Surrounding our planet is a powerful, dynamic invisible force.
Without it, life on Earth as we know it would not be possible.
It is our protective blanket that shields us from the constant bombardment of space
weather.
This is the Magnetosphere, an immense magnetic field that is generated deep within the Earth's
interior, at its core.
It extends out into space, creating a strong protective shield against things such as charged
particles zipping out of the Sun, called the solar wind.
And Without this powerful magnetic field, Earth would likely be a barren, cold, dry
world.
Our red neighbour, Mars is a good example of what happens when a planet, similar to
Earth, loses its global magnetic field.
Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron
that makes up the outer core of Earth around 1800 miles beneath our feet, which is around
2900 kilometres beneath our feet.
Despite being essential to life as we know it, the magnetic field isn’t something we
can actually see or hear in itself.
But we can see its effects on the Earth's atmosphere, in the form of a stunning visual
display called the Aurora Borealis or the Aurora Australis.
And now we can also hear it.
Researchers from the Technical University of Denmark took the magnetic signals, the
radio frequencies measured by the European space agency's Swarm satellite mission and
converted them into sound.
The result is an eerie representation of our planet's rumbling magnetic field and its interaction
with a solar storm.
The audio clip you are about to experience might sound like the stuff of nightmares,
but sit back, relax and listen to the strange creaking, crackling and rumbling of our planet's
protective shield.
This is the sound of the Earth's magnetic field.
What a bizarre sound!
