Earth is singing to space, and its song sounds a bit like sonar.

NASA on Monday announced the release of what it said was the clearest recording yet of “chorus,” the audio version of the radio signals emitted by the plasma waves in our planet’s Van Allen radiation belts.

“This is what the radiation belts would sound like to a human being if we had radio antennas for ears,” said Craig Kletzing, a physics professor at the University of Iowa, who was in charge of the team that built the NASA instrument that recorded the sound, in a NASA press release.
