Detailed explanation-1: -Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, Voyager 1 and Voyager 2, flew by Saturn in 1980 and 1981. In 2005, the spacecraft Cassini started multiple close flybys of Enceladus, revealing its surface and environment in greater detail.

Detailed explanation-2: -Prior to its dramatic and intentional crash into Saturn in 2017, the Cassini spacecraft gathered data that suggests Enceladus, one of Saturn’s moons, contains most of the ingredients that are essential to life on Earth.

Detailed explanation-3: -Haze-enshrouded Titan is Saturn’s largest moon and the solar system’s second-largest, and an all-around exceptional place. Titan is the only known world other than Earth where any sort of liquid collects on its surface.

Detailed explanation-4: -Cassini revealed the dramatic truth: Enceladus is an active moon that hides a global ocean of liquid salty water beneath its crust. What’s more, jets of icy particles from that ocean, laced with a brew of water and simple organic chemicals, gush out into space continuously from this fascinating ocean world.

Detailed explanation-5: -Christiaan Huygens discovered the first known moon of Saturn. The year was 1655 and the moon is Titan.
