The mystery of Mars' magnetic field has puzzled scientists for decades. A new study proposes a surprising explanation for its ...

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

Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic ...

Mars' magnetic mystery may finally have a solution—scientists now think the Red Planet’s ancient magnetic field only existed ...

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 ...

Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered ...

Yan said that the one-sided magnetic field could arise if Mars' inner core was liquid. In the study, published in the journal Geophysical Research Letters, the researchers used a computer simulation ...

What were its most important findings? We made the first viable model of the internal structure of Mars—including that the core of Mars is probably still fluid. Another experiment found signs of ...

The three stages the researchers think the core of Mars underwent 4 billion years ago. Only during the early stage of separation would there have been an appreciable magnetic field.

Researchers use the sophisticated technology on NASA's Perseverance rover to analyze volcanic rocks in Mars' Jezero Crater. Their findings show that some of the same volcanic processes that led to ...

Resarchers, including Dr. Michael Tice at Texas A&M University, use the sophisticated technology on NASA's Perseverance rover ...
