Put horror motion pictures and video games apart for a couple of minutes to hearken to one thing really unsettling this Halloween season. The has launched audio of what our planet’s magnetic area seems like. While it protects us from cosmic radiation and charged particles from photo voltaic winds, it seems that the magnetic area has an unnerving rumble.
You cannot precisely level a microphone on the sky and listen to the magnetic area (nor can we see it). Scientists from the Technical University of Denmark collected by the ESA’s three Swarm satellites into sound, representing each the magnetic area and a photo voltaic storm.
The ethereal audio jogs my memory of wood wind chimes rattling as a mass of land shifts, maybe throughout an earthquake. It brings to thoughts the cracking sounds of a transferring glacier as nicely. You would possibly get one thing totally different out of the five-minute clip.
“The staff used knowledge from ESA’s Swarm satellites, in addition to different sources, and used these magnetic indicators to govern and management a sonic illustration of the core area. The undertaking has actually been a rewarding train in bringing artwork and science collectively,” the university’s Klaus Nielsen, a musician and supporter of the project, said. “The rumbling of Earth’s magnetic field is accompanied by a representation of a geomagnetic storm that resulted from a solar flare on November 3rd, 2011, and indeed it sounds pretty scary.”
If you occur to go to Solbjerg Square in Copenhagen this week, you could possibly immerse your self within the magnetic area’s low rumble. More than 30 loudspeakers are pointed on the floor there. They’ll broadcast the audio thrice day by day till October thirtieth. “We have set it up so that every speaker represents a unique location on Earth and demonstrates how our magnetic area has fluctuated during the last 100,000 years,” Nielsen mentioned.
This is not the primary time researchers have turned knowledge from in any other case silent forces into sound. Last yr, NASA of magnetic area exercise round Jupiter’s moon Ganymede. More lately, we acquired to listen to a terrifying depiction of what a black gap seems like.
