Astronomers have divided imagery of the Andromeda galaxy taken by NASA’s Hubble Space Telescope into thousands of squares 300 light-years on a side and determined the history of star formation within each parcel to gain a comprehensive view of the galaxy’s past. This image highlights two such regions.
Massive stars are bluer and short-lived, while less massive stars are redder and longer-lived. As a result, areas that have experienced recent star formation (1) tend to have a larger fraction of blue stars, while areas with less recent star formation (2) typically have a redder population.
