In 1997, NASA launched the Cassini-Huygens spacecraft to explore and photograph the mysterious planet Saturn. And 20 years later, NASA released high-resolution photos of exactly what the unmanned spaceship was able to see.
Researchers at NASA and the European Space Agency teamed up to design Cassini-Huygens in the 1980s. Named after astronomers Giovanni Cassini and Christiaan Huygens, the spacecraft was designed to not only photograph the planet, but also to collect data from it and its 62 moons. These latest photos came from Cassini-Huygens's final phase - called the Grand Finale - which started in April 2017. On September 15, 2017, Cassini's mission came to a close, and it burned up in Saturn's upper atmosphere.
This is a storm off the top of Saturn's north pole. Researchers estimate the storm is 1,250 miles across.
Saturn's moon Enceladus might have an ocean on it, or at least scientists think it might. This image shows geysers around the moon's south pole, with what appear to be ice-water rivers underneath its ice shell.
This photo, captured on April 12, 2017, shows the speck of light Earth appears to be from 870 million miles away. This shot was taken through Saturn's icy A ring and F ring.
Here we can see in color the surface of Saturn, and the shadow its rings cast upon it.
