Earth’s magnetic field protects the planet from space weather like cosmic radiation and charged particles from the Sun. The southern Atlantic anomaly shrinks that protective bubble, but not so much ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New ...

Iron, the most abundant element by mass on Earth, reveals a fascinating complexity under extreme conditions of temperature ...

Earth’s trusty magnetic field has been keeping the planet safe for at least 3.7 billion years. There’s a chance it might have formed even earlier than this, but the evidence is shaky and less widely ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Scientists have discovered that Earth’s magnetosphere is charged opposite to what was once believed. The area of space influenced by Earth’s magnetic field is called the magnetosphere. Within this ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.
