Diving for pearls with the Hubble Space Telescope
Rochester NY (SPX) Jul 16, 2014
Stars forming like a string of blue pearls along two elliptical galaxies could be the result of a galactic merger, according to an international team of astronomers. The structure could reveal rare insights about elliptical galaxies. Scientists from Rochester Institute of Technology helped analyze data from the Hubble Space Telescope showing elliptical galaxies coalescing at the core of a dense galaxy cluster. The study is part of a program sponsored by the Hubble Space Telescope-an internat ... read more
