But a group of astronomy detectives has now reconstructed part of the cluster\u2019s history and identified a five-star smashup as the most likely cause for Mel 34\u2019s high-speed departure [<a href=\"https:\/\/physics.aps.org\/articles\/v18\/134#c1\">1<\/a>]. This unlikely collision offers important information about the fate of young, massive stars.<\/p>\n<p>The star cluster R136 is a grouping of around 60,000 stars in the Large Magellanic Cloud, a small galaxy 160,000 light-years from Earth. The cluster is about 2 million years old, which is fairly young as clusters go. \u201cR136 is very special because it\u2019s the youngest and the most massive star cluster in the local group of galaxies,\u201d says Simon Portegies Zwart from Leiden University in the Netherlands. Previous studies of R136 have identified several dozen \u201crunaway\u201d stars that have been kicked out of the cluster. Runaways are common around clusters, but their origins are not always clear. R136 is young, so it\u2019s a good place to study the process that produces runaways, Portegies Zwart says.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A detailed analysis of a stellar cluster has led to a possible explanation for several fast-moving runaway stars around the cluster.
