New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years.

The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small ...

New simulations show carbon enabled Earth’s inner core to solidify under realistic cooling, solving the nucleation paradox.

Weak magnetic fields once exposed humans to radiation. People adapted with shelter, clothing, and mineral protection. Our ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a ...

Eventually, the blob of molten material beneath Canada split in two and the stronger one slowly shifted toward the blob ...

Where did the Moon's magnetism go? For decades, scientists have been puzzled by this question, which has lingered since orbiters detected signs of high magnetic fields in lunar surface rocks. Today, ...

Mars is known for its barren desert landscape and dry climate. But two recent studies in the journals Nature and Science go ...

Using data from NASA’s retired InSight lander, two separate teams of researchers found evidence of a sluggish Martian mantle ...

A synthetic cell that can be activated by a magnetic field to release a medicine while deep in the body has been created by ...
