Sunspots Reveal Rotation of Stars Across Space
Newhouse News Service reports astronomers use starspots to measure stellar rotation. Mount Wilson team, using ultraviolet light variations, determine rotation for 28 of 54 sun-like stars within 100 light-years. Findings suggest the sun's magnetic field arises from its own rotation and aim to explain the sunspot cycle.
