New research published by the University of Texas Institute for Geophysics offers a compelling explanation for the strange ...

A new study suggests this bizarre imbalance could be the result of a molten core and uneven internal heating that generated a powerful, lopsided magnetic field. This flips earlier Earth-like ...

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 ...
