(no subject)

I have a paid account on IJ for some of my roleplaying characters. I think I bought it last Thanksgiving. Annoyingly, the Black Friday sale means I either need to let it go a few days as unpaid, or buy knowing the sale will be in a week or two. Or work out the logistics of paying for a short time, then renewing for the sale.

(Mostly I use it for the icons, I'll be honest. Hell, I don't even think I need that many icons, since I don't use them all, but...)

Timing, Eris and Saturn's Moons

Every other week, my research group and a few interested bystanders have a Distant Planets Journal Club. Recently, a book called Saturn from Cassini was published that aimed to collect a summary of everything we have discovered about Saturn, its rings, and its moons (except Titan, which got its own book) since Cassini arrived there. This week, we read the chapter on the origin of the Saturnian system, which was mostly about its moons*.

It's interesting, since the professors in the group have worked on outer planets since Voyager was doing its thing, so they have a good sense of the history of the field. So we talked a bit about how more data messes up the nice, simple pictures we make.
