For the first time ever, astronomers may be observing a new moon in the process of forming in the solar system. It’s hard to tell for certain, but a “protuberance” in one of Saturn’s rings looks like it’s coalescing into a half-mile diameter satellite. If so, it would be joining Saturn’s large family of 50+ satellites — most of which are rather small, themselves.

For now, astronomers have dubbed the nascent moon “Peggy.” Personally, I’m old-school — if the bulge turns into a moon, I want it named after something mythological. Or at least geeky (Praxis, anyone?).
