The formation is one of the most important discovered by astronomer Nicolas Louis de Lacaille, who saw it during his trips to South Africa, between 1751 and 1752. Now, with the help of three of the world's most renowned telescopes, the Jewel Box gets a new picture, one of the most detailed to date.

One reason for its name is the contrast that is visible between its pale blue and orange stars, as seen through astronomical telescopes. These colors reminded Herschel of some exotic jewelry that he had seen at some point. Structures such as !
this one are a gold mine for astronomers, as all stars were formed from the same gas-and-dust cloud and have, therefore, about the same age and brightness. Kappa Crucis is about 16 million years old. Usually, clusters are formed from anywhere between a few and several thousand stars, all of them bound together by a loose ...
