A team of researchers at the University of Warsaw has created the most accurate 3-D model of the Milky Way Galaxy to date. In their paper published in the journal Science, the group explains how they used measurements from a special group of pulsating stars to create the map.
Using Cepheid variable stars, this team has taken a look at the proper motion of the galaxy to take a snap shot of what it really looks like. Unlike the traditional notion of a flat whirlpool spiral, it’s actually more like a pizza tossed into the sky, spinning quite unevenly.
