COSMIC MESSAGE

Star clusters appear static in photos, but their stars are constantly moving and changing brightness. Globular cluster M3, shown here in a time-lapse, reveals these changes over a single night. Most of the variable stars visible are RR Lyrae stars, which pulsate predictably. While a star takes about 100,000 years to cross the cluster, its brightness can fluctuate noticeably in less than a night.
