In an intensive citizen-science-aided survey of Hubble telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. By nailing down what percentage of stars have a particular mass within a cluster (the Initial Mass Function), scientists can better interpret the light from distant galaxies and understand the formation history of stars in our universe.
