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

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

There have been proposed hypotheses as to how the Moon could have developed a core dynamo. For instance, a 2022 analysis ...

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

Asteroid 2003 MH4, a large space rock, will make a close approach to Earth on May 24, 2025. While not an immediate threat, ...

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 ...

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 ...

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

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

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