Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to ...

Earth’s magnetic north has just crossed an invisible threshold in the Arctic, slipping into a region that modern navigation ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven by dynamic processes deep within the planet’s core. Drawing on 11 years of ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks ...

Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

In a paper published in Earth and Planetary Physics, a scientific team presents a good correlation between temporal ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...
