Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...
Most planets have a magnetic field, like Earth, but with different strength or structure. It shields the planet from the energetic particles of the solar wind. The origin of the magnetic field is ...
The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields. Astrophysicists have long puzzled over these surprisingly strong and long-lived ...
More than 50 years ago, NASA landed humans on the Moon — and we brought a piece of it back with us to Earth. That 22 kilograms of rock and dust collected by the Apollo astronauts transformed our ...
The Earth's global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and ...
