Asteroids help scientists to measure the diameters of faraway stars

Using the unique capabilities of telescopes specialized on cosmic gamma rays, scientists have measured the smallest apparent size of a star on the night sky to date. The measurements reveal the diameters of a giant star 2,674 light-years away and of a sun-like star at a distance of 700 light-years.
