Another sign that Earth has a magnetic field is that a compass points north wherever you are on the planet. But how can we tell if other planets or bodies in the solar system have magnetic fields?

Stars have magnetic fields that initially get stronger as the speed of the star’s rotation increases. There are still aspects ...

Of course, there's Earth's magnetic field, which deflects dangerous cosmic radiation, wiggles our compasses, and guides flocks of migrating birds. But other planets and stars have magnetic fields ...

The magnetic fields of both planets, which are not that far apart in mass, are not dipolar. Earth, Jupiter, and Saturn all have dipolar magnetic fields, meaning they have a north and south pole ...

The hunt for extraterrestrial life is only one reason to wonder about Earth's magnetic field. Not every planet has a magnetosphere, and researchers aren't quite sure what kicked Earth's into gear.

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet. When you purchase ...

Jupiter, roughly 562 million miles from Earth today, has nearly 100 moons. But Batygin and his collaborator Fred Adams' ...

Recent research, however, has proposed a promising answer: the molten Martian core likely generated a magnetic field that only covered the Red Planet’s southern hemisphere. A new study published in ...
