Coating the night sky like sprinkles on an ice cream scoop, this globular cluster contains an incredible half-million stars! This 8-billion-year-old cosmic bauble called Messier 3 is one of the largest and brightest globular clusters ever discovered, seen here in a @NASAHubble image. What makes Messier 3 extra special is its unusually large population of variable stars — stars that fluctuate in brightness over time. New variable stars continue to be discovered in this sparkling stellar nest to this day, but so far, we know of 274, the highest number found in any globular cluster by far.
