Andrea Mia Ghez, PhD, the fourth woman to be awarded the Nobel Prize in Physics, is an American astrophysicist whose research focuses on the center of the Milky Way galaxy. She became interested in science after she watched the first lunar landing on TV and planned to be the first woman astronaut on the moon. Ghez earned her PhD from Caltech in 1992, and went to UCLA for the opportunity to have access to the Keck I Telescope ¾, the world’s largest telescope. She used the Keck telescope to demonstrate the existence of a supermassive black hole at the center of our galaxy. Ghez shared one half of the 2020 Nobel Prize in Physics with Reinhard Genzel for this discovery.
