M15 is easily accessible during the summer months. Its core is not quite as bright as in other globulars and the overall stellar distribution is fairly uniform across its 12 arcminute extent.

Despite many decades of progress in understanding the evolution of star formation and stellar populations in galaxies, we have still fundamental questions that have remained unanswered. These include: how do stars cluster in galaxies, and how do these structures evolve in time? ... How are popular star formation rate indicators affected by the recent star formation history of a galaxy? ... The answers to these questions inform our theories for the evolution of galaxies through cosmic times. ...
