A large asteroid, 2003 MH4, will pass by Earth on May 24. It is about the size of the Eiffel Tower. The asteroid will travel ...

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 ...

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

Nasa's Center for Near-Earth Object Studies (CNEOS) and planetary defense teams are vigilantly tracking 2003 MH4’s trajectory ...

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 ...
