Jeweler of Stars. Shows in the Universe

The great variety of colors of the stars in this open cluster is the basis of its name: The Jewelry Box. One of the bright central stars is a red supergiant, in contrast to the blue stars that surround it. The cluster, also known as Kappa Crucis contains over 100 stars.

Open clusters are younger, have fewer stars, and have a higher blue star ratio than globular clusters. The Jeweler is at a distance close to 7500 light years, so that the light we see today was emitted from the cluster even before the great pyramids in Egypt were built.

The Jeweler, photographed above, whose approximate size is 20 light years, can be seen with binoculars towards the constellation of the Southern Cross.
