The Unprecedented Speed of Past Reversals A study by geophysicists from UC Berkeley and their Italian and French colleagues has shed new light on Earth's last major magnetic reversal. Occurring ...

Explaining the science behind the northern lights, and why 2025 could bring more opportunities to see them. #ExtremeNature ...

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 ...

NASA's EZIE will study auroral electrojets, powerful electrical currents in Earth's atmosphere. This will improve space ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

Geomagnetic excursions are short-lived, and involve temporary changes to the Earth’s magnetic field lasting anywhere from a few hundred to a few thousand years. The most recent recorded ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...

Scientists have been wondering about auroral electrojets for a long time. This mission could change how we understand them.

Loggerhead sea turtles ( Caretta caretta) are pretty loyal marine reptiles. Even with their roughly 8,000-mile-long migrations across oceans, they consistently return to the same feeding and nesting ...
