Using computer simulations, the researchers uncovered a scenario in which an ancient asteroid impact briefly amplified that field, just long enough for nearby rocks to capture and record its magnetic ...

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud ...

Over at the Taiyuan Satellite Launch Center in the Shanxi Province, a CZ-6A launched Yaogan 40 Group 02 into polar orbit on ...

A massive impact may have sent a shockwave through the moon, jolting rocks just as a magnetic spike peaked and leaving behind ...

While the moon once had a weak magnetic field generated by a small molten core, the team's research suggests it likely wouldn ...

A combination of a dynamo-generated magnetic field and massive impacts could explain the highly magnetized rocks in some ...

Where did the moon's magnetism go? Scientists have puzzled over this question for decades, ever since orbiting spacecraft ...

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis ...

Two new studies used gravity data to pull back the curtain on the deep interiors of the Moon and one of the solar system’s largest asteroids.

A newly discovered house-size asteroid is set to make a close, yet harmless approach to Earth today (May 21), passing within ...
