Andrea Ghez

Andrea Ghez is a renowned American astrophysicist, best known for her groundbreaking work in studying the center of our galaxy, the Milky Way. She played a key role in providing evidence for the existence of a supermassive black hole called Sagittarius A*, which is located at the galaxy's core. In 2020, Ghez was awarded the Nobel Prize in Physics for her contributions to our understanding of black holes and galactic dynamics. Her research uses advanced imaging techniques to observe stars near the galactic center, revealing insights into gravity's effect on these stars and the nature of black holes.
