“The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is usually thought to be shaped like a ball, but its edges may actually have deformed by 100m or more in height in places, according to Prof John Vidale who led the research. Earth’s core is the beating heart of our planet as it produces a magnetic field that protects life from burning up in the Sun’s radiation. The inner core spins independently from the liquid outer core and from the rest of the planet. Without this motion, Earth would die and become more like barren Mars which lost its magnetic field billions of years ago. … The research is published in the scientific journal Nature Geoscience.” (02/10/25)
