In its earliest days, Jupiter may have been even more colossal than it is now—twice as large, in fact, with a magnetic field ...

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 ...

Reference See what moon phase it is tonight and find out when you can see the rest of the moon phases for 2025. A new simulation suggests a massive asteroid impact may have briefly supercharged the ...

Discoveries from NASA's GRAIL mission reveal the moon's uneven interior, with a molten layer beneath the near side surface.

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 ...
