The common belief is that buoyancy-driven convection, together with Earth's rotation, is responsible for this geodynamo. However, the role played by precession in the formation of Earth's magnetic ...

All shook up A strange planet with erratic, rapidly changing seasons has been discovered orbiting two stars, by scientists using NASA's planet hunting Kepler space telescope. The planet's strange ...

Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...
