Caption: An image of the star Regulus, which University of Michigan astronomers and their colleagues were able to "zoom in" on using a technique called interferometry. Zooming in allowed them to measure the temperature of the star's poles separately from its equator, which enabled them to find flaws in a century-old astronomical theory about hot, fast-spinning stars.
