In 2020, Andrea Ghez shared the Nobel Prize for her observations of a supermassive compact object at the center of the Milky Way galaxy—an object that has all the hallmarks of a <a href="https://www.sciencefriday.com/segments/milky-way-black-hole-center?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">supermassive black hole</a>. Ghez had developed techniques that allowed her to peer through galactic dust clouds with the Keck telescopes and observe the movements of stars orbiting the galactic center. Measuring their velocity and orbits provided information about the galactic core.
 She joins Host Flora Lichtman to talk about this game-changing discovery, what we’ve learned about the galactic center, and her own orbit in science. 
Guest:
Dr. Andrea Ghez is a Nobel Laureate in Physics (2020) and a professor of physics & astronomy at UCLA.
