We’ve just discovered the Earth’s largest drum: our planet’s magnetosphere

It’s larger than the Earth itself.

For the first time, scientists directly observe how Northern Lights are formed

How Earth sounds like from outer space

Surrounding our planet areĀ rings of plasma, part of Earth’s magnetosphere, which are pulsing with radio waves.

Recently, NASA scientists recorded some of the Earth’s pulses and transformed them into acoustic waves – the end result is a short song chanted by our very planet.
