this really does bug me a fair bit. In a different way than all the 2012 doomsday-sayers and young-Earth creationists. Astrologers claim that what they are doing is science. They base what they do on the motions of the planets, sun, moon, stars, and sometimes asteroids. The very least they could do is to get those motions and positions correct!

And yet again, I’ll use the refrain: If Nazon’s easy-to-see astronomy claims of where objects are when are so demonstrably wrong (and other astrologers who may be wrong like her), why should ANYONE pay the $75 an e-mail or up to $330 an hour for one of her “readings?” Heck, send me an e-mail and I’ll at least tell you where stuff is in the sky when. And I won’t charge you nearly that much.
