Among the ringed gas giant planet Saturn's amazing collection of 62 diverse, bizarre, and beautiful moons and moonlets, sometimes one of them just seems to stand out in the crowd. Such a moon is little Methone. Looking like a shiny white egg in Space, and composed of very lightweight fluffy stuff, Methone is less dense than any other known moon or asteroid in our Solar System. In March 2013, astronomers announced at the 44th Lunar and Planetary Science Conference held in the Woodlands, Texas, that this strange little 5-kilometer-size moon is one of a batch of Space eggs in orbit around Saturn!
The existence of such powerful roaring winds kicking up violent and powerful dust storms suggests that the underlying sand can be set in motion, too, and that the giant dunes covering Titan's equatorial regions are still active and continually changing.
Comets are actually bright, streaking invaders from far, far away that carry within their mysterious, frozen hearts the most pristine of primordial ingredients that contributed to the formation of our Solar System about 4.6 billion years ago. This primeval mix of frozen material has been preserved in the pristine "deep-freeze" of our Solar System's darkest, most distant domains. Comets are brilliant and breathtaking spectacles that for decades were too dismissively called "dirty snowballs" or "icy dirt balls", depending on the particular astronomer's point of view. These frozen alien objects zip into the inner Solar System, where our planet is situated, from their distant home beyond Neptune. It is generally thought that by acquiring an understanding of the ingredients that make up these ephemeral, fragile celestial objects, a scientific understanding of the mysterious ingredients that contributed to the precious recipe that cooked up our Solar System can be made.
