How Saturn Got Its Rings

Within the past 100 million years, an icy moon got too close to Saturn and the planet’s gravity ripped it apart, forming the iconic rings. This clip from BBC’s The Planets details how that happened, accompanied by some amazing photography from NASA’s Cassini mission.

I got this from The Kid Should See This, who shared some ring facts:

They are younger than the dinosaurs, they form a disk wider than Jupiter that averages just 9 meters (30 feet) thick, and thanks to Cassini, we now know that there are tall peaks rising as high as 2.5 kilometers (1.6 miles) from the planet’s B ring.

I’ve shared this story on the site before, but seeing the rings of Saturn through my telescope in my backyard as a teenager made a massive impression on me as to the scale of the solar system and humankind’s ability to understand it through science and technology. I still can’t believe you can see those rings with a cheap telescope or binoculars. Incredible.
