Earth, inner core

‘It’s almost science fiction’: Scientists say the shape of Earth’s inner core is changing
Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.
Scientists discover Earth's inner core isn't just slowing down — it's also changing shape
The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.
Scientists say the Earth's inner core maybe changing in shape; know what it means to life
Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic analysis,
Earth’s Mysterious Inner Core Is Changing Shape
Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more
Earth's inner core isn't just slowing, it's also shape-shifting, study finds
USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
Earth's inner core is less solid than previously thought: Study reveals structural transformation
The surface of the Earth's inner core may be changing, as shown by a new study by USC scientists that detected structural changes near the planet's center, published in Nature Geoscience.
