This image from NASAтАЩs┬аHubble Space Telescope showcases┬аMessier 3┬а(M3), one of the Milky Way galaxyтАЩs most massive globular clusters, or spherical collections of gravitationally bound stars.┬аGlobular clusters┬аare made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are sprinkled around the outer regions of the Milky Way.
