Ground-based observatories such as the 3-meter NASA Infrared Telescope Facility (IRTF) might indeed not be as detailed as Cassini for high-resolution pictures, but when it comes to daily monitoring, they are the ideal instruments. Indeed, Cassini only flies by Titan roughly every two months.

Un océan de diamant sur Uranus et sur Neptune - En quête de scie
Depuis les années 1980 et les travaux de Marivin Ross , on suppute qu'il y a de grandes quantités de carbone pur dans ces planètes – de l'ordre de 11 à 17 % de leur masse . Comme règnent, au cœur de ces planètes des conditions extrêmes de température et de pression, ce carbone pourrait être sous forme de diamant, liquide et solide. Cette dernière étude apporte une pierre de plus à cette théorie.
Iorio also calculated how planetary accretion of dark matter would affect the motion of the planetary satellites but found this to be negligible – with the Moon's orbital radius a mere 160 m greater at the beginning of the solar system.
