Saturn and its moons could reveal information since our Solar system birth

Analysis of the data transmitted from the Cassini spacecraft suggests that the moons of Saturn and Saturn’s rings store information from around the birth of our Solar system, NASA suggests.

Those planetary bodies go back more than 4 billion years when the Solar system and the rest of the planets were formed. Studying them could give information about the physical and chemical evolution of our solar system.

Using the Infrared spectrometer of Cassini they have revealed water ice which shows the possibility of the existence of more organic material. The large amount of water ice detected suggests that it must have been from the birth of our solar system since Saturn orbits beyond the ‘frost line’. Inside the ‘snow line’ ice can be formed but outside the frost line it cannot.
