Milky Way loses its arms

After a bit of scientific amputation, astronomers have again reevaluated the shape of the Milky Way based on data from the Spitzer Space Telescope, and reduced the number of spiral arms from four to two. Back in 2005 Spitzer revealed that the Milky Way was in fact a barred spiral, as opposed to a “perfect” spiral as previously thought.
