Earth's Inner Core Rotation Slower Than Estimated
intellitech writes "Scientists at the University of Cambridge believe they have achieved the first accurate estimate of how much faster Earth's core is rotating compared to the rest of the planet. The rate — about one degree every million years — is much slower than previously thought and arises from the complex dynamic between Earth's inner and outer core, which generates Earth's geomagnetic field. Without our magnetic field, Earth's surface would not be protected from charged particles spewing from the Sun, and life would not be able to exist."

Venus manages to have an atmosphere 93 times more massive than Earth's while having no intrinsic magnetic field and being subjected to a stronger solar wind.
There is still much we have to learn.
