The unusual origin of Saturn's moons

Saturn's icy moons medium size were twisted when several much larger satellites crash, forming a giant moon Titan, states a new study conducted by a team of scientists led by Eric Asfogom University of California, Santa Cruz.

Initially, in the Saturn system there exists a family of relatively large satellites known as the "Galilean satellites" (Ganymede, Europa, Callisto and Io), according to a new theory. But everything changed after a series of rather large collision between satellites, which are formed by Titan and was thrown into a huge amount of space matter that formed satellites such as Mimas, Enceladus, Tethys, Dione, Rhea and Iapetus, the researchers say.

New observations made ​​by NASA's Cassini, will help astronomers to test the model.
