Hubble Spots Spiral Bridge of Young Stars Linking Two Ancient Galaxies

"NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light-years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen process."
