Now, in the last few years, cosmic cartography has again redrawn modern science's picture of the galaxy, from the inside out.
Surprising new findings from this endeavor begin at the Milky Way's heart, where astronomers recently spotted a tendril of gas streaming toward the galaxy's central black hole. Next year, scientists will have a ringside seat for the first time as the matter swings perilously close to its doom.
