Since the 17th century, when Saturn's dazzling, complex ring system was first observed by the Italian astronomer Galileo Galilei, the planet has stood as a symbol of the majesty, mystery, and order of the physical universe.
Although Galileo was the first to see Saturn's rings (in 1610) it wasn't until 1659 that the Dutch astronomer Christiaan Huygens, using an improved telescope, observed that the rings actually are separate from the planet.

 Voyager - Science - Planetary Voyage - Saturn
Voyager 1 found that about 7 percent of the volume of Saturn's upper atmosphere is helium (compared with 11 percent of Jupiter's atmosphere), while almost all the rest is hydrogen.
Since Saturn's internal helium abundance was expected to be the same as Jupiter's and the Sun's, the lower abundance of helium in the upper atmosphere may imply that the heavier helium may be slowly sinking through Saturn's hydrogen; that might explain the excess heat that Saturn radiates over energy it receives from the Sun.
While Voyager 2 was behind Saturn, its radio beam penetrated the upper atmosphere, and measured temperature and density.

Saturn's rings were first seen by Galileo, but were identified as a ring system by Huygens in 1656.
