For the first time astronomers have measured how a galaxy's spin affects its shape -- something scientists have tried to do for 90 years -- using a sample of 845 galaxies. Because a galaxy's shape is the result of past events such as merging with other galaxies, knowing its shape also tells us about the galaxy's history. The team made its findings with SAMI (the Sydney-AAO Multi-object Integral field unit), a game-changing instrument.
