The Sun's core spins nearly four times faster than the Sun's surface according to new findings by an international team of astronomers. Scientists had originally assumed that the Sun was spinning like a merry-go-round with the core rotating at about the same speed as the surface. The researchers studied surface acoustic waves in the Sun's atmosphere, some of which penetrate to the Sun's core, where they interact with gravity waves that have a sloshing motion similar to how water would move in a half-filled tanker truck driving on a curvy mountain road. After the Sun formed, the Solar wind likely slowed the rotation of the outer part of the Sun. It is hoped that eventually, a better understanding of the rotation of the Solar core may give a clue to how the Sun formed.
