#Baades window

• Baade — A proper surname of German origin, predominantly associated in scientific contexts with the astronomer Wilhelm Heinrich Walter Baade (1893–1960). His foundational contributions include defining the two distinct stellar populations (Population I and Population II), recalibrating cosmic distances by revising the Cepheid period-luminosity relation, and discovering major asteroids, with his name being given to the lunar crater Baade, asteroid 1501 Baade, and an observational window toward the galactic center.
