Good thing The Expanse is a series instead of a movie.

I admire the optimism of everyone who didn't expect this outcome

Imagine not knowing your bearings at all times...

Also imagine not looking like a sailor...

Fair, I messed up the names there. Moonette is the synonym of that that I was thinking of.

But a satellite (natural or artificial) is any object that orbits around a celestial body. The Earth is a satellite just as the Moon is one. Subsatellite is just the satellite of a satellite, but that depends on context. Moons fit that definition, but aren't usually considered subsatellites because we don't usually think of planets as the satellites of the Sun that they are.

A ~~moonlet~~ moonette is a natural satellite of a moon without being a moon itself. A planet is also a natural satellite of a star. The use of the word "moon" as a common term for natural satellites of planets is well established in professional terminology.

True, but it's also the name of the Roman godess, which does make it allign better with all the other astronomical names.

Not refraction, but diffraction and interference. The droplets (or ice particles or in some cases even pollen) get so small that light stops behaving like rays at those scales.

This is the 22° halo. A Corona is an entirely different phenomenon caused by diffraction and interference of light around tiny water or ice particles, or other such particles of similar size. Halos on the other hand are formed by refraction. Here's another great resource about coronae (and pretty much every other atmospheric optical phenomenon out there).

You're correct about halo phenomena being caused by ice crystals. As such, they are most often observed when there's Cirrostratus in the sky, and that in turn is often the result of an incoming warm front. The Cirrostratus may start to thicken into Altostratus and Nimbostratus, so overcast and rainy would be the safest bet.

You are reading about it, so it is at least spreading awareness (not of the problems we all already know exist, but of the fact that there are still people willing to put their necks on the line fighting for a better future).

Originally it said except the chaos, making it even less intelligible.

Reading this gave me a stroke.
