A new study gives potential insights into how the Red Planet's magnetic field, which protected its atmosphere, faded away.
might have led to the planet losing its magnetic field early in its history, a new study suggests.
In particular, researchers want to understand what might have caused the planet's protective atmosphere to dramatically thin. Now, a new study examines changes in the planet's core that may have led to the magnetic field of Mars weakening over time, leaving the atmosphere vulnerable to erosion.
Using X-ray and electron beam observations, the team followed the changes in the sample as the material was being pressurized and compressed. The scientists discovered the initially homogenous Martian material separated into two liquids. On Mars, however, the magnetic field only lasted temporarily. After the liquids separated, the study suggests, the currents ceased since there was no more activity to drive the currents. solar wind
