Baade's Window
Baade's Window is an area of the sky with relatively low amounts of interstellar dust along the line of sight from Earth. This area is considered an observational "window" as the normally obscured Galactic Center of the Milky Way is visible in this direction. This makes the apparent Large Sagittarius Star Cloud visible. It is named for astronomer Walter Baade, who first recognized its significance. This area corresponds to one of the brightest visible patches of the Milky Way.
