Back in the mid-1940s, Walter Baade discovered this patch in the sky while looking for the Milky Way’s center. Until this discovery, we knew very little about the structure of the Milky Way, and didn’t have a clue where its center was. Fortunately, Baade recognized the importance of this discovery.
Because of the clarity of our sight-line to Baade’s Window, scientists use it to study and measure the stars in the central bulge. Overall, there are six ‘windows’ where people from Earth can see the central bulge. Baade’s window is the clearest of the six. As an added bonus, scientists have also discovered planets orbiting around stars in the central bulge by using a process known as microlensing. However, due to radiation from the galactic center, these planets would not be habitable for our type of life.
