Giant magnetic wave found in Earth’s core

Volcanic eruptions remind us that the inside of our planet isn’t exactly tranquil, but there’s plenty of completely unknown stuff happening beneath our feet.

ESA’s Swarm satellite mission has detected a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years.

The finding could help us to understand more about Earth’s magnetic field, without which life as we know it could not exist.
