DWARF GALAXY SPOTTED BEHIND GLOBULAR STAR CLUSTER
This is a Hubble Space Telescope image of a concentration of stars within the globular cluster NGC 6752. Hidden among the stars is an image of a background galaxy that is much farther away. The diminutive galaxy, named by its discoverers as Bedin 1, measures only around 3,000 light-years at its greatest extent — a fraction of the size of the Milky Way. Not only is it tiny, but it is also incredibly faint. These properties led astronomers to classify it as a dwarf spheroidal galaxy that is as old as the universe.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: F606W Orange: F814W |
