Omega Centauri is a globular cluster located in the constellation Centaurus. It is one of the largest and brightest globular clusters in our Milky Way galaxy, containing millions of stars. Omega Centauri is approximately 15,800 light-years away from Earth and has a diameter of about 150 light-years. This cluster is unique because it shows signs of having multiple populations of stars with different ages and compositions. Unlike most globular clusters, which typically contain stars of similar age, Omega Centauri's diverse stellar population suggests a complex formation history, making it a subject of interest for astronomers studying the evolution of star clusters.
