A new simulation suggests a massive asteroid impact may have briefly supercharged the moon's magnetic field, leaving behind ...

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

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

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis suggested that in the first billion years, when the Moon was covered in molten ...

Deciphering the universe’s secrets is partly done through observation, but just as important are solid models of the forces ...

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 ...

There should be rocks showing both impact shock and high magnetism located near the lunar South Pole on the far side of the ...

The interstellar medium in our Milky Way galaxy is magnetic, can be compressed, and is turbulent. It affects important ...

Scientists have warned that humanity is not prepared for extreme space weather, as a solar storm is predicted to smash into ...

Space weather forecasting doesn't yet command the same resources as Earth weather forecasting, even though the stakes are growing.

Forecasters of space weather keep an eye on the sun to stay ahead of eruptions of solar material that have the ability to ...
