100 million kilometers from Earth, the most beautiful, enigmatic features of our Solar System.
Saturn's rings were first discovered by Galileo in 1610, using a simple telescope.
Centuries later with sophisticated equipment, the rings of Saturn still look quite simplistic.
But in 1981, when Voyager 1 traveled to the outer planets, the true intricacy of Saturn's rings was revealed.
These images were taken from just 9 million kilometers away.
There are thousands of individual rings orbiting Saturn at different speeds.
Gaps between each one are as wide as 4500km.
The rings may look solid from a distance but each is made up of billions of particles, ranging from the size of a sand grain to the size of a house.
Each particle is traveling faster than a bullet, and they are constantly smashing into each other.
This debris has been identified as pure water ice and rocks.
But just how did it come to be orbiting Saturn?
There are several theories surrounding the formation of Saturn's rings.
Some astronomers believe the debris is simply nebular material - left over from the formation of Saturn itself.
Others believe that Saturn's strong gravitational pull sucked in comets and asteroids over millions of years, trapping them in its orbit.
The most likely explanation for the rings' existence comes from Saturn's many moons.
Close up pictures show that many of them bear the scars of ancient collisions with satellites.
The moon Mimus bears a scar from a collision which very nearly smashed it into tiny pieces.
Prof Carolyn Porco, Lunar and Planetary Lab, Arizona - "If Mimus nearly got bashed up to bits, then it's very likely there were other satellites that did get smashed up to bits. And the rings of Saturn probably came from a satellite that was close in to the planet, got smashed up, the debris or the collisional shards got strewn out, into a planetary ring system."
These theories are our best guess as to how the rings were formed but we are still striving to get closer, in order to unlock the secrets of this amazing phenomenon.
