Galaxies! Images of these objects are awe-inspiring - spirals of billions of stars, along with the gas and dust from which stars form, spinning slowly in the sky. Yet these majestic objects are thought to have formed quite violently through the agglomeration of smaller objects. Even our own home - the Milky Way galaxy - seems to be in the process of devouring several smaller galaxies!
Dr. Kathryn V Johnston, Professor of Astronomy at Columbia University, will examine why we think galaxies are cannibals in general, and what this means about the past and future evolution of the Milky Way in particular.
This talk is co-sponsored by the Astronomical Society of Greenwich. It is free and open to the public. Registration is required.
