This Hubble Space Telescope image shows a young, open star cluster known as NGC 4755 or the Jewel Box. Just like old school friends that drift apart after graduation, the stars in open clusters only remain together for a limited time. They disperse into space over the course of a few hundred million years, pulled away by the gravitational tugs of other passing clusters and clouds of gas.
The Jewel Box is a spartan collection of just over 100 stars. The cluster is about 6,500 light-years away from Earth, which means that the light we see from it today was emitted before the Great Pyramids in Egypt were built.
Head outside and you can see it for yourself! The Jewel Box is visible to the naked eye, but will masquerade as a single star. Grab a pair of binoculars if you want to see more of the cluster’s sparkling stellar population. It is located in the southern constellation of the cross (Crux).
