Stars and Dust through Baade's Window
Explanation: Billions of stars light up the direction toward the
center of our Galaxy
. The vast majority of these stars are themselves billions of years old, rivaling their home
Milky Way Galaxy
in age. Together with interstellar dust,
these old stars
combine to create this
yellowish starscape
. Although the
opaque dust
obscures the true Galactic center in
visible light
, there is a low density hole in the
dust
on the right of the image. The region, named
Baade's Window
for the German
astronomer
who studied it, is
used
to inspect distant stars and to determine the
internal geometry
of the Milky Way.
Baade's Window
lies toward the
constellation
of the Archer (
Sagittarius
). APOD presents:
