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 ...

Jupiter may have once been more than twice its current size, with a magnetic field 50 times stronger, say scientists who ...
