Erik Rosolowsky
Stellar Clusters: The Benchmarks of Galaxies

Star cluster  Westerlund 2 (Hubble)

Star clusters are a favourite deep sky object for observers, but clusters also play a vital role in astrophysics.  Because all the stars in clusters are formed at the same time, they serve as essential tools for galactic archaeology and surveying.  In this talk, I will describe the cosmic life and times of clusters and present some of the ways that astrophysicists use clusters.  Finally, I will describe why we think that our Sun formed in a cluster and the search for stars from our old neighbourhood.
