The sound of space is truly strange. The sound of Earth! “It’s called chorus,” explains Craig Kletzing of the University of Iowa. “This is one of the clearest examples we’ve ever heard”. The Researcher explains the sound of Earth. “This is what the radiation belts would sound like to a human being if we had radio antennas for ears,” says Kletzing, whose team at the University of Iowa built the “EMFISIS” (Electric and Magnetic Field Instrument Suite and Integrated Science) receiver used to pick up the signals.
“Chorus emissions are front and center for the Storm Probe mission,” says Kletzing. “They are thought to be one of the most important waves for energizing the electrons that make up the outer radiation belt.”
There is a myth that there is no sound of space, but space is a vacuum — so it usually doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them). But the various probes zooming through our universe are capable of capturing radio emissions from space objects.
The sound of Saturn!
Saturn is a source of intense radio emissions, which have been monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth’s northern and southern lights. This is an audio file of radio emissions from Saturn.
The sound of Jupiter!
NASA’s Jupiter-bound Juno spacecraft has entered the planet’s magnetosphere, where the movement of particles in space is controlled by what’s going on inside Jupiter.
“We’ve just crossed the boundary into Jupiter’s home turf,” said Juno Principal Investigator Scott Bolton of Southwest Research Institute, San Antonio. “We’re closing in fast on the planet itself and already gaining valuable data.”
“If Jupiter’s magnetosphere glowed in visible light, it would be twice the size of the full moon as seen from Earth,” Kurth said. And that’s the shorter dimension of the teardrop-shaped structure; the dimension extending outward behind Jupiter has a length about five times the distance between Earth and the sun”.
