The single whistler event was recorded over a crustal magnetic field, at an altitude of 349 kilometers (217 miles) on the ...

While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic ...

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 ...

New research published by the University of Texas Institute for Geophysics offers a compelling explanation for the strange nature of Mars’ ancient magnetic field. The study suggests that the Red ...

Billions of years ago, Mars likely had liquid water, rivers, and a thicker atmosphere. But when its internal magnetic field collapsed, the planet lost its shield against the solar wind, allowing ...

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 ...

NASA’s ESCAPADE mission studies how solar wind removed Mars’ atmosphere, using twin spacecraft to measure atmospheric escape, magnetosphere changes, and space weather impacts.

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 ...
