The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Observations by ISRO's Aditya L1 mission has helped scientists explain geomagnetic disturbances at dawn during severe space weather events. The observations were conducted during the solar storms of ...

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 ...

For a few brief nights each year, you get a rare chance to watch a monster blink. The Event Horizon Telescope collaboration ...

Magnetic fields thread through galaxies, stretch across cosmic voids, and shape the behavior of charged particles over millions of light-years. Yet their origin remains one of the most stubborn ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

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 ...

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 ...

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 ...
