All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to ...

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 ...

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

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 ...

There may be more northern lights – or aurora borealis – sightings this spring. As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and solar wind ...

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 ...
