On Earth, we can use artifacts and the archaeological record to tell us about historic activity.

In space, we must rely on different methods. 

Keith Hawkins, galactic archaeologist and assistant professor of astronomy at the University of Texas at Austin, is doing just that–using fossil stars to piece together the nature and structure of the Milky Way. In this Frontiers Lecture, Hawkins will discuss his research using multi-object spectroscopic surveys to better understand the chemo-dynamic properties of our galaxy. What can the chemical composition of stars tell us about our galaxy’s formation, its evolution and structure, and its relationship to other galaxies?
