This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not sound waves. When converted to audio signals, though, these strange ...

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...

Earth's magnetic field results from a swirling sea of electrically charged molten iron in the planet's outer core. Heat currents and Earth's spin both fuel the movement of this liquid iron.

The magnetic north pole, where compass needles point, is about 1,200 miles south and is where geomagnetic field lines are vertical. Earth’s magnetic north is not static. Like an anchorless buoy ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...
