Messier 3 (also known as M3 or NGC 5272) is a globular cluster of stars in the
northern constellation of Canes Venatici. It was discovered by Charles Messier
on May 3, 1764, and resolved into stars by William Herschel around 1784. Since
then, it has become one of the best-studied globular clusters.
