A photo of Walter Baade, seated at his desk. He is wearing a light colored jacket and tie with a white shirt. Baade is looking directly at the camera, and he is holding a cigarette in his left hand. He has a sort of detached, careless look. Definitely an MI6 spymaster.

   Astronomer who hypothesized the existence of neutron stars, or insouciant MI6 spymaster from a Graham Greene novel? Maybe he's about to coin the term supernova, or maybe his contacts in Marrakesh are about to smuggle you to safety. Hard to say.

   Astronomer Walter Baade was born #OTD in 1893. With Fritz Zwicky he introduced the term "supernova" and hypothesized the existence of neutron stars.
