Raja Guhathakurta, of the University of California at Santa Cruz, has a deep passion for advancing astronomy research and education.  A professor in one of America’s finest astronomy programs, Raja makes complex and technical details of the cosmos intimate and understandable with humor, striking images and beautiful computer animations.

In this recorded presentation at Keck Week, Professor Guhathakurta shares his ground breaking research into the nature and evolution of the Andromeda Galaxy, M31, our closest neighbor in the vast expanse of the Universe and explains how studying the “Galaxy Next Door” offers many keys to knowing our own Milky Way home.
