Hear the eerie sounds of a photo voltaic storm battering Earth’s magnetic discipline

Put the horror films and video games apart for a couple of minutes to hearken to one thing actually disturbing this Halloween season. The European House Company launched audio of what our planet’s magnetic discipline appears like. Whereas it shields us from cosmic radiation and charged particles from the photo voltaic wind, it seems that the magnetic discipline has a disturbing hum.

You’ll be able to’t precisely level a microphone on the sky and listen to the magnetic discipline (and we won’t see it). Scientists from the Technical College of Denmark transformed information collected by the three ESA Swarm satellites right into a sound representing each the magnetic discipline and the photo voltaic storm.

The ethereal sound jogs my memory of wood wind chimes that rattle when a mass of earth shifts, maybe throughout an earthquake. It additionally resembles the crackle of a shifting glacier. You may get one thing totally different out of a five-minute clip.

“The group used information from ESA’s Swarm satellites, in addition to different sources, and used these magnetic alerts to govern and management the sound mapping of the primary discipline. The undertaking was undoubtedly a rewarding train in bringing artwork and science collectively,” stated the college’s Klaus Nielsen, a musician and undertaking supporter. “The hum of the Earth’s magnetic discipline is accompanied by a picture of the geomagnetic storm that resulted from the photo voltaic flare on November 3, 2011, and it is actually sounds fairly scary.”

Should you occur to be in Solbjerg Sq. in Copenhagen this week, you would possibly be capable of immerse your self within the quiet hum of a magnetic discipline. There are greater than 30 audio system directed into the bottom. They’ll broadcast audio 3 times a day till October 30. “We set it up so that every speaker represents a distinct location on Earth and demonstrates how our magnetic discipline has fluctuated during the last 100,000 years,” Nielsen stated.

This is not the primary time researchers have turned information from silent forces into sound. Final yr, NASA launched an audio illustration exercise of the magnetic discipline round Jupiter’s moon Ganymede. Most not too long ago, we heard an eerie rendering of what a black gap appears like.
