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 ...

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 ...

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

Far from the Sun, Uranus sits tipped on its side, carrying a magnetic system unlike any other planet’s. Its equator tilts ...

The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading ...

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 ...
