Open star cluster, located 6,445 light-years from Earth, in the constellation of the Southern Cross (Crux).
It was called the Jewel Box by the English astronomer John Herschel, who described it as a “coffin of gemstones of various colours”, noting that “this cluster, while neither large nor rich, is an exceptionally bright and beautiful object when viewed through an instrument of aperture sufficient to show distinctly the very different color of its constituent stars, which give it the effect of a superb piece of fancy jewelry.”
