Hace 5 días · The German astronomer Walter Baade (1893–1960) in 1943 associated a nebula at a distance of about 5 thousand parsecs, that is 16 thousand light years, to that astrophysical relict. With the progress of infrared astronomy and X-ray astronomy, occurred in the second half of the twentieth century, the nebula could be observed in detail and we can study its morphology.
Hace 1 día · The term supernova wasn’t used until the 1930s when Walter Baade and Fritz Zwicky began studying this new phenomenon. They postulated that the energy generated from a supernova was due to the gravitational collapse of ordinary stars into neutron stars.
Hace 2 días · In 1943, Walter Baade was the first person to resolve stars in the central region of the Andromeda Galaxy. Baade identified two distinct populations of stars based on their metallicity, naming the young, high-velocity stars in the disk Type I and the older, red stars in the bulge Type II.
Hace 1 día · Together with colleague Walter Baade, Zwicky pioneered and promoted the use of the first Schmidt telescopes used in a mountain-top observatory in 1935. In 1934 he and Baade coined the term " supernova " and hypothesized that supernovae were the transition of normal stars into neutron stars , [17] as well as the origin of cosmic rays .
Hace 5 días · In 1944 the German-born astronomer Walter Baade announced the successful resolution into stars of the centre of the Andromeda Galaxy, M31, and its two elliptical companions, M32 and NGC 205.

Hace 5 días · The idea of establishing a common large observatory that joined the European astronomers was born in the spring of 1953, in the mind of the renowned astronomer Walter Baade.
Hace 2 días · Walter Baade entdeckte in der Folgezeit rund 100 weitere Kugelsternhaufen, die im Jahr 1945 publiziert wurden. Dabei wurde wiederum eine verminderte Helligkeit mit diesmal 2,5 mag festgestellt, [162] die Baade dann rund 10 Jahre später durch eine berichtigte Entfernung auflösen konnte. [56]
