He was the one who discovered the rings around Saturn as well as Titan in 1655; the largest moon of Saturn. He also invented the pendulum clock. He died in 1695 on 8th July.
Jean Dominique Cassini was born in 1625, on June 8th. He has numerous discoveries related to Saturn attached to his name. He discovered four of the Saturn’s moons, Iapetus in1671, Rhea in 1972, Tethys and Dione in 1684. He also discovered that the rings of Saturn have separation by a gap in two parts in 1675, it is in his honor named Cassini Division, and he presumed that the Saturn’s rings composition was of the small particles myriads, which was correct.
The atmospheric entry probe which was part of Cassini–Huygens mission carried to Titan; Saturn’s moon was called the Huygens probe. It separated itself from the spacecraft on 25th December 2004 (Scott Allen Striepe, pg12) and landed on Titan’s surface on 14th January 2005. The landing of this Huygens probe was designed for both water and land since it wasn’t concrete which kind of surface it might be; it turned out to be solid, icy. It sent several images that helped understanding of Titans atmosphere throughout its descent.
The atmosphere of Titan is twice in its thickness compared to that of Earth, the surface pressure there is approximately 1.45 times that of the earth. This makes it hard for image capturing in visible spectrum of light by the astronomical instruments.
Titan is second largest moon in Solar system with diameter of 5,150 km, with the only one having dense, surface pressure being 1.5 atm and cold atmosphere, primary composites being nitrogen and little methane. Being dense, its atmosphere usually has convective clouds that are bright white, making the surface observation difficult. It is also the only moon that has large liquid bodies, in form of lakes of methane.
Composition: Saturn’s rings have sheet like distribution of the icy
