Contrary to previous assumptions, the Moon's passage through Earth's magnetic field, or "geotail," does not lead to lower plasma densities. Listen to Story Scientists from the Space Physics Laboratory ...

Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications. Data from NASA's InSight mission has revealed that ...

Recent research from the University of Southern California has focused very closely on the outer core. The fact that this layer is responsible for our magnetic field makes it extremely important and ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...
