The Milky Way is a spiral galaxy with curved arms stretching out into space. Most depictions of our galaxy show it as being rather flat, but data from the Optical Gravitational Lensing Experiment at the university suggests the opposite. The team, who describe our galaxy as being less a flat disc and more a “wobbly, uncooked pizza crust,” mapped the position of a specific type of star called Cepheids. Cepheids are pulsating stars and it’s easy for researchers to measure the distance between them and Earth. Using data from 2,431 Cepheids, the team was able to create its incredibly detailed...
