New research has identified a new restriction on the chemistry involved in the Earth’s core, explaining how it was able to crystallize millions of years ago. According to this work, the core would ...

While NASA is busy sending astronauts back to the Moon’s surface, other astronomers are trying to figure out what lies beneath that surface. A new study from Université Côte d’Azur, along with ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

This composition resembles models proposed for the inner core. The anisotropy displayed by hcp–Fe–2Si–0.4C at core conditions aligns well with the anisotropy reported by seismic studies for the outer ...

A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

An earthquake originating from Alaska caused seismic waves to penetrate the innermost inner core of the Earth. (Credit: Drew Whitehouse, Son Phạm and Hrvoje Tkalčic) Planet Earth is a marvelous ...

CAPE CANAVERAL, Fla. — Scientists revealed this week 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 ...
