Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

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 ...

Image of the Sun taken from the Solar Dynamics Observatory satellite, showing the quiet corona and magnetic structures like coronal loops, which trace the intricate patterns of magnetic field lines ...

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 ...

New observations from the National Science Foundation National Radio Astronomy Observatory's (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal ...

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 ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

Uranus's mysteriously asymmetrical and skewed magnetic field has long confounded astronomers—until now. When the Voyager 2 spacecraft zipped past Uranus in 1986, it noticed that the huge gas giant's ...

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 ...
