Sure, we're all star stuff, but exactly how did star stuff come to be? Join Dr. James Lochner as we explore how the cosmic origins of the chemical elements that make up life reflect a variety of events that take place in the universe at the next Space Chats on Friday, November 14 at 7:30 p.m. at the Goddard Visisitor Center. Lochner will trace their origins from the big bang, stellar evolution, supernovae and cosmic rays. He will discuss these processes of element formation, their effect on chemical composition of the universe, and how we determine the composition of the Universe. We'll see how our existence is connected to these elements and to their cosmic origin.

Dr. Lochner is an astrophysicist with Universities Space Research Association working in the Laboratory for High Energy Astrophysics at NASA/Goddard. He directs the education program for the that Lab, and gives numerous educator workshops throughout the year.
