Delving into the realm of geomagnetism and volcanology, scientists have unearthed a fascinating link between volcanic ash and ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves ...

The early Universe hosted ultra-weak magnetic fields that still shaped cosmic structures. New simulations establish stricter limits on their strength. Magnetic fields that originated during the earlie ...

In other words, the dynamo (the natural process through which the sun produces its magnetic field) that was thought to depend on the tachocline also appears to create and maintain ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...

Every so often—every 250,000 years on average—the Earth's magnetic poles reverse polarity. If such a reversal happened today, compass needles would point south rather than north. Here, view a computer ...

Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum ...

When a sodium-filled model of the Earth’s outer core spins at full speed, it could generate a dynamo. Courtesy Daniel P. Lathrop In a large, warehouse-like laboratory on the University of Maryland ...

The Earth's magnetic field surrounds our planet like an invisible force field—protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is ...

We are in the midst of a new era in space exploration, one in which everyone from NASA to Elon Musk's SpaceX have expressed interest in the idea of sending humans to Mars and even establishing ...
