Science on Tap: The Evolution of Galaxies, with Greg Rudnick

"Greg Rudnick, associate professor of physics and astronomy How do astronomers study galaxies billions of light years away and billions of years in the past? Greg Rudnick will take us to a galaxy far, far away -- or a few of them -- for a talk about what a galaxy is, how we scientists observe them, and how we can indirectly study their evolution, even though the scale of time is far beyond a human lifetime."
