Journey to NGC 4755: The 'Jewel Box' Star Cluster | Hubble
The initial view in this zoom shows the rich star field where NGC 4755 nestles and then moves in to the detailed Hubble image of the Kappa Crucis Cluster, or Jewel Box, itself. The final image is a "close-up' view from the NASA/European Space Agency Hubble Space Telescope of NGC 4755, or the Jewel Box cluster.
Several very bright, pale blue supergiant stars, a solitary ruby-red supergiant and a variety of other brilliantly colored stars are visible in the image, as well as many much fainter ones, often with intriguing colors. The huge variety in brightness exists because the brighter stars are 15 to 20 times the mass of the Sun, while the dimmest stars are less than half the mass of the Sun. This is the first image of an open galactic cluster with imaging extending from the far ultraviolet to the near-infrared.
