Description:

The Jewel Box (NGC 4755) is an open cluster in the constellation Crux, which includes the Southern Cross, and originally discovered by Nicolas Louis de Lacaille in 1751–1752. This cluster was later named the Jewel Box by John Herschel when he described its telescopic appearance as "...a superb piece of fancy jewelry". It is easily visible to the naked eye from the Southern Hemisphere, as a hazy star some 1.0° southeast of the first-magnitude star Beta Crucis, which is visible to the right in this image. We first saw the Jewel Box Cluster two years ago, on an Indonesian Eclipse trip, and revisited it last month, in Cusco, Peru. This cluster is one of the youngest known, with an estimated age of 14 million years. It has a magnitude of 4.2, is 6,440 light years from Earth, and contains just over 100 stars.
