The Gas Giants Jupiter and Saturn are the largest planets in the Solar

System. Internally they are deep, heavy Hydrogen/Helium atmospheres on

top of dense rock/ice cores without solid surfaces. What we see in our

telescopes are just the tops of the clouds. This lecture describes the

basic properties of the planets: their composition, atmospheres,

weather, and internal structures. Recorded 2007 Nov 14 in 1000
