Biography

Reinhard Genzel led one of two teams that, over decades, tracked the orbits of stars whipping around the centre of the Milky Way. Their motions revealed an invisible object of four million solar masses packed into a tiny region — a supermassive black hole, Sagittarius A*. Genzel shared the 2020 Nobel Prize in Physics with Andrea Ghez and Roger Penrose.
