Hubble Telescope Captures Stunning Images of Ancient Star Clusters

NASA's Hubble telescope captured a stunning image of the M55 star cluster, located 17,000 light-years away in the Sagittarius constellation. The cluster is made up of around 100,000 stars, with 55 of them being variable stars. Despite its relative brightness, it is difficult to observe from Earth due to its lack of a dense core and faint stars.
