Hubble Images Four Merging Dwarf Galaxies

This Hubble image shows Hickson Compact Group 31, a group of four galaxies located some 166 million light-years away in the constellation of Eridanus. The bright, distorted object is actually two colliding dwarf galaxies. The bluish star clusters have formed in the streamers of debris pulled from the galaxies and at the site of their head-on collision. The cigar-shaped object to the right is another member of the group. A bridge of star clusters connects the trio. A longer rope of bright star clusters points to the fourth member of the group. The bright object in the center is a foreground star. Image credit: NASA / ESA / J. Charlton, Pennsylvania State University / G.

This Hubble image shows NGC 6558, a globular cluster located 23,000 light-years away in the constellation of Sagittarius. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) instrument. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
