It's the moon Ariel, plus maybe a few others. Figured I'd put in comments what the article was about to balance out the name jokes. I used to try and pronounce it with the different accent, but I don't bother now. It's the name.
On the actual topic, that's fascinating that there's enough gravitational force for Uranus to do what Jupiter does to its moons. Granted Ariel is a lot closer. We really need missions for each of these type moons to get under the ice and see what's there.
