First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

The waves propagate deep within the planet. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A new type of slowly traveling magnetic wave ...

Researchers from the Australian National University (ANU) found evidence of a new layer to Earth within the inner core, according to Engadget. The inner core is an iron-nickel alloy ball that is a ...

Fish, birds, reptiles, amphibians, and even a few mammals rely on magnetoreception for navigation. But the exact mechanism ...

Pigeons may sense Earth’s magnetic field using their inner ear, sending signals to brain areas that help with navigation and memory.

Sometimes there are storms where the wind gets really strong, it might rain, or there might be thunder and lightning. Did you ...

The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades. One explanation is ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
