Little was known about Saturn and its moons before Voyager flew. It has always been assumed that Jupiter, like Saturn, has an atmosphere largely composed of hydrogen and helium.
However, this hypothesis will not be substantiated until Voyager flybys. Voyager spacecraft have revealed that Saturn has a hydrogen-dominated atmosphere with a small amount of helium. While flying to Saturn's largest moon, Titan, it discovered a world completely covered in an extremely dense atmosphere of hydrocarbons. Voyager also found evidence of a hydrocarbon lake in Troyton.
After Saturn, the Voyager 1 spacecraft completed its mission and flew into interstellar space, but Voyager 2 flew very close to Saturn. It was revealed that Voyager 2 was orbiting Saturn's light as it penetrated Saturn's upper atmosphere, directing the spacecraft to study Saturn's spectrum, and Voyager 2's composition of Saturn's atmosphere. Was able to study its temperature. Voyager 2 has revealed that the temperature on Saturn will reach as low as 82 degrees Kelvin. (-312 Fahrenheit) and temperatures near its poles reached as high as 18 degrees Fahrenheit, and the atmosphere was dominated by hydrogen.
very interesting
