The Earth’s magnetic field is considered vital for life, or at least any life more advanced than bacteria. Similar fields are one of the major things we look for when seeking habitable planets ...

Earth’s magnetic field originates from the motion of liquid iron in its outer core. This flowing molten iron produces electric currents, which are oriented in particular directions as a result ...

Geophysics models explain that, since the movement of a liquid metal induces electrical currents, and currents induce a magnetic field, convection and rotation produce our planet’s magnetic fields.

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

Earth is expected to spin faster than usual in the upcoming weeks, leading to slightly shorter days, scientists report, ...

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface habitability.

Narrett and associates took a different approach and assumed the Moon once had a dynamo that produced a weak lunar magnetic field. Given the size of the Moon's core, they estimated that such a field ...

Every year, billions of birds migrate in and out of the United States. And across the world, birds fly thousands of miles to reach their seasonal destinations. Some birds, like the Arctic tern ( ...
