Although Saturn can be seen with the naked eye, its rings are invisible without a telescope. Galileo was the first to spot them. That was in 1610.
And there are 7 creatively named rings. They span up to about 175,000 miles wide. That is roughly 3/4 of the distance between the Earth and the Moon.
The gigantic rings are super thin, though. And some are just 30 feet high.
The rings look continuous. But they aren't. They're made of billions of particles, from dust-sized frozen grains to much larger pieces of water ice and rocky particles wrapped in ice. The frozen grains whirl around Saturn in different orbits.
We don't know how the rings formed or when. It could have been as early as when Saturn came to be. Or as late as when dinos roamed the Earth.
But we do know that the rings aren't static. Their formation is a continuous process.
Thanks to tech like the probes we've been sending to Saturn since the late 1970s, we're making new discoveries all the time.
We're even identifying new rings. A 7.4-million-mile-wide behemoth was discovered in 2009.
And that's just one of the many reasons why you've gotta love science.
