Wilhelm Heinrich Walter Baade (March 24, 1893 – June 25, 1960) was a German astronomer who worked in the United States from 1931 to 1959.
Wilhelm Heinrich Walter Baade (Preußisch Oldendorf, 24 de março de 1893 — Göttingen, 25 de junho de 1960) foi um astrônomo e astrofísico alemão. Participou da 11ª Conferência de Solvay, em 1958.
Born in Germany and educated at Göttingen, Walter Baade worked at the Hamburg Observatory from 1919 to 1931 and at Mt. Wilson from 1931 to 1958. He and Fritz Zwicky proposed in 1934 that supernovae could produce cosmic rays and neutron stars, and Baade made extensive studies of the Crab Nebula and its central star.
1 de nov. de 2002 · In the autumn of 1943, Walter Baade, at the Mount Wilson Observatory, managed to resolve into individual stars the inner amorphous region of the Andromeda galaxy and two of its companion galaxies. The brightest stars were yellow giants; he found no highly luminous blue or red stars.

Although less well known outside the field than Edwin Hubble, Walter Baade was arguably the most influential observational astronomer of the twentieth century. Written by a fellow astronomer deeply familiar with Baade and his work, this is the first biography of this major figure in American ...
German–American astronomer Walter Baade is remembered for three major contributions to observational, extragalactic astronomy: the recognition of two basic population types of stars, the characterization (with Fritz Zwicky ) of supernovae as a distinct class of event with energy derived from the collapse of a normal star to a neutron star, and t...
Walter Baade was one of the great astronomers of the twentieth century. He opened up the fields of study of stellar and galactic evolution that have made up so much of astronomy in our time, but which were sterile and unproductive before his discovery of the two stellar populations, young stars and old.
