Guest Speaker: Andrealuna Pizzetti, Ph.D. Candidate, Clemson University.
Summary:  Along with being a Ph.D. candidate, Andrealuna is a long-time member of iTelescope and shows several images she has taken with iTelescope scopes.  This is the first of two talks given by Andrealuna.  She begins this talk by looking at the Earth and our sun. She then compares the evolution of our sun to that of other stars.  She also describes and shows images of star-forming regions.  Ms. Pizzetti then describes three types of black holes; stellar mass, intermediate mass, and supermassive black holes, and what it takes to form these.

If you are interested in how stars and black holes form and behave, this video will help you better understand these objects.  We hope you enjoy it!
