The mystery of Mars' magnetic field has puzzled scientists for decades. A new study proposes a surprising explanation for its current asymmetry. Researchers at the University of Texas simulated a ...

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 ...

Mercury, Venus, and Mars sit within the same general neighborhood as Earth, yet each has followed a radically different path.

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...

Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered one-half of the planet? This is what a recent study published in Geophysical ...

Launched to Mars in November, NASA’s ESCAPADE probes — operated by UC Berkeley’s Space Sciences Lab — are now testing their ...

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 ...

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 ...
