Discoveries of active volcanoes (March 9th, 1979).

Discovered the Jovian ring system and Jupiter's two moons: Thebe and Metis. 

The Great Red Spot is considered a huge cyclone-like storm.

Ganymede has grooved terrain. 

Discovered that Jupiter has lightning. 

It was discovered that Io, Jupiter's moon, has its ion stripped from its surface and it gathers around Jupiter creating Jupiter's magnetic field to inflate.

Took the first pictures of Jupiter's ring system.

Discovered a third moon: Adrastrea.

Getting closer to the moon Europa, shows linear features that may suggest cracks in ice a liquid water ocean. 

Also observed that 6 of Io's volcanoes are still erupting from when Voyager 1 was there. (Their active periods can last for months. Io's volcanoes can also turn on and off.)

Reaches the largest moon, Titan and Saturn itself. 

Discovered three moons: Atlas, Prometheus, and Pandora. Finding Prometheus and Pandora near Saturn's F rind proved scientists' theory of sheepherding moons to keep narrower rings material in line. 

Discovered ghostly features in Saturn's rings. 

Data was gathered from the moon Titan, showing a thick, Earth-like atmosphere.

Voyager 1 begins its voyage out of the solar system.

Encounters most of Saturn's icy moons (Tethys and Iapetus) including the moons that Voyager 1 had discovered. 

Took pictures of the half-young, half-old terrain of the moon Enceladus. 

Took pictures of Saturn's north pole (it will later be found out that there is a hexagonal-shape weather pattern that circulates around the pole).

This is the first time that Uranus was seen up close. 

Also reveals 11 new moons: Puck, Juliet, Portia, Cressida, Desdemona, Rosalind, Belinda, Perdita, Cordelia, Ophelia, and Bianca.

The moon Miranda shows that it may have experienced heating periods from the other moons. 

Uranus's magnetic field is tilted (its magnetic field poles are closer to the equator). 

First to be able to take photos of Uranus's dark rings that reach a temperature of minus 353 degrees, this makes Uranus the coldest planet that we have in our solar system.

Voyager 2 is the first spacecraft to observe Neptune up close. Also, the first spacecraft to visit four planets beyond Earth. 

Discovered 6 new moons: Despina, Galatea, Larissa, Proteus, Naiad, and Thalassa.

Took the first pictures of Neptune's rings.

Discovered a huge storm that is rotating counter-clockwise that is located in Neptune's southern hemisphere. Named "the Great Dark Spot".

First close-up views of the moon Triton. It was a cold, fractured moon with terrain that has a texture of a cantaloupe rind, has geysers that were erupting from pink nitrogen ice. 

Voyager 2 begins its trip out of our solar system.
