back to article New FEMTO-MOON sighted BIRTHING from Saturn's RING

Boffins peering at images sent home by NASA's Cassini spacecraft think they may have spotted the first throes of a new moon coming into being. Dubbed “Peggy”, the moonlet is probably a lump of ice. But astroboffin Carl Murray from Queen Mary University of London, lead author of a paper to be published in the journal Icarus, told …

It hasn't even begun.

something is on the move

I predicted this would happen!

After "Chelyabinsk out of nowhere" and "Moon Impact on 9/11", the heavenly signs are quickening.

During victorian times, it would have already been declared British territory, and had a feather hatted governor installed. These days, perhaps Mr Putin will be already planning to protect it's indiginous russian population.

What happened to Peg?

I teleported home one night with Ron and Sid and Peg,

Ron stole Peggie's heart away, and I got Sidney's leg."

(so we now know where the rest of Peg is :) )

(was she cold-hearted?)

(with apologies to Douglas Adams)

Paris, well, she probably has a lot of rings too....

Yeah, but we would have to cut her in half to find out how many.

Orbital mechanics

Ok so start with a large cloud of matter rotating around a gravitational body such as a planet. After a while it tends to settle into a broad disc under the effects of its mutual gravity. Gradually the disc starts to form rings with distinct gaps between them, with small moonlets orbiting at both edges of each ring (what we see here). Eventually the moonlets gather up all of the ring material. What we are left with is a system of moons around the planet.

The Saturn system just has a lot of stuff that hasn't settled into moons yet.

Seems obvious to me?
