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

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

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

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 ...

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

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 ...

The asteroid will pass at a distance of 6.68 million kilometres from Earth, which is roughly 17 times closer than the distance between Earth and the Moon. Astronomers consider such proximity a close ...

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

A house-sized asteroid flew past Earth while you were asleep. The space rock designated 2025 KF made its closest approach at ...

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

Just days earlier, on May 21, a smaller asteroid named 2025 KF made an even closer pass — just 111,000 kilometres from Earth, ...

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 ...
