Clues to Star Birth in Neighbouring Galaxy

Astronomers with the help from citizen scientists, have analysed images of 2,753 young, blue star clusters in the neighbouring Andromeda galaxy (M31), and have found that M31 and our own Milky Way have a similar percentage of new-born stars based on mass.
By nailing down what percentage of stars have a particular mass within a cluster called Initial Mass Function (IMF), scientists can better interpret the light from distant galaxies and understand the formation history of stars in our universe.
Stars are born when a giant cloud of molecular hydrogen, dust and trace elements collapses.
