Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Well, the verdict is in. The Moon is not made of green cheese after all. A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, a solid ball with a density ...

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 ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Scientists who just months ago confirmed that Earth's inner core recently reversed its spin have a new revelation about our planet's deepest secrets — they identified changes to the inner core's shape ...

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 ...
