Although the magnetic field of Mars hasn't been in effect for billions of years, the evidence it left behind may suggest that the planet's core is entirely liquid. Magnetic imprints still exist on ...

Using data from NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission, scientists identified the Zwan-Wolf effect in ...

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 ...

The sun continuously blasts charged, magnetic field-carrying particles, or plasma, in all directions. This solar wind interacts with the magnetic fields and atmospheres of several of our solar ...

NASA’s MAVEN mission has revealed a phenomenon in Mars’ atmosphere never seen before. Observations captured in December 2023 ...

The InSight lander has now shown there's still more magnetic field activity on Mars than expected -- about 10 times more, in fact. Share on Facebook (opens in a new window) Share on X (opens in a new ...
