For many movie stars, their age is a well-kept secret. In space, the same is true of the actual stars. Like our Sun, most stars look almost the same for most of their lives. Knowing a star's age is important for many astronomical studies and in particular for planet hunters. How can we tell if a star is one billion or 10 billion years old? Soren Meibon will present challenges and possible new solutions to measuring the ages of stars.
The Smithsonian’s Stars Lecture Series is made possible by a grant from NASA.
