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 ...

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 ...

The new research adds to the mysteries of the planet’s deepest interior region. By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be ...

The Chinese-led research team based its findings on seismic readings from NASA's InSight lander on Mars, which recorded more than 1,300 marsquakes before shutting down in 2022. The spacecraft landed ...

CAPE CANAVERAL, Fla. (AP) — Scientists revealed Wednesday that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
