Jupiter’s volcanic moon Io emits strange radio waves, NASA’s Juno probe listens

that of NASA The Juno spacecraft “listens” to radio broadcasts from Jupiter’s volcanic moon Io, allowing researchers to find out what sets off the strange radio waves.

Of all the planets in our solar system, Jupiter has the largest and most powerful magnetic field, which stretches so far that some of the planet’s moons rotate within it. Because Io is closest to the planet, the moon is “caught in a gravitational tug-of-war” between Jupiter and two other large moons, according to NASA. These opposing pulls cause massive internal heat, which has led to hundreds of volcanic eruptions on the moon’s surface.
