Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms.

The moon may be silent and still today, but billions of years ago, it likely crackled with magnetic activity. Though the moon now lacks a global magnetic field, its rocks—especially those on the ...

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 ...

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 research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...

"Evidence of strong early magnetic field around Earth." ScienceDaily. ScienceDaily, 21 January 2020. <www.sciencedaily.com / releases / 2020 / 01 / 200121113046.htm>.

The question of how the Moon’s core could produce a strong magnetic field remained unsolved. Samples from the Moon, ... We found that nearly all the rocks had profoundly weak magnetic signals.

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

They propose that a combination of an ancient, weak magnetic field and a large, plasma-generating impact may have temporarily created a strong magnetic field, concentrated on the far side of the moon.

The group’s calculations showed that magnetic fields can be generated about 20,000 miles (32,100 kilometers) below the sun’s surface — far closer to the surface than had previously been assumed.

The moon may be silent and still today, but billions of years ago, it likely crackled with magnetic activity. Though the moon now lacks a global magnetic field, its rocks—especially those on the ...
