Kamuela, Hawaii -- As astronomers increasingly link two telescopes as interferometers to reveal greater detail of distant stars, a Keck Observatory astronomer is showing the power of linking three or even more telescopes together. Astronomer Sam Ragland used Arizona's Infrared-Optical Telescope Array (IOTA) of three linked telescopes to obtain unprecedented detail of old red giant stars that represent the eventual fate of the Sun. Surprisingly, he found that nearly a third of the red giants...
