An international team, led by Instituto de Astrofísica e Ciências do Espaço (IA) researcher Ângela Santos, has made the first ...

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 ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

The robotic spacecraft Psyche has regained propulsion after a snag cut its propellant system in April. Engineers had to ...

A working model of a lunar dynamo, combined with more detailed paleomagnetic analysis of moon rocks, could give scientists a powerful tool for investigating the history of the moon, Dwyer said. In ...

They're neutron stars with a superfluid interior that includes charged particles, so it's easy to understand how a magnetic dynamo is maintained to support that magnetic field.

But the dynamo effect of the Moon’s small core (only about 90 miles [140 km] wide) could produce magnetic fields only one-tenth of that needed to magnetize these large surface regions.

Aug. 5, 2021 — Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots.
