Life-cycle of stars: formation, adulthood, and death - Dr. Marla Geha

Sept 12, 2007 - Life-cycle of stars: formation, adulthood, and death - Dr. Marla Geha, Herzberg Institute

Only a small fraction of the mass in our Milky Way Galaxy is composed of the stars, gas and dust that we can directly observe. The majority of matter in our Galaxy is unseen, making its presence known only through it gravitational force. Dr. Geha will discuss evidence for dark matter and explain a few experimental methods with which astronomers hope to characterize the total mass, distribution and composition of this unseen matter in the Milky Way.
