By situating stars in time and place, astronomers can retrace history and infer how the Milky Way was built, piece by piece, over billions of years. The first major effort to study the primordial ...

On top of this, some spirals have a central bulge or bar from which the spiral arms extend. That makes astronomers’ conclusion that the Milky Way has four arms, something of a surprise. If it turns ...
