Bright speck­les of blue are a sure­fire way of telling that a galaxy is ac­tive and pro­duc­ing hot, young stars. NGC 4536 is cer­tainly ac­tive, and is an ex­am­ple of a star­burst galaxy. These ga­lac­tic spec­i­mens pro­duce stars at an ex­tremely rapid rate, to the ex­tent that they use up their cos­mic gas more quickly than it can be re­plen­ished. The fate is sim­i­lar for the stars within the galaxy, which burn in­tensely and ex­haust their gas sup­ply within a rel­a­tively short pe­riod of time.
