It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

Geologists use the discipline of paleomagnetism to measure the Earth's magnetic field as it existed millions of years ago. When molten rock cools, magnetic minerals align with the planet's magnetic ...

NASA proclaimed 2024 to be “Heliophysics Big Year,” and with good reason. Heliophysics is the study of the sun, and 2024 gave ...

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon.

Scientists suspected the ice giant hosted auroras—and had already observed them on Jupiter, Saturn and Uranus. But an ...

If the tapestry of President Donald Trump's egregious lies continues to shape policy, democracy itself is in danger.

The study, published in the journal Physical Review Research, builds on work the team conducted back in 2016 and an idea ...

According to scientists, this ambipolar electric field is thought to be just as crucial to Earth as both gravity and ...

The sun is in its solar maximum phase and the Earth is pointed in just the right direction to make the northern lights more ...

Chinook salmon start their lives high upstream in the rivers of western North America. The young fish linger in the safety of freshwater until they are big enough to head out into the open ocean, ...

You may have noticed the large painted numbers (or alphanumeric in some cases) on either end of the runways. Have you ever ...

A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...
