    Star clusters are aggregates of stars that formed together. They range dramatically in size, forming out of anywhere from a few hundred stars to many thousands. A young but fairly massive star cluster is known to exist in the Large Magellanic Cloud, a companion galaxy to our own Milky Way. This giant star cluster may not be just one cluster, but actually a merger of at least two clusters. Observations with the Hubble Space Telescope have illuminated the circumstances of this interesting region.
