By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...
A 2024 study, for example, found that the rotation of Earth's core had slowed down. This new study "introduces a new perspective — non-rotational changes — adding another dimension to the ...
Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...
Recent seismic data from 121 earthquakes recorded over three decades challenges previous beliefs about Earth's inner ... observed while studying the core's slowing rotation, could of ...
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.
STRANDED astronauts Barry Wilmore and Sunita Williams finally made a triumphant splash down on Earth – after being stuck in ...
Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.
