And a new study from Beijing, China, published in the journal Nature, was the first to find these waves at this location, where Earth's magnetic field is weak and less uniform. This information could help protect satellites and other spacecraft from damage, since chorus waves can accelerate particles to close to the speed of light. Regina Barber, NPR News.

You're listening to Shortwave from NPR. Hey short wavers, Regina Barber here. I'm going to start today's episode with a question. When I say dinosaur, what do you picture in your head? Maybe a stegosaurus, like a chunky guy with diamond-shaped plates and a ridge along its back. Or a triceratops with like huge horns, kind of like a rhinoceros, but like a little kid had drawn it.

Or a T-Rex, classic, big body, big teeth, tiny little arms. But what you might not think of are feathers. It turns out many dinosaurs did have feathers. We found that out in the mid-90s when dinosaur fossils were discovered at the bottom of a lake in China.

This is Jingmei O'Connor. She's a dinosaur paleobiologist and the associate curator of fossil reptiles at the Field Museum of Chicago. And she says that the structure of a feather is mostly keratin, which is a protein that usually breaks down over time.

For the longest time, I admit, I thought the people at the museums or in the movies were like, taking some creative license. Like, how would they know that all of these dinosaurs had those specific colors, that stripe pattern, these feathers? Because the thing that always threw me off was that some dinosaur displays in the museums had feathers and others didn't have any. Like, what gives?

But of course, they were as accurate as possible. The colors, the patterns, and even which dinosaurs had feathers. Because spoiler alert, not all of them did. So today on the show, the gorgeous, vivid world of dinosaur feathers. Which dinosaurs had feathers? Were they using them to fly? And once and for all, what are ancient dinosaurs' relationship to birds today?
