Zodiacal light

And now for something totally different. I have a tendency to accumulate small and obscure interests. I don’t talk a lot about them, since I have long since learned that few people are interested in going in depth on things like Wagner’s Ring Cycle and it’s mythical connections to Tolkien. If you try, you can get me going on some of these at a party, when we have parties again.

Anyway, one of my small obsessions is solar phenomenon. At least, specific solar phenomenon. For the last five or so years I’ve been totally obsessed with the Carrington Event, a Coronal Mass Ejection at the beginning of the industrial age that lit up and partially destroyed the telegraph wires (as well as painting skies across the world with vibrant auroras). I sort of fail to understand why this isn’t a bigger deal. It’s one of the most likely civilization disrupting events (right next to, uh, pandemics). Events of that size hit earth every couple hundred years, depending on a solar cycle much more complex than I realized. (We’re in solar cycle 25 right now, although it seems clear there is also a meta-cycle that lasts longer than our scientific observations and is hard to map to any permanent stuff here on earth.)

Anyway, I decided this summer to dig deeper into the aurora and the coronal mass ejection (and also Northwest Lookout towers) and read this great book called “The Sun Kings: The Unexpected Tragedy of Richard Carrington and the Tale of How Modern Astronomy Began” by Stuart Clark. Towards the end of it, after the unseemly death of the title character (Clark seemed to hate telling that part, but dutifully dished up the promised salaciousness), you get some lovelorn English gents wandering to Egypt with the expected malaria, ill health, and bad neighborliness. They go to investigate the Zodiacal light. Given my obsession with all the other weird phenomenon, I couldn’t believe I had missed one. The Zodiacal lights are a pyramid shaped column of light seen at dawn and dusk roughly between the tropics. And those ill-fated Englishmen (did they die of dysentery/malaria? I don’t recall, but it seems right) couldn’t figure it out. In fact, the mystery stretched down to my reading of the book.

There was a pyramid of light in the sky, and no one knew why.

Until last week.

We launched a probe, Juno, a decade ago. And with it’s vast solar panels, it discovered something in space – a vast section of dust fiercely pinged and pitted the light-catchers. And that dust lined up perfectly with both the trajectory of Mars, and the Zodiacal lights. That pillar in the sky? Mars dust. So cool. Of course, in the manner of all scientific discoveries the answer to one question simply raises another: how did all that dust get into space in the first place? Interesting, but not quite as cool as the mysterious pillar of light in the sky.

Anyway, Zodiacal light has been on my mind this week, so I decided to make this, ahem, artist’s rendition of it. It’s SO CLOSE to what I wanted, without quite being perfect. Ah, the life of a person attempting to make art. Anyway, this picture is definitely an exaggeration. But I got these pearlescent watercolors, and they seemed just right for this dim and misty light. And pyramids are fun. If I’d had skills I would’ve added a camel. But I don’t have skills. I did add two zodiacal signs to either side of the pillar – can you spot or identify them?

What bizarre stuff are you interested in?
