New technique more precisely determines the ages of stars

New technique more precisely determines the ages of stars
How old are each of the stars in our roughly 13-billion-year-old galaxy? A new technique for understanding the star-forming history of the Milky Way in unprecedented detail makes it possible to determine the ages of stars at least two times more precisely than conventional methods, Embry-Riddle Aeronautical University researchers reported Jan. 10 at the American Astronomical Society (AAS) meeting.
