Put horror films and video games apart for a couple of minutes to hearken to one thing actually unsettling this Halloween season. The European House Company has launched audio of what our planet’s magnetic area seems like. Whereas it protects us from cosmic radiation and charged particles from photo voltaic winds, it seems that the magnetic area has an unnerving rumble.
You’ll be able to’t precisely level a microphone on the sky and listen to the magnetic area (nor can we see it). Scientists from the Technical College of Denmark transformed information 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 shifting glacier as properly. You would possibly get one thing totally different out of the five-minute clip.
“The crew used information from ESA’s Swarm satellites, in addition to different sources, and used these magnetic indicators to control and management a sonic illustration of the core area. The undertaking has actually been a rewarding train in bringing artwork and science collectively,” the college’s Klaus Nielsen, a musician and supporter of the undertaking, stated. “The rumbling of Earth’s magnetic area is accompanied by a illustration of a geomagnetic storm that resulted from a photo voltaic flare on November third, 2011, and certainly it sounds fairly scary.”
In the event you occur to go to Solbjerg Sq. in Copenhagen this week, you could possibly immerse your self within the magnetic area’s low rumble. Greater than 30 loudspeakers are pointed on the floor there. They will broadcast the audio 3 times every day till October thirtieth. “We now have set it up so that every speaker represents a special location on Earth and demonstrates how our magnetic area has fluctuated during the last 100,000 years,” Nielsen stated.
This is not the primary time researchers have turned information from in any other case silent forces into sound. Final yr, NASA launched an audio illustration of magnetic area exercise round Jupiter’s moon Ganymede. Extra just lately, we obtained to listen to a terrifying depiction of what a black gap seems like.
