Summary[edit]

Description
English: This image is a “close-up” view from the NASA/ESA Hubble Space Telescope of NGC 4755, or the Jewel Box cluster. Several very bright, pale blue super-giant stars (eg. κ Crucis on the left, HD 111934 on the lower right and HIP 62913 in the middle right), a solitary ruby-red super-giant (HIP 62918 - upper right) and a variety of other brilliantly coloured stars are visible in the image, as well as many much fainter ones, often with intriguing colours. The huge variety in brightness exists because the brighter stars are 15 to 20 times the mass of the Sun, while the dim points 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-infra-red.
